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 new system also frees up a bit of space on your dashboard with a narrower clamp. The BL-M000 also comes with a new lever with an integrated master cylinder and, of course, a menacing black ano finish. 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.
