Item # SHI008F


Shimano’s new Deore XT Disc Brake is part of Shimano’s sexy new M8000 gruppo. The new brake offers a few subtle refinements for a reduction in weight and a sleeker look. The redesigned brake features a new lever with an integrated master cylinder and, of course, a menacing black ano finish. It frees up a bit of real estate on your dashboard with a narrower clamp, and its compatibility with the latest generation of Shimano's I-Spec design, I-Spec II, means that it can also anchor I-Spec II shift levers, saving even more space by attaching both the shift and brake levers with one clamp.

In addition to the excellent power and modulation, the XT Brakes provide easy adjustment to keep your fingers happy and intuitively in control. There's also a tool-free reach adjustment that you're able to dial on-the-fly, along with a free stroke adjustment that lets you determine lever-blade-to-travel before pads make contact with the rotor.

Also, Shimano reworked pivot location so that the arc of the lever mimics the natural movement of fingers for enhanced power. Servo Wave technology comes into play here in order to adjust piston travel relative to lever travel. As you squeeze on the brakes, the gap to the rotor quickly closes, then slows to permit predictable modulation. This allows the pads to sit further from the rotors at rest for less chance of drag. The calipers house a 22mm ceramic piston for inspiring stopping power, and Shimano uses a banjo fitting for the hose attachment at the caliper. The calipers also employ Shimano's Radiator Pads that have integrated fins in order to dissipate heat and to reduce fade on long, hot descents.

The Shimano XT BL-M8000 Hydraulic Disc Brake has hinged, split clamps for easy mounting. It comes as a pre-bled lever/caliper/hose assembly and it’s complete for each end of the bike—except for rotors (sold separately). Shimano XT Brakes will work equally well with XT Ice Tech Rotors or standard XT rotors. Please note that this brake is sold separately as either Left/Front or Right/Rear.

    After fighting SRAM Guide brakes for months I made the switch and couldn't be happier. These are dependable and predictable offering great modulation. Easy maintenance and setup is perhaps the best perk of these brakes.

    Super reliable

    • Familiarity: I've put it through the wringer

    The major benefit to these brakes is that they are reliable. They generally run quiet and are low maintenance. There is no shortage of braking power; these are strong brakes. My only complaint is the modulation. They feel a bit grabby to me. Some people like that feeling though so it does come down to preference. The bleeding procedure is simple which is nice.

    Reliable brake

    • Familiarity: I've put it through the wringer

    They are very reliable so you don't have to worry about issues or failures. My only complaint is they don't have much modulation which gives them more of an on or off feel.

    The best brakes on the market!

    • Familiarity: I've put it through the wringer

    I have been through 4 sets of SRAM Guides, all of them have failed. I finally switched back to XT, and I have no idea what took me so long. Do yourself a favor and buy these brakes, they are easy to setup, rarely fail, and work tremendously.

    Shimano Breaks

    • Familiarity: I've put it through the wringer

    You should only buy these on your bike. They are the best and I will always have XT breaks.

    Killer Brakes

      Love the simplicity and quick reaction of XT brakes. They are fairly simple to maintain as well. 5 Stars!!!

      Best brakes I've had

      • Familiarity: I've used it several times

      What to say here - these XT's are as good as I've had. Over the past several years, I have had the terrible Avid Elixir 5's, (bleeding is a regular occurrence, and it's difficult to get right) swapped those for the predecessor to these - the XT M785's. Loved those. Had the Avid X0 Trail brakes on another bike which worked well, but never had the modulation that the Shimanos offer. These M8000's are great. I shortened both front and rear hoses easily, bled them, and went riding.

      Great adjustability, great modulation, and they are super reliable. Easily the best investment in the MTB brake world right now on a pure performance per dollar basis. Great price and service from Backcountry.

      Best brakes for the price-point

      • Familiarity: I've put it through the wringer

      Shimano brakes are simple, cost effective, and easy to maintain. Newer, sexier options are available but these tried and true brakes just keep working!

      These brakes are worth every dime!

      • Familiarity: I've put it through the wringer

      I cannot get over how great these brakes are, especially when paired with the Ice-tech rotors!.
      I run these brakes on my 29er and I do alot of hard riding on Rocky terrain with steep hills, and I relie on my brakes alot. and these brakes will lock on a dime but u can also feather effectively!

      if you ever experience squeling with these pads, nail on the brakes at around 20 or so mph, two or three times, cleans it right up.

      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.


        • Familiarity: I've put it through the wringer

        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.

        *Opinion* Best brake for the price.

        • Familiarity: I've put it through the wringer

        Easy to set up with exceptional lever feel. I even prefer the over xtr models.

        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.
