     MTB brakes are crap all round.

    Really? why d’you think so? I mean, I know a good chunk of threads on here are “How do I fix this brake problem” but given that there are literally millions of perfectly well functioning brakes out in the real world, I think “crap all round” is a bit wide of the mark, no? I mean personally I’ve never had an issue with any brakes I’ve ever owned, and that’s obviously going to sway my opinion, and some have been better than others, but mechanically, they’ve all worked as they should from Hope, Shimano and SRAM. Given how light and compact and powerful they are now, “Crap” seems a bit harsh.

    It’s like cheap over servo-assisted brakes that ‘feel’ powerful because they bite as soon as you breathe on the brake pedal, vs a set of non servo assisted 6 pot callipers. I know which I’d rather have on a track car.

    Also, more power is (almost) never a bad thing, a bloke with a 500bhp car doesn’t say no to an extra 100bhp… 😀

    I probably won’t buy but only because my tech 4 V4’s are perfectly fine.

    Quite likely I will be tempted to get some for my E4s if it looks like they offer a genuine improvement and I have cash burning a hole.  This is despite the fact that my E4s are perfectly fine, just not as good as some of my other brakes

    Very little of this has anything to do with the brand. Think about it. It’s some fluid, a plunger pushed by a lever, and a piston pushing on a disc. What magic can you really inject?

    With car and truck brakes you run out of tyre adhesion long before your run out of brake power. That is not the case with mountain bike brakes.

    Those little details of design can make a big difference to performance. Probably the biggest design issue is that they are operated by human hands which puts lots of constraints on the lever and the master cyclinder design.

    I have more sets of shimano brakes sat useless in drawers with either jammed levers or calipers which leak fluid all over the pads than I do do fully functioning hopes which are being used on various bikes with no issues. Think I’ll stick with the hopes 🙂.

    MTB brakes are crap all round.

    wait what?

    of all the moving parts on both my bikes, the (hope) brakes cause the least amount of worry. Change pads when worn, and they go years without maintainence. I’ve had the rear brake serviced once after 3.5 years of use.
    for comparison, in the last 6 months I’ve changed suspension bearings, hub bearings, adjusted the gears twice, serviced the fork, trued the rear wheel… to say nothing about droppers!

    I previously had shimano, fine when new, got that “wooden” feeling at some point on an alps trip, nveer recovered. And I’d be lucky to get a year out of a set of rotors.

    And before that, Avids, which would fail if you turned the bike upside down, and would randomply pull to the bar mid descent.

    The problem is that a brake that has good power at high speed cannot have good low-speed modulation, and vice-versa. The first disk brakes I had were Hayes HFXs, which were the mainstay of DH racing 20 years ago. I ran them with an 8″ front rotor and metallic pads, they were ferociously powerful but had terrible modulation. The first time I rode with them, I fell off in a tight corner because my little dab on the brakes brought me to a screeching stop.

    After that, Shimano came out with Deore (2-pot) and XT (4-pot) hydros. They had much better modulation than the Hayes and basically put Hayes out of business.

    People who think that current brakes are crap really should try riding some bikes from the 90s. I’ve used Hayes, Avid, and Shimano hydros. They all work well when they’re set up and bleed properly. They can all be a bit tricky to bleed sometimes, especially rear brakes, and sticky pistons are an occasional problem for all of them. Once they are set up properly, they just work fine.

    it is for me. easy wheel locking or OTB even on tarmac with sticky tyres

    The other issue is I have V4’s on 2 bikes, so would need 2 sets, couldn’t be doing with mis matched brakes! 😀

    Glazed pads would be my first guess.

    Avids, which would fail if you turned the bike upside down, and would randomply pull to the bar mid descent.

    This happens when you have air in the master cylinder reservoir. They have been underfilled and/or not bled properly. This can happen to any hydro brake that has air in the master cylinder reservoir.

    I’ve had a couple of trips OTB on dry roads when cars turned in front of me. The limiting factor for rear brakes is grip, for fronts it’s either tyre grip off-road or going OTB on-road.

