    good to hear that..

    I got some 1set of 4pots on goodridge alu fittings too.
    fitted nicely and had fitted plenty of them with other brakes too (about15-20 sets) and only 1 breakage so far.(crossing my fingers)

    only 2/5 weight of the stainless stain ones..

    i get some pictures too...

    Nice set!

    I have a set of m755 with the m756 levers. How are those dangerboy levers? I have been on the verge of getting them for some time.

    I love my 4pots (except for the rather high cost of adapters).

    I have 4-pots front and rear on both my bikes, and they won't be leaving anytime soon.

    One set is from the first release- 2001? And still going strong. New hoses and fresh fluid/pads are the only upgrades on that set. Amazing how much abuse the levers take! They are still slop-free.

    I have yet to find a brake that compares, unless you spend 3-4x as much... and even then you don't have the small parts availability you get with shimano.

    I went with hope hoses and straitline levers on my AM bike, I liked the brakes so much after 5+ years it seemed right to pimp them up a little bit. I also replaced all the bolts on the levers with stainless steel hex fittings from my local hardware store. They should be good for another 10 years at this rate!

    So I finally did it.
    I ordered a brand new, unused set of 755xts with 756 levers and standard hoses (will do it for the moment). Ill get some 160mm rotors, but I wont use them. Ill directly get some 8" rotors.
    And Straitline lever blades of course.

    I am coming from a set of 2007 Magura Gustav Ms and before Ive been on Deore 525 and Saint Discs (Straitline levers on the Saints, too)

    I loved the Saints, especially the Straitline levers, then got upgradeitis and bought the Gustavs (I work at an LBS parttime, so I get nice deals) and while the braking power is nice and consistent I hate the lever feel of the Gustavs. 2finger or 4finger blades, both dont work with my hands. Alsoat 149lbs, I dont need that much power.
    So I always loved Shimano parts for their second to none finish and excellent quality control. And I always wanted a set of the 755s, just never had the cash.

    I will sell the Gustavs for sure, even if they are top notch brakes and a thing for themselves, just not for my hands

    Now it was either, a set of 2008 Codes or get some 755s and pimp them.
    Seeing quite some defective Codes or little issues with them, I went for the 755s.

    Ill get an 8" adapter for my Fox 36 PM fork and an IS to IS8" Adapter for the rear, does anyone have the numbers?

    Which rotors should I get? Just some XT8" as they are cheap or something else?
    I always felt that the 6bolt XT rotors had a bit less braking power than the newer centerlock XTs with the curvier pattern.

    Also the Hope floating discs for the M4 look killer, the M4s even use the same pads, should be a nice combination. Do you notice any better heat resistance with the floatings? Or is it just optical bling?

    Id sell them for a good price, but I live in Europe. I guess shipping would be too expensive?

    Its a 210/190mm f+r set. Comes both with a Post Mount and a Boxxer adaptor for the 210mm front disc. long hoses and brilliant condition. Also comes with the 2 and the 4 finger levers and a bleeding kit and the manual and some shims. Id sell them for 500$ (plus shipping), mint condition. Pads are just bedded in.

    Similar, but not quite. The XT uses mineral oil, I believe those two use DOT fluid.

    755 with XTR DC

    Yep, I had such a set two years ago on my Kikapu - 755 4pot paired with the '04 XTR Dual Control lever/shifter set. Haven't seen anyone else doing it You did see 755 levers paired with XTR callipers (for those who didn't like DC) but not the opposite. Anyway, it was doable and quite nice. Two years without single issue.
    I switched to Hope M4 for the BLT though - a lot more power but I use 8"/7" rotors f/r

    I was hoping someone had both the 755 and the Mono M4 to know how they compare.

    Anyone have any tips on how to get 4 pots to work with either 8" PM direct front or rear mounts?

    I've got a Trek Session 10 and the rear mount is 8" PM direct. Maybe use the smallest Shimano adapter and a 220mm Formula rotor?

    Yeah, you'll have to use an adapter and up the rotor size. The minimum increase is 10mm... so that'll bump you to 213mm. And you can shim out the adapter with 3.5mm of spacers.

    I thought I was the first and last person on the planet
    Anyway my worries were if the pistons were identical in the 755 and xtr lever units in terms of volume/stroke. I wasn't worried about fittings/cables and other stuff, bacause shimano makes them homogenic. But there was no way to check it other than by doing
    All came out ok.
    Ypu'll probably see sh!t on these photo's in terms of 4pot XT's but it;s all that's left.

    755 vs M4

    Quote Originally Posted by Jerk_Chicken

    JC - I can try to compare the two sets but I had 755 with 6" rotors and the M4 uses 8"/7" now so you have to filter what I state.Plus they were never on the same bike. the wheels are the same though and tire setup is simmilar to what I had in the last few months of the Kikapu. And my better capabilities are equaled in the weight gain 200lbs now and used to be 180.

    OK, here we go, my shy $0.02:

    1. Modulation/Power
    I'd say the M4's have way better modulation and are ALOT better in dispatching heat. The heat dispatch is better thanks to the size of the rotors and the alloy spider - at least that's what they advertise Anyway the 755's were geting realy hot during long descents and the M4's don't.
    I wouldn't say M4's are a lot more powerful and that's with the bigger rotors taken into acount (I think they'd have about the same bite with equal rotors). I was hoping m4's would be stronger. Can't use it with one finger realy. None of them.

    2. Design/maintance
    The 755's with the XTR DC had a kind of 'flexy lever feel' (thanks to the DC)
    755's with the original levers were harder but the levers did tend to get loose and clunker in the rough stuff without any hope to fix that - M4's have a nut to tighten there.
    755's use Mineral oil and that is easier if you like to mess with your setup. M4's use DOT which on the other hand is supposed to handle heat better.
    I used the 755's for 10k miles. I never, ever had any problems with the 755's in terms of taking air. And the metalic pads lasted ages there!
    I use M4's for a year now and just under 4k miles - no issues whatsoever.

