    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.

    Based on a sampling of how many failures?

    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?

    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!
