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.

  • Familiarity: I've put it through the wringer

Love these brakes. Great stopping power in a fairly lightweight package. Parts are easy to find and bleeding them is a very straight forward process. Combine that with the price and these are hard to beat.

Good. Better than some. Not the Best.

  • Familiarity: I've used it several times

Good brake but I still haven’t found what I’m looking for.
I have ridden RSCs Ultimates Zees and these. These require less maintenance and tinkering than the Sram brakes but there is quite a bit of fade or irregularities in lever pull on longer descents when they are used more frequently.
Would I buy them again? Yes.
Are they my favorite? No.
Perfect on a XC or Trail bike. I may use brakes more than most, and given that I am 180lbs I like brakes that put down the power. I prefer Zees or Ultimates to XTs when weight is not an issue and when I’m going to be riding more downhill/enduro than trail/xc.

Awesome stopping power

  • Familiarity: I've put it through the wringer

These brakes have awesome stopping power and exceptional modulation. Shimano brakes are legendary for a reason and these are no exception. The mineral oil is also easy to bleed and work with if you are into bleeding your own brakes.

best choice

  • Familiarity: I've put it through the wringer

Of all the brakes out there right now, this has got to be the most consistently reliable brake. Great pull and consistent feel. Durable, lastable... able to last.

Best value stoppers for the price

  • Familiarity: I've used it several times

I recently bought these a pair of these stoppers for my santa cruz hightower LT and I love them! Coming from sram's top of the line guide brakes on my old bike, I actually preferred the XT's over the guides. The squeeze actuation on these are similar to an all or nothing type of feeling when braking. Its hard to explain but basically you get 100% braking force at one given point on the stroke and it has a good feel to it. Unlike the guide's, where you get a gradual hard stroke all the way through. Would highly recommend these brakes to a buddy of mine or anyone looking for the best brakes that won't break the bank!

Works like a light switch

  • Familiarity: I've put it through the wringer

Bought this after getting fed up with issues with my Sram Guide brakes. XT's are more powerful, levers have less free stroke (you don't have to pull the lever an inch before the pistons start touching the rotor), maintenance is predictable and consistent, but modularity is bad. 4 piston brakes offer a lot better modularity, lockup happens more frequently with these brakes.

Long story short if you don't care about upkeep and want something to work the same every time get these brakes. If you want the ultimate performance go Sram.

Tremendous Customer Service

  • Familiarity: I've put it through the wringer

Rear brake failed after 22 months of use. Had some issues off and on with it after the first 6 months, with some softness and a few trips to the shop to get it working properly. The front brake version of this still works fine. The 4 stars is for the folks at Competitive Cyclist who worked with me to replace it and ship it out a new one right away. That impressed me and I will remember that when I need more gear and components.

Yup, Another 5 Star Review

  • Familiarity: I've put it through the wringer

These brakes work first time, every time.


  • Familiarity: I've put it through the wringer

One of the best mtn bike brakes I’ve used that is a two piston set up, and not to mention Shimano is the most reliable mtn bike brake manufacture. These brakes have awesome modulation that is like a dimming light switch- not just an on or off switch. Paired with the ice tech rotors that help dissipate heat under extreme braking conditions, these XT’s will give you the confidence on any bike trail. For the price, it’s a worthwhile upgrade over the Shimano Deore or Shimano SLX brakes- especially to customize brake lever position

Awesome Upgrade

  • Familiarity: I've used it several times

I sent from M392 (something like that) to the XT brakes and they're amazing. I tried to get a little more power out of the Deores with Icetech rotors (and upping the rear to a 180mm) but after being dissapointed in the marginal gains I leaped to the XT's to compliment my new rotors. Always great service from CC and really happy with how my new brakes work.

Old Faithful

  • Familiarity: I've put it through the wringer

Can't complain about XT brakes. Over the years they have always been awesomely consistent. A good standby for any type of riding.

go to brakes

  • Familiarity: I've put it through the wringer

The XT have been my go to brakes for quite a while now. I've tried others and always seem to come back. Maintenance is minimal and power is great.

Now I have to update my other bike!

  • Familiarity: I've put it through the wringer

Have Shimano BR-M445 brakes on my 7 year old Niner that I just flushed, added new oil & new pads, they work well. Then I bought new 5010 from you guys with these brakes. Crap • these are so good now I have no choice but to update my Niner to these • night and day difference. These are by far the best brakes I've used. Plus, being able to easily service myself and mineral oil instead of DOT make these a no brainer.

best for the price

  • Familiarity: I've put it through the wringer

I have used Shimano for a long time and the Xt stuff is awesome! works great and not crazy expensive. Big fan of the saint breaks too if you're looking for more stopping power.

Shimano XT brakes work, over and over

  • Familiarity: I've put it through the wringer

If you want your bike to these. EASY to maintain too....
Nuff said...

Without a doubt the most reliable brakes

    These are my second pair. I replaced some SRAM brakes on my first bike and now I just replaced some SLX brakes on my new bike. My rider weight is 235 so I need a good brake that doesn't fade on the down hills. This brake has good modulation, power, and I love the one finger lever action. Pair these with the XT rotors and you have a match made in heaven. Did I mention they are also quiet? Well they are! For an all mountain/ Trail brake these will work just fine. They aren't as heavy duty as the Zee or Saints and also not as heavy. If you aren't a down hill rider on weight more than 235 than these will work just fine.

    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.
