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.

  • The most popular brake for self-sponsored racers
  • Predictable modulation empowers precise braking
  • Ceramic pistons reduce heat accumulation
  • Finned pads further contribute to cooling
  • Compatible with I-Spec II lever systems
  • Pre-bled lever/caliper/hose assembly includes everything you need

Gold standard (at bronze price)

  • Familiarity: I've used it several times

Coming off a pair of Hayes Prime brakes, these brakes are a luxury. They can be installed without a bleed, are so much temperamental, use standard fluid, replacement parts are easy to come by, and they don't brake the bank. A+ brakes. Excellent design and easy to service.

Reliable, affordable, solid brakes

  • Familiarity: I've put it through the wringer

These things stop. I love how easy they work. When comparing with other brakes I've tried, these are almost the easiest to bleed (my Hopes are easier), the best for reliability (SRAM brakes are notoriously unreliable), the best for quality per $ spent by far (Hopes are way pricey), and my favorite brake feel. My hopes require much more effort to stop than the XT brakes. Great, reliable brakes!

What a brake should be

  • Familiarity: I've put it through the wringer

These brakes work. Thats the best part about them. The pads sit straight in their proper position. They don't seize up. VERY easy to bleed and adjust exactly how you prefer your fingers to sit. The pull changes slightly over a continued downhill section but not enough to be an issue.

Stopped Me in My Tracks

  • Familiarity: I've put it through the wringer

I've been riding with these brakes on my all-mountain bike for a couple of years now. They have held up super well, despite my tendency to go down. They offer great stopping power, especially the 203 mm rotor in the front. The lever itself has a great feel under the forefinger, and is just the right length. I appreciate the ease of adjusting the lever in and out as well. Great buy.

Great break

  • Familiarity: I've put it through the wringer

The easiest to bleed and most bomb proof brake on the market for the most reasonable price, hands down

XT...enough said

  • Familiarity: I've put it through the wringer

Shimano XT...easy install, easy setup, easy bleed (yes you will have to at some point), mad stopping power. No reason to mess around with guides, did consider Hope. But save some headaches and money. Buy a bleed kit at the same time, learn to work on your's therapy, not cheaper but way more more fun.

Stop smart

  • Familiarity: I've put it through the wringer

The best brakes in the world are the Shimano XTR M9000 race series. Unfortunately, said stoppers cost big bucks, and as such, are out of reach for the every-man. The XT series brakes, particularity the latest M8000 edition, are an excellent alternative for XC racers, or for anyone in the market for a reasonably light, reliable, single-piston brake set. I've run these for three seasons now, and simply-put, they're great.

Great Brake. Pre-Bled?

  • Familiarity: I've used it several times

I paired this XT front brake with an XTR rear. It may be slightly heavier, but it has great modulation and plenty of stopping power for my cross country/trail style of riding.
I ordered the pre bled and left the hydraulic line intact because I do not like to bleed brakes. Unfortunately, it needed to be bled. I called Backcountry, who sent me on to Colorado Cyclist, for advice or an exchange. They told me to bleed the brakes, all I had to do was push fluid from the caliper to the handle. So now I have to buy some hydraulic fluid. That didn't do the trick, however, so I had to perform the full bleed procedure. Now it works well, but it was a frustrating process.

Great brake set

  • Familiarity: I've used it several times

I have both the old m785s as well as these. The new model has a much more linear feel to braking — versus the old which acts a lot more like an on/off switch. The levers feel very nice in hand as well.

Amazing Brakes

  • Familiarity: I've put it through the wringer

I’ve been using XT brakes for a while and the newest version are the best to date. From the updated caliper to the solid master cylinder these work flawlessly and look great. These also still use the same pads from the previous version. These are the best brakes you can buy for the price.

    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.
