    Formula C1 Brake issues on 2014 Stumpjumper FSR Comp 29er

    I recently got a 2014 Stumpjumper FSR 29er Comp that came standard with Formula C1 brakes. After two rides they were real spongy with hardly any stopping power and the levers were pulling all the way to the bars. I took the bike back to my LBS and they bled them and supposedly sorted them out. But today when I went to pick the bike up and tested the brakes both leaked from where the reservoir connects the hose. So much so that a squirt of fluid got in the LBS guys eye when I squeezed the lever and he went of to the hospital to have it checked out. This is the second bike that this LBS has had to remove the Formula C1 brakes from and send back to the Specialized dealer here in Cape Town for them to asses and work out if covered by the warranty. Does anyone know if this is a known issue? I must say I'm totally disillusioned wit the C1's. They were not very impressive at all and I they felt detracted from the otherwise super cool ride of the stumpy. Regardless of the warranty claim I think I will put SLX's on the bike. I believe that they are really good brakes for the money and should give much less trouble.

    My C1 brakes is working flawless. On the other side I really liked the 2011 XX brakes and hated the 2013 XTR brakes.

    I have the C1s on my 2014 sj comp evo and they are terrible, the front brakes make a lot of noise ...loudest I have ever heard. The rear brakes make the entire frame vibrate all the way through the handle bars. its so bad you don't even want to ride it. I have seen a few more stories on the web like this and to be honest cant believe they sell bikes for this much money that have so many issues.

    If I was in that position, I would be asking to have them switched out to SLX brakes. They have been flawless on my SJ Elite. I did demo an SJ with the C1s, and although they functioned fine during my ride, the rear did squeal quite a bit.

    I too am having a lukewarm experience with the C1s on my Enduro 29. They just feel a bit vague and spongy. It's hard to tell when the pads are making initial contact with the rotor and hard to judge how much lever "squish" is needed for a given scenario. I definantly prefer a more direct feel. I had to dial the levers out from the bar a bit farther than I would like to find the sweet spot for lever throw. Additionally the rear brake pumps up with repeated squeezes but reverts to normal if you leave it alone for a couple seconds. Has anyone tried bleeding with any success?

    I'm about to pull the trigger on some SLX or XT brakes but I suppose I should give these a few more rides to make a final decision.

    Why Because Sram brakes Suck!

    Formula brake are great and it's down to bad cycle Mechanic's that do not know how to work on them!

    I've had the exact same experience with my Stumpy. And they are not even behaving the same. Front brake is super sensitive, almost digital and just wants to lock out. Rear brake works fine one minute and then on the next downhill there’s nothing when I pull it. It comes back when i pump the brake a bit.

    Just dropped it off at my LBS and they said they’ll try to send it back. The mechanic told me I’m not the only one complaining. Time for a recall Specialised?

    Have you tried to bleed the brakes? If not, do it yourself or let your lbs to do it for you.

    Ditto. The shop mechanic should bleed the brake for you before sending it back. If the same issue happens after a proper bleed, then it would probably be a warranty issue.

    Reminds me of the South Park episode in which they resorted to cannibalism after being snowed in for a few hours.

    My Enduro came with the C1 brakes which failed on my first ride. Turns out the rear brake was leaking fluid,

    LBS did send in for warranty replacement; while that was happening I ordered XT brakes front and rear and couldn't be happier.

    I didn;t use my C1's past the first ride so I couldn't say good or bad but I do want confidence in my brakes and I have that 100% in my XT's ; this was not how I felt with the C1's.

    Re: Formula C1 Brake issues on 2014 Stumpjumper FSR Comp 29er

    To those having squishiness problem with this brake... Have you tried the setup described here?
    http://youtu.be/Z-Sm2gXIjNE
    The Stumpjumper Comp and Evo are two of the possible upgrades I'm considering for this summer. But if it turns out the Formula brake is really bad, I will just get the Crave.
    What works for me may not work for you. What's best for you depends on many factors. We are different from each other.

