Building off the smashing success of Shimano's XT BR-M785B Disc Brakes, the Shimano XT BL-M8000 Disc Brakes offer enhanced ergonomics with their sleek integrated master cylinder and simple integration with I-Spec II shift levers. Not only does this improved design shave precious grams, but it also frees up valuable real estate along the handlebars, which is always a positive with the ubiquitous use of dropper posts on modern trail bikes.

Sero Wave technology delivers reliable stopping performance across widely variable trail conditions and riding disciplines. This technology improves brake engagement by closing quickly upon first squeeze, ramping up power after initial engagement for improved bite. 22mm ceramic pistons inspire riders to push their limits with gobs of stopping power at a moment's notice. Shimano's Radiator Pads disperse heat on shuttle runs and lift-accessed downhills, preventing dreaded brake fade on lengthy descents. Tool-free reach adjustment dials in a custom feel for precise trigger actuation.

The Shimano XT BL-M8000 Disc Brakes come with everything needed for installation. This brake kit works with Shimano's XT and XT Ice-Tech Rotors for reliable stopping performance in all conditions. Hinged, split clamps allow for easy mounting. The pre-bled lever/caliper/hose assembly is ready for installation on your favorite trail bike.

Great brakes! Requires a lot of setup

    Yes, these are excellent brakes! But you probably already know that.
    I ride a Medium MTB (Niner MCR) and the hoses on these brakes were waaaaaay too long. I knew they'd be longer than what I've got, but not +12" longer (the front brake wasn't so ridiculously long, but the rear was 16" too long). So after you purchase these brakes, go to Epic Bleed Solutions, buy their bleed kit, hydraulic hose cutters, and 8mm spanner. I recommend them because they also have a detailed step-by-step on how to cut your new Shimano brake cables (hopefully) without needing to bleed your brakes. But if something goes wrong, you will need to bleed the brakes, so have a kit on standby. Anyone with the right tools can cut the hoses, it doesn't take special skill. But it is tedious, and anytime I'm risking adding air to my hydraulic lines I'm sweating bullets.
    Bottom line, excellent brakes for a good price! But these pre-bled brakes are only plug-and-play if you're a big rider.

    It used to be that XT brakes were pretty much the only trustworthy brakes available. Nowadays there's actually a lot of great, reliable options. However, great to see the XTs are staying relevant as well. Same old reliability, feel, and power as always. They definitely do not have the best modulation out there, but plenty to work with once you're used to them. Like any hydraulic brake they take some maintenance to continue to work well. If you own ANY hydraulic brake I would highly recommend investing in the bleed kit and taking the time mastering the bleeding process, it's worth it.

    Pump em to work

    • Familiarity: I've put it through the wringer

    Started having problems with them where they pulled all the way to the bar on the first stroke so you had to pump them to engage solid! Easy fix right just needs bled, Did that and new pads and they go to the bar and you have to pump em-now the bike shop talked to the Shimano rep and he says that's ok-the shop worked the Shimano forums and they are all complaining about this problem with these brakes. I cant recomend these now that Shimano has a design issue and they admit it.

    Yet another 5 star

    • Familiarity: I've put it through the wringer

    Been riding mountain bikes at a high level for 23 years...tried every cool brand made for every part of the bike...In the end I also learned not much reason to buy anything other than Shimano XT for any drivetrain/brake part on the bike. They work flawlessly, awesome quality, always improving...and these new xt brakes? Lever perfect size and fit, the new clamp allows for attaching other things to the bar...and of course amazing braking power.

    Awesome brakes

    • Familiarity: I've put it through the wringer

    This brakes are bombproof. Feel great, look great, tons of power. Not quite as much modulation as SRAM Guides, but definitely more durable

    What is the length of the pre-bled hoses for both front and rear?

    Hi Cameron. The rear brake cable is 1,700mm long, and the front cable is 1,000mm long.


    • Familiarity: I've put it through the wringer

    I made the switch to Shimano XT's 2 years ago and won't go back to anything else. I've experienced nothing but reliability and confidence in these brakes. I bleed them once a season and change then pads out when needed, and that's all I've had to do. The price is reasonable for how long they'll last you and they look pretty cool up on the handle bars too. Levers are a good size and make it easy to engage with a single finger and the response time is incredible. I would highly recommend these brakes to most any mountain biker out there.

    The standard for a reason.

    • Familiarity: I've put it through the wringer

    Set up was easy, but I did have to trim both front and rear hoses. They feel great now with nice firm level-feel and outstanding modulation. They feel about a million times better than Guide R's and feel the same as Deores, but look a bit sleeker. I would buy them again in a heartbeat.

    pump the brakes bro

    • Familiarity: I've put it through the wringer

    I say that now but really brakes arent even necessary. I purchased these strictly as a back up in case my feet and head dont do the job.

    Shimano XT Brakes

    • Familiarity: I've used it several times

    Had the generation of XT's before and these look way sleeker. I love the modulation of these brakes and how the have a on/off feel. These brakes are great for cross country all the way up to all mountain and have even ridden them on my downhill bike.


      Been running these XT brakes for 3 years now. Replacement of worn out pads are extremely easy. I've never had any bleed issues with these. The newer finned brake pads are great for avoiding fade if you live somewhere this elevation.

      Unanswered Question

      Is an extra olive and insert included for shortening the cable? Is a bleed block included?

      So Good!

      • Familiarity: I've put it through the wringer

      These things just plain perform. I've had older generations and this latest as well. They have not let me down and in my opinion provide some of the strongest and best feel in brakes today!

      hi, can i buy just up portion( Hand portion)?

      Hey Pierre,

      The lever and calipers are sold pre bled and unfortunately they are not sold individually through us - don't hesitate reaching out directly if you have any other questions or anything I can help out with!

      Good Brakes

      • Familiarity: I've put it through the wringer

      I have an older pair of these on another bike. These are just as good and lighter. Easy to install with the clam shell clamp and super easy to bleed. Question is: do I get another pair for my wife's bike?