    You can put the pads in backwards in truck and still have enough brake power to stop a truck. (I know this because the company i worked for had to change pad design to stop fitters acidentally putting them in backwards)

    Compared to off road surfaces tarmac is a much more predictable braking surface. Which is another major design constraint of mtb brake design. It is no good claiming your brakes are crap if you don’t have the correct tires for surface you are trying to brake on.

    One of the key points which you metioned earlier is setting up the brake properly. The running clearance between the pad and the disc makes a very significant difference to how well the brake works. Automotive calipers can float which helps this. MTB calipers don’t which means it is even more important to get it right.

    Front brakes do way more work, its why older cars used to have discs on the front and drums rear. the limting factor of any brake is always tire grip.

    I rode with him this weekend and his his brakes were frankly terrifying.

    There’s definitely an issue with them, in that case. Do you really think we’d all be riding around with brakes that don’t work? We aren’t all that stupid.

    I have Hope and Shimano on my two most used MTBs. The Shimano feel sharper, but that’s not important – what’s important is when you are going fast down something steep and need to stop as quickly as possible. This depends on heat buildup at the pad, and the two sets of brakes I have both perform the same in this respect.

    I think that Hopes can suffer from micro-leaks of fluid maybe, as they are somehow more susceptible to contamination. When I clean my bike I put a squirt of bike cleaner in the caliper and hose it out, this keeps everything running sharp. But before I did this there were issues with contamination, although I am talking 20 years ago now. But Shimano aren’t immune to this, I had to do it on them before yesterday’s ride.

    Oh and my Hopes are Mono Minis from 2007. Recently changed the caliper seal because I could, because the parts were available. That makes them pretty cheap.

    it is for me. easy wheel locking or OTB even on tarmac with sticky tyres

    This is also misleading since it’s not the most important usage cycle for hard braking.

    I think that if you don’t clean your brakes they become contaminated, they get worse, and you don’t necessarily notice.

    Also not grabbing the brake leading to instant lock up. As more weight transfer happens (especially on tarmac) the bigger the tyre contact patch and the more grip you have. That’s one of the first things you learn when riding a motorbike, the same applies to cycles on the road and off road. The rear brake is just a passenger under proper heavy braking.

    the limting factor of any brake is always tire grip.

    On an MTB, it’s fairly easy to OTB in an emergency stop on road or on steep descents in the dry. In that case, stability is the limiting factor because you have more front tyre grip than you can use. This doesn’t happen in a car because their center of mass is lower and they have a much longer wheelbase. On an MTB in wet or loose conditions, tyre grip will give way before you OTB. In that case, the limiting factor is tyre grip.

    The first guy in my riding group to get disk brakes bought a DH bike with Hayes HFXs, but had them set up U.S. style. Another guy was keen to try them and tried to do a big rear wheel skid in the carpark, not realizing the brakes were reversed. He just grabbed a handful of front brake and popped straight over the bars, looked very painful. That big grippy DH tyre did not lock up, it just gripped and gripped.

    Really?!! On both my bikes it’s dead easy to skid the rear and if I just yank on the front I’ll go over the bars if the grip is good or I’ll skid out. I don’t believe I’m the only rider with good brakes and finger strength.

    I’m not a Hope fan and especially hated the Tech 2 level, but I bought a bike that had Tech 3 X2s on it and they were just bloody lovely to use compared to my XTRs (m988 and M9020). Yes, they didn’t have the outright power, but I can just pull a little harder, rather than be overservoed. I fully intended to sell them, but given how nice they felt and given that I’d gone through 4 callipers in 2 years (3x XTR, 1 BR785) and was just waiting for the others to die. I swapped them all. I agree that they’re fiddly to setup right, I agree that bleeding them is a PITA, I agree that they’re expensive and lacking immediate power, but they are nicer to use, and completely unambiguous in operation. Something you absolutely want in a brake!

    it’d be ace if these new levers brought their performance up to be comparable with sram code rsc. I’d have a pair like a shot. Problem is that you just cant trust any reviews as braking performance is so subjective (as proven by this and every other hope brake thread) .