    Just had the same experience with my new stumpy evo. Rear c1 failed after 3 weeks riding. Found out that there is a bad batch of master cylinders. Waited 3 weeks for silverfish to repair and they came back in a worse state than previous. Specialized sent up a brand new set of levers and caliper that lasted 5 miles!!!!! I disagree with other members on this thread regarding mechanics not knowing how to bleed properly. Basically the product is crap, the backup is crap and specialized are the worst offender for speccing inferior product on an otherwise good product. They are solely responsible for this and should be accountable. They were five minutes away from having a bike handed back to them that was "unfit for purpose" and have only redeemed themselves by arranging to swap for Slx brakes

    Sorry to hear about your guys continued problems.
    My brakes feel just slightly squishy so the levers come back further then I would like. I have been told by the bike shop they are difficult to bleed. However outside of that they have been good. They are very quite almost never make noise. Hopefully you are all able to get them sorted soon. I know bad brakes can really ruin the riding experiance

    I've had no problems, they work flawlessly. Based on some of the reports here though, I'd replace the lines and all associated hardware and then do a bleed. Calipers and levers are pretty simple and "spongy" levers and levers that pull to the bar is indicative of one thing, air in the lines. Air gets in the lines because fluid gets out. As a shop mechanic, disc brakes are rather simple contraptions. They all work the same and while there are some small differences as to how they are bled, the concept is generally the same. Where you likely get the biggest issues are shops/mechs that do not use the proper bleed valves/adaptors, don't have a power-bleed set or a proper (big enough) bleed needle, basically short cuts. Although the concept is simple, it's probably one of the biggest dividing lines between "shops that know what they are doing" and ones that "like bicycles and selling stuff". That and fork rebuilds.

    Just got my 2014 SJ HT Evo... stoked on the bike for the price, but....
    Front brake was wet around fitting for hose to lever body connection. Brake was crap and would go to grip.
    Will try bleeding tomorrow.
    This is not a "mechanic" issue.
    It is a QC issue.
    The more time your LBS mechanic has to spend trying to sort and solve the issue the more SBC has to credit the shop for time that shouldn't be needed to repair a new bike.
    Like mentioned above; this seems to be deja vu of the horrible Avid brakes.

    I'll report back after I attempt to bleed and assess why the fitting is leaking.

    You're better off saving your time and frustration and putting on a set of reliable XT brakes

    Eh, I gotta at least try, if not so much for the hope of them actually working as much as my own satisfaction and knowledge to try and figure out what is going on. If they don't work then they don't work, and at least that way I'll know from firsthand attempt.
    But that said, this is why I came on here before tearing into them tomorrow; just to see if anyone posting here has a solution or experience on exactly what SBC may do in the case that these are just lemons!

    Had a Trek Rumblefish that came with stock Elixir 3 brakes, which I didn't like at all So I decided that my next bike won't have any Avid brakes!

    Before ordering my Enduro 29 I read a that the Formula C1 brakes are not powerful enough, especially not for a bike like the E29.

    So, the first thing I told my LBS as I ordered my E29 was: Shimano SLX (scond thing was X9 shifters...), and a few days later I stepped out of LBS door with E29 comp and SLX brakes on.

    Couldn't be happier with the SLX. Very very powerful brakes ( I only use one finger on the brake lever), very quiet, excellent modulation and easy set up.

    If you look at the new SJ 650b specs, you can see that the comp model has Shimano Deore M-615, while the expert model has Shimano XT's!

    I'm glad that Specialized finally did her homework, and maybe the 2015 Specialized line up (at least the FS bikes) would have only Shimano stock brakes...

    P.S.
    Regarding those of you that have issues with Avid or Formula brakes - I highly recommend you to throw them away and get yourself some new SLX or XT's instead
    I'm sure you can feel the difference right from your first ride, just like I did.

    Bled my Formula C1 brakes using a recent Avid bleed kit.
    Went through them both twice.
    So far so good. Lever feel is positive and even between sides.
    HUGE improvement instantly over what they were brand new!!!

    Now just to see how long they will hold a bleed after I get some heat in them on some rides!
    I'll try to remember to post up an update.