    3. Looks/bling
    judge yourselves but I say nothing looks better than Hopes. 755's made the kikapu look like a motorbike but that was in 2004

    And don't forget, which you likely know, the M4's use the same pads. In fact, I use Shimano m03 metallics in mine.

    I've posted elsewhere in the past along the lines of the cost factor making them a no-brainer. I do like the Hope compounds, but the Shimano is close, especially at $10 less per set. Springs are bent a bit narrower on the Shimano models, but it's still functional. I have a bunch of sets, along with some Hope golds, and some Ritchey metallics that were on Fleabay for like $15 shipped for 2 sets.

    Impossible to find anything in that price range in Poland. In fact, when you compare prices of bike stuff in US and Europe, you get exactly the same numbers but in different currency That's sad, everything here is 30-40% more expensive. That's why I buy most stuff in the US - makes sense even though I pay for shipping.

    btw are the gold hope floating rotors a special edition or are they available in multiple colors? Mine are just grey and gold might suit my ano orange BLT
    They didn't give me any choice by purchase.

    Yes they do come in different colours. Here is a link to some of them if you navigate this site and look around, they have other things too. Just as a means of looking at what they have ane not necessarily buying from this site...!?

    SITE

    Break kits

    Rotors

    Somebody state if this site is a good one to purchase from because I am unsure. I think it looks good (not aesthetically though) and they have a GREAT sellection.

    thanks guys,
    I got my floating 8"/7" as an upgrade from std one piece and received the former M6 model (not wavy). There was no option to it. I might just take a shot now with the gold ones. They seem dark enough - has anyone paired them with CK mango hubs? I'll probably have to post a separate thread on this one.

    Hello again!
    I am thinking of "maybe" upgrading my 4pots with some Goodridge lines.
    Is there a noticable difference in lever feel?
    I`ve got some Straitline levers and HAYES V8 rotors, so I think I could also go ALL THE WAY, too.

    You won't notice a difference in feel. The only way is if the system needed to be bled to begin with. I replaced the stock hosing with steels a couple times to find no difference. These brakes were well maintained with recent bleeds.

    Just get the Hope hoses (made by goodridge)- you can get them through seller monkamoo on eBay. The reason to get the hopes, "kit #0" includes fittings you may need to pair newer shimano levers with older calipers, or replace the older 90d. banjo at the levers with in-line connections.

    I have two sets of M755's, one with hope hoses and straitline levers, the others are stock. I did feel a subtle change in feel when going to the hope hoses, but there are so many variables it's hard to give the hoses credit. A good upgrade though I think, certainly more durable than the shimano hoses.

    Ok, so Ill just spend the money for some lift tickets, or save it until I rip off a hose.

    My Float conversion turned out BEAUTIFUL btw. I just dont have toooo much spare time at the moment to post some pics and make a write up.

    The Float uses the travel very good actually, pretty astonishing...

    Oh man...what a nob I am. I just noticed that you pointed out my typo on "break" to "Brake"...ha ha ha. Wow...I'm slow but I get there in the end...usually, well ok sometimes!

    Just smacked my M4's on the XO and boy oh boy, don't they rock. Back to back, apart from oil choice, I love my M4's to that of my XT's - as classic as they are.

    Yep, XT 4 pots are the way to go. I'll never give mine up. (Unless the new 4 pot Saints are really that much better.)

    Speaking of the 4pot saints, they are still a 2 piece affair though, with some weight reductions. Still be interested in how they perform though. And as much as I love my XT 4pots, I really hate the massive nipple...(also related to the m4's) This is where I like Avids version of the internal nipple, or bleed port as such.

    Speaking of lighter weight, I replaced all the bolts on my XT 4 pots with titanium. Saved a bunch of weight right there.

    The new Saint 4pots seem to have a higher leverage ratio, maybe an even "stronger" servo-wave.
    I expect them to be not too expensive, Shimano prices are really, really low over here in Europe. All those OEM-online sellers make Shimano retail prices obsolete.
    So ill just get a front brake and test it against my 755s.

    But I think they are not available until August or something.

    Yeah a bit later I'd imagine...I am going to get the Rr Mech though, very keen to check that out.

    TI Bolts...where did you snap up those beauties, are they appropriate...!?

    I got 'em at hyperbolts.com. You need 12 -- 4 for the front caliper, 4 for the rear, and 2 each to mount the caliper to the frame/fork. I've been using them for the past year with no problems, and 60 grams or so in weight savings.

    Sweet...thanks for the info aswell.

    60 grams is substantial in terrms of brake (BRAKE, he he he) weights as such. Consider them on my "To do and get" list.

    NICE!

    Do you have exact numbers of the needed TI-bolts? M5x10mm or something like this
    Seems like a nice upgrade, add some TI-rotor mounting bolts and youre at about 90g weight saving, without performance loss Id think!

    Greetings Znarf

    Shoot, I don't. I do know that the diameter of the 4 for each caliper are the same, but two are maybe 20mm, and 2 are 18mm. The two that mount the caliper the the frame are obviously bigger. You can figure out the head diameter by seeing what hex wrench fits, and measuring the length can be done without removing any bolts. Should be pretty easy...

    Has anyone tried the new XT servo-wave levers with the 4 pots? I have a set that I've been hanging onto for a special occasion. I am thinking of replacing the Martas on my Sultan with my 4 pot calipers and the new XT levers, if they're compatible.

    Aparently the new servo-wave levers use too high a pressure for the 4 pot seals so it's not a good idea to use them.