    I guess if the hope fanboys start saying they’re too grabby then that would be a good sign….

    I’m not sure I could skid the front on either of my bikes, Hope or Shimano. I could go OTB though if I just sat there like a sack of spuds and didn’t get my weight back. But that movement is so instinctive I’m not sure I could actually brake hard without doing it.

    Saints, the only brake i could lock up the back wheel with.

    Actually my favourite was the C2. Immense power, just not suited for long runs, but outwith dh thats uncommon. 1″ pistons and a solid non flexible lever.

    Well I’ve ridden SRAM, admittedly not since the original Code, and they were ok initially but maintenance heavy with a habit of needing a bleed before they’d work.

    I rode the old Hope Mono Minis and they were no better than ok.

    I generally ride Hope X2, M4 or E4 these days (variety of different levers on them) and I like them. Very dependable. Would I like more power? In a brake with great modulation, yes of course, because I get to choose whether I use it. Do I need more power? No, not really.

    I recently rode Shimano 6000 2 pots. No more power than an X2 and less feel.  Quickly bought some Hopes for that bike.
    Kept the 6000s and my son put them on his parts bin bike. He doesn’t like them as much as the ten year old M4s or newish X2s he had been using. Described it as you put them, the brake comes on, you pull a bit more and nothing more happens. I think he means, where my modulation gone?

    Others will like the Shimano digital feel. And I hear SRAM brakes are not as temperamental as when I last had them.

    Reverse bleed works really well and is probably the easiest bleed on any brake.

    Not what Hope recommend, but I see a lot of bike shops doing it on Hope.

    Hopes seem like they do the job but there are like 4 people in my riding group who have Hope brakes and every single one of them squeals and squeaks in the most uncomfortable high pitched sound, that really puts me off them. I’ve seen lots of youtube people with Hope brakes also have the same sound, I wouldn’t be able to put up with it if I had it on my bike.

    The problem is that a brake that has good power at high speed cannot have good low-speed modulation, and vice-versa.

    Ehhh… My ancient Formula The Ones, and some of the SRAM Guides and Levels, prove this wrong. And no doubt loads of others but those are the ones that I’ve got most experience of. Power and modulation aren’t mutually exclusive at all.

    But I think like people said earlier in the thread some people conflate grab with power, so brakes that have both good modulation and good power split opinion. I can definitely understand why a lot of companies, when they make a powerful brake, also make it unsubtle. Can’t think of how many professional reviews I’ve read that complain about a lack of initial bite.

    In the end it’s a matter of taste- I did’t like my Saints at all on the DH bike, and went back to my lovely The Ones, but I reckon that puts me in the minority.

    Reverse bleed – drain the master cylinder, squirt new fluid into calliper bleed port while making sure the hose is the highest point on the calliper. Drain master and repeat. Keep doing it until the fluid at the master cylinder is clean and bubble free.

    Done with either a long hose on the syringe to the calliper, or with two people it’s an almost continuous process. Great way to teach your son how brake bleeding works.

    I did not word this very well

    The power of MTB brakes is much closer to the tyre adhesion limit, it is why they are so sensitive to contanimation, heat and choice of friction material. Yes you can lock your wheels but can you do it in all conditions and at all speeds? probably not.

    Automotive brakes can run red hot, with oil on the discs and low quality pads and still bring you to a stop because they have orders of magnitude more brake torque than is required to by the tyres.

    I haven’t driven a car with unservoed brakes in a very long time – but isn’t that the big difference?

    When a car skids it doesn’t fall over and now we have ABS they don’t really skid. On a MTB we spend a lot of our time on the limit of grip, both braking and cornering.

    Hopes are really simple to bleed. Far easier than the shimano, Sram and Tectro I have also bled. No special kit needed – just a bottle of fluid and a piece of clear tubing and an old jam jar