    The C1's on my Enduro have been the most inconsistent brakes I have ever ridden with. The front is super spongy and there is not much between fully open and locked up, and the back it depends on whether I have been using the brakes or not. On an extended technical downhill, the brakes build up pressure to the point of just touching them locks up the back, but when you let it go for a while, it loses all pressure and you have to really hammer on the lever to get some traction. have definitely been over the bars a couple times now purely because of the inconsistency on the pressure required to actually break. Hoping my LBS can sort this out today... (I know, get the breaks bled and see how they perform afterwards, but they were bled when I got the bike two months ago and this shouldn't be how they perform straight up - I didn't have a problem with my Avid Elixer RSL's in two years... now straight out of the box!)

    Brakes are not in my opinion a "Like to have" product. I had problems on my first ride and them immediately ordered XT brakes front and rear.

    Going down hill with my 200lb butt and the 30lb bike at 25 MPH on dirt is no time to say "I hope my brakes work"

    I'm surprised how many people are going for new brakes so soon straight out of pocket and not pushing Specialized/LBS for a credit!!??

    That is what I'm wondering about. If mine fail again I am seeking that route.
    I already have XT's/SLX's/Hopes/avids all that I can put on this bike, but why should I have to at this level of a bike and already spending money? I went this box bike route (which I typically avoid in favor of custom) seeking support, consistency, and reliabilty for a workhorse bike!

    I agree; but I don't think you will receive a credit but will get a replacement like I did. They sent mine in for warranty replacement and yes Specialized did send me new ones but that took 2 weeks.

    I am impatient and do not want to hang up the bike for 2 weeks while I wait.

    called my lbs and they didn't want to credit me or want to give me a price discount and actually i found that they wanted to overcharge me for a set of slx brakes front and back. Was very disappointed as i would have spent money if they worked with me a little. Found a bike shop close to me that doesn't deal with specialized but gave me a great deal on shimano slx brakes and i just ordered them. will be here friday or monday. Very sad that the shop i got my bike from didn't want to throw me any bit of a deal

    I have 45 miles and i've had them bleed twice and i have bleed them and the lever feel just isnt there. my avid elixir 5's i bleed every year and they feel awesome. these formulas i have been having problems since day one. I won't want them to be replaced with the same formulas. I was gonna swap the brakes off my santa cruz but my fiance rides that and i have the brakes dialed in perfectly on it. I know ill be much happier with the shimano slx brakes. and ill sell the formulas for whatever i can get for them. I love my stumpjumper. After i got the new rear wheel the brakes are the only thing that i am unhappy with.

    agree 100% but unfortunately in my experience my LBS's seem to be about double the price on parts. I want to support my locals shops but not at such a premium.

    Brick and mortars get beat up everyday with the internet; if they were just more in line I would be more than happy to do everything through my LBS.

    yeah i called all the local bike shops for pricing and the lbs i bought my brakes from i have never been to even though its 10 minutes from my work. A few shops i called wanted alot of money for the shimanos. some even were trying to charge me more than msrp. I called one shop and they said they needed to see the bike. before pricing me on it. Even though they are a specialized dealer and i have a brand new 2014 stumpjumper comp.. They didn't even want to go look at there model on the floor to price me up.. It's hard to find a reputable lbs.

    I have a 2014 Camber Evo and am having same issues with Formula c1 brakes. Horrible fog horn noise on back brake with a ton of vibration. I had LBS bleed front brake before first ride and it seems fine. But back is unusable.

    I had the same issue on my stumpy evo with the formula brakes. The fix was removing the screw that held the rear brake cable to the inside of the rear triangle. Not sure if the camber has the same design but it sounds like the same problem

    Thanks for the info. I will check that. My LBS put some brake quite stuff on it and the noise is gone but the brakes don't stop worth a crap with that stuff on them.

    I posted this in the 29er forum but someone replied with a link to this thread which is exactly where it belongs. Any help is appreciated! Thanks!

    2014 Stumpjumper Comp HT

    So I've been having issues with my front brake since I purchased the bike on 3/17. I took it in the first time and they said they fixed it. Happened again right away and took it in the second time and they told me they would need to have Formula authorize front brake pad warranty replacement which they did. It still makes a very annoying noise and now the front end shakes and vibrates when actuating the front brake. I went in again, third time and explained the issue. They checked the bike in and said they would need to contact specialized. Now they are telling me that specialized is going to send shimano deore brakes to replace the formula c1 brakes at no charge. Is that a downgrade? When they say they will replace the brakes do they mean only the front since that is the issue or both front and rear? I don't wanna have 2 different sets of brakes. What brakes are comparable in price/quality with the formula c1 that are on the bike now? Thanks in advance for your help! I really appreciate it!


    Thanks
    Isaac

    Formula C1 Brake issues on 2014 Stumpjumper FSR Comp 29er

    They will most likely give you a full set front and back. No the shimano deore brakes are good. Still use the servo system as the slx and up brakes. Only difference is they don't have ice tech pads and it doesn't have reach adjustment like the slx system.

    Formula C1 Brake issues on 2014 Stumpjumper FSR Comp 29er

    Problem was never the pads Idk why they replaced them. But good that they are stepping up to the plate. I threw my formulas in the dumpster after bringing them back to my lbs and complaining 2 times and them not discounting me a set of slx brakes and I ended up buying them from another lbs

    Just a quick update on my C1's; now have a lot more ride time and over 200 singletrack miles on them and they are both inconsistently giving off the odd resonance and vibrating with "fog horn noise". This is in dry conditions.
    Front is also on bleed #2.

    Have C1's on my 2014 SJ HT carbon comp. So far no problems. They are sometimes loud, but I just live with it.

    Probably will go with Xt's down the road.

    I have had my 2014 FSR Comp Evo 29 for several months... the back brake has had noise and severe vibration issues on and off since day one (it brays like a donkey on heat). The only good thing is that it is so bad that I am far more conscious of staying off the brakes!....
    SOLUTION: My local Specialized concept store has now confirmed to me that the issue is related to pad movement within the caliper ... solution ... replace with Shimanos (or Avids if you prefer) ... nice one Specialized - that's good customer service (although puzzled why it has taken them so long to admit the issue).

    @rularn..... No apparently not... Issue is with the calliper ...which is why the 2015 model switches to shimano. Suggest going to lbs or concept store and politely ask them to request a brake swap with specialized customer service.

    I've had my SJ EVO for less than a week and ditched the Formula brakes already. With everything I read on them on this forum, I ordered XT brakes at the same time I bought the bike. Had a good deal at JensonUSA - $97 each, LBS cost was $125 each so he told me to get them online (and he'd order some as well!). Keep in mind that you will need a new pair of sram shifter rings to hold your shifters as they can't be bolted on the shimano brakes as they did on the Formula.

    Unhooking the hose from the plastic piece that secures it to the seatstay worked for me (Camber EVO).
    Rear brake feels a little inconsistent but vibration and noise are gone.

    I had the same problem and my fix was to tighten the rear axle, the sound and vibration disappeared!

    Had exactly the same experience on my new Camber Evo. Horrendous vibration from rear brake, making it almost unusable. Disconnected seatstay clip and problem solved. Is a pleasure to finally use the bike as intended. Practiced some rear-wheel steering today. Still a hint of vibration persists, but doesnt affect performance.

    Thanks for the forum suggestion. But I must say, this is my first proper expensive full suss bike, and am slightly shocked that specialized can release a bike with such a serious problem, leaving me to arse around on the internet for the solution. Clearly they are aware of it.

    After my LBS installed the S-Works carbon seat stay all my problems have went away. Brakes have been working great on my Camber Evo.

    I want to buy a Specialized carbon 29 fsr that has formula c1 brakes but has anyone here called Formula to ask them about it? It seems like if it was the brake caliper like someone here suggested, then formula would replace parts not specialized replacing the seat stay. Sounds like it's a frame issue, not a brake issue.

    I gave up and put XT's on my bike and threw the C1 junk in the trash. The bike is now 100% more enjoyable to ride with solid braking feel and no brake vibration.

    Sorry if this has already been stated but the fluid you saw was most likely assembly fluid from the factory. It looks identical to dot fluid but it isn't. It's very common to see new formulas seep a little fluid from the compression nut on the lever. There is a very simple procedure to purge the excess assembly fluid from the master cylinders that your lbs didn't do.

    I purchased my 14 Stumpjumper evo ht a couple months ago and put 25 miles on it before the C1s started having problems. Brake levers could be pulled back to bars and lost some power, as well as noisy and had some vibrations. Took it back to my LBS where I bought it and they bled the brakes and made some adjustments. Rode it around the parking lot and all was well. Next ride problems started coming back. Back to the LBS and was told they were done with the c1s. Had a bunch of problems and said specialized was offering a free swap to shimano Deores. Asked if I could upgrade to XTs and they said if I paid the difference. Awesome service for sure....one of the reasons I bought a specialized was because of how easy there warranty was. No sending off requests. LBS said that they take care of it and specializes pays them for it. Makes sense that a manufacturer would trust their dealers as professionals. Just thought I would share my experience...don't give up on your lbs yet and order online. See if they will work with you on a shimano upgrade

    Glad to hear your lbs took care of you. I am surprised they didn't get you on xts but whatever. We have had several issues with formulas on new bikes and always work with our customers to get them on good brakes or carbon stays if it's a frame issue.

    Formula C1 Brake issues on 2014 Stumpjumper FSR Comp 29er

    My lbs wouldn't even give me 10% off my brakes and they wanted to overcharge me for the brakes. I don't expect them to compete with online prices but asking over retail for brakes after I've had the bike for 2 weeks. And brought it back twice for brake problems.

    So the OFFICIAL SOLUTION (as per Concept Store and Specialized UK customer care team) is that they will swap out the Formula brakes for Shimano's free of charge. I then paid the difference to upgrade to XT's. Since I have been running on the XT's the bike has been perfect (XT's are Sooo much better!). The basic problem was a fault with the calipers on the C1's that meant the pads were moving inside them. So if you have this issue with the C1's ... get your LBS to contact Specialized and they should agree a swap.

    Yep i was the same on my sj, before i sold it.

    Formula C1 = crap. Spongy levers and terrible rotor noise.

    Next bike on my enduro i went straight for XT's and never looked back.

    Might try something else on next bike.

    Maybe a 4pot.

    Im pretty heavy and whist a 4pot might be over kill for some i need all the help i can get.

    That is what I'm wondering about. If mine fail again I am seeking that route.
    I already have XT's/SLX's/Hopes/avids all that I can put on this bike, but why should I have to at this level of a bike and already spending money? I went this box bike route (which I typically avoid in favor of custom) seeking support, consistency, and reliabilty for a workhorse bike!
    Hi all,

    just a comment from a biker in Germany: same bike (stumpy evo 2014 with c1) and same problem. My LBS has already changed the brakes (unfortunately) to a new pair of c1. The vibration problem of the rear brake should have been resolved by mounting a carbon seat stay. This came carbon matte and my SJ is glossy black and white. So the stay will be varnished now.

    What I found interesting is the warranty issue. Why do some guys here buy Shiomano breaks without asking for rectification (is this the right word?) - is it due to US laws?

    After a certain point (tried with organic brake pads, tried to remove brake tubes from the frame - all this without a result) I think its up to the LBS and Specialized ...

    Anyone happy with his 2014 Stumpjumper Evo?

    Cheers from Karlsruhe/Germany
    Wolfgang

    I haven't had any problems with noise or vibration with my C1s, but my rear brake performance has gone from mediocre to bad. Piston in the lever goes all the way to the hard stop. I can barely lock up the rear wheel and have hardly any stopping power. Asked my LBS today about the Deore replacement that Specialized is offering. I'll find out Monday what they say. Might pay the difference and go XT if they say yes.

    I never heard about a replacement here in Germany - but I heard of an Italian Specialized Dealer who changed all C1 to XT. Maybe my LBS is in a weak position while not selling so many Specialized bikes ...

    Forgot to mention that now the rear shock will be changed and the command post needed the first complete service after a few weeks.

    Had same brakes on my Stumpjumper Comp Evo 29, after one ride i replaced them with Shimano Zee with cool tech rotors.

    With Formula there was almost no stoping power, loud noise, whole bike was shaking...

    Update:

    Specialized was very familiar with the problem of poor brake performance where the lever goes to the bar or hard stop depending on reach adjustment. They used to just replace the C1s with Deore brakes. Recently they worked with Formula on developing a new bleed procedure so now they try bleeding the brakes with this new procedure.

    Hopefully this takes care of my brakes until I can pick up a set of Sram Guide RSCs.

    Update #2:

    My LBS said they had been struggling to get a good bleed on my C1s all day even with the new bleed procedure. They were going to keep trying and told me to call in the morning for an update. If they can't get them bled to a satisfactory level, I'll try to have them push Specialized for a set of Shimanos or Guides.

    Update #3:

    My LBS couldn't get a good bleed on the C1s even after multiple attempts. They're going to have Specialized send out a new set of brakes (not sure if they'll be Formulas or something else). In the mean time the owner took off his SLX brakes from one of his bikes and installed them on my bike so that I can keep riding. Now that's customer service!

    Update #4:

    Specialized offered to either replace the C1s with Shimano SLXs or I can choose any brake of my choice and pay the difference in cost. I chose to upgrade to SRAM Guide RSCs.

    I had same issues of the brakes. My LBS tried to bleed brakes and contacted specialized. They are replacing both front and rear brake setups. I don't remember which ones they said they are replacing them.

    I have 2014 Stumpy FSR 29 with Formula C1 also and I'm not very happy with it, it's been over a year. I'd like to upgrade the brake so please report back, did you have to replace the rotor also ? Enjoy your new brake
    Thanks,

    Before riding, Formula suggests as part of the start-up procedure is to remove the wheel(s) and compress the brake lever until the pads touch. You should have a little oval disc in your manufacturers package that will spread the pads to the correct width of the rotor (1mm greater). By doing this, you will move the appropriate amount of fluid to the caliper. Your lbs should have done this prior to sending out the bike.

    If the brakes feel spongy after this procedure and there are no leaks, there is not enough fluid or air in the system. Tilt the bike up and add some fluid to the lever. If that does not work do a complete bleed.

    Hi,

    i had / have the same issues on my new Enduro Comp 2014.

    An Formula employee answered to this issues here (in german):
    Specialized Stumpjumper FSR Comp evo 29 | MTB-News.de
    Post #21

    The poor brake performance can come from a sticky seal on the piston, due to long storage.

    He recommends mobilizing the pistons, just did it and it works like a charm:
    - remove brake pads
    - insert a wrench (i used a 12mm thick steel) between the pistons, so they can't come out
    -pump the pistons till they comletly hit your "tool"
    -now push the pistons back with your "tool" (takes some force),
    Don't use something sharp like a screw driver...!!!

    worked for me, great brake performance, defined pressure point.
    But the damn rear disc makes me crazy, >15km/h it begins vibrating like hell, sounds like i'm riding with loose tin cans in my bag...
    And when it's wet... every braking, they know i come miles away.
    Cats and dogs hate me ....

    Tuesday i will change the rear disc & pad, hope this works.

    I've also had "the problem" and solved it by swapping out the rotor for one of these... https://www.sram.com/avid/products/centerline-rotor. No other mods done, and quiet and blissful riding now!

    I have a friend who purchased a new Giant Trance 27.5 just shortly after I got this Stumpy HT EVO (both from same LBS), and his came with some Shimano M395 or 396 brakes. His rear developed a very slight leak recently and Giant/Shimano replaced BOTH of his brakes with SLX for no cost. He just had about a week of down time.
    Now I wonder why SBC/Formula could NOT back up their product/consumers in the same fashion... ??

    Swapped out the c1's with XT's from specialized for $50. I believe it pays to have a good relationship with a good shop, they took care of everything.

    Thanks Specialized for standing behind you product specs.

    Incredibly happy! Big upgrade from my rigid SS. I've only had it for a few weeks and braking power has improved with each ride, but it has developed the same vibration issue. Bringing it to my LBS on Friday and will hope for the best. My LBS has been top notch so far......

    I bought my 2014 Camber Comp Carbon in June and put around 500 miles of Mt Tam riding on it and my Formula C-1 brakes have worked flawlessly from day one. I replaced the pads at around 300 miles, but everything else has been spot on. I'm also a hefty 205 pounds so the brakes are working overtime for me. Maybe I just got a lucky pair?

    My formula brakes on a 2014 stumpjumper evo had issues until I bled them, since then they have been flawless. My lbs did not bleed them properly, brought it in twice with issues, then gave up ordered a bleed kit and bled them myself. Since then I have put about 1400 miles and have only had to change pads.

    I'm glad to hear mine aren't the only ones that are working well. I let a good friend of mine take my Camber Carbon out for a day and he came back and was really impressed with the brakes - I guess I got lucky to have them bled correctly when I bought my bike.

    After disconnecting the hose from the clip on the seatstay the vibration is gone.
    Now, after pad replacement and proper alignment they work fine and I find no reason to replace them.

    I have a Specialized Stump Jumper Comp FSR 29er. If I decided to replace the Formula C1 disc brakes and go with Shimano Deore or XT, will I also need to replace the disc rotor? Or will I just need to have different adapters to mount the Shimano brake system.

    Also, does any one know where in the US, are the best online prices for these Shimano brakes systems?

    Thanks in advance.

    If you do get rid of your C1's a friend of mine might buy them from you - he's looking for a set.

    You can run the old rotors if you don't have a ton of time on them.

    You will also need Shimano specific adapter(s) for the given rotor size.

    I have been riding C1s on my Carbon Orbea with no problems now for almost a year. Front brake grabs quick, I could probably adjust the lever a little. Back brake takes a little longer pull. I can easily lock the wheels up with one finger. Pretty light too at 337 grams. I had Avid Juicy before and the always leaked fluid... Maybe your LBS guys did not set them up correctly to begin with.

    Rear brake feels a little inconsistent but vibration and noise are gone.
    I have the SJ Comp 29er and yes removing the rear brake line clip from the seat stay worked (amazingly). And using the existing flat head screw I then devised a different clip that did not hold the brake line tight against the seat stay... and after riding the noise came back but not as loud, still not good. I did not feel comfortable leaving the brake line free to roam so to speak so I loosely looped a zip tie around the brake line and the seat stay. Works great...no more donkey noises (vibration) and it brakes well.

    i took my bike back a long time ago and the lbs said he returned the brakes to the company for them to check em out. i thought they would be replaced but the same ones just went back on and it seemed like it was sortof fixed. i hadnt ridden my bike in ages and the back brakes lever once again falls to the handlebar and it seems like it is leaking fluid again like originally. sick of stuffing around i want to replace the brakes with XT's. are they a direct replacement or will i need some sort of adaptors?
    ide take the bike back to the shop but ive had the bike for longer than a year but barely done 600k's on it.

    I had all the same issues on my stumpy comp too. Plus both failed only a year later. The left piston would get stuck on front and back brakes. Terrible brakes.

    Yes, terrible brakes. Both died (seals gave out) in about a year. I thought they were going to be decent brakes because Formula seemed to be a pretty good company and I thought they wouldn't put out something that was absolute crap, but using the brakes definitely proved otherwise. Among the worst features was the pump downhill. I think the heat-expansion valve or reservoir was set up to only work when you would release the lever, but by that sometimes your fluid had heated up significantly and the engagement point had moved way out. If you released them twice or so they'd be back to "normal", but a widely changing engagement point and the "pump" as they heated up was way over the top. Into the dead brakes pile with my avids.

    Mine worked fine for a year - but I got a deal and replaced them with Zee brakes and boy what a difference!

    Is there a definitive answer as to whether the XT or SLX is a direct replacement other than the shifter rings you need? Can I use the same rotors/pads if they have relatively low miles on them?

    Yes direct replacement no adapter needed... you mention pads though? you cant use formula pads with shimano brake calipers.
