Say hello to XTR Trail brakes, and say goodbye to compromise. The integration of Servo-Wave brake-boosting technology into an XTR-level brake generates gobs of lightweight stopping power (125 percent of the previous XTR benchmark, to be exact) that can be precisely rolled on and off with single-finger effort-leaving a better grip on the bar for charging through the gnar. The Shimano XTR BL-M988 disc brakes deliver a balance of light weight and power that resists performance-sapping heat better than ever before thanks to an industry-first full-ceramic piston and optional Ice Technology radiator brake pads. Each individual brake comes with brake lever, and caliper. Rotors are not included.
Hint for breaking-in: New disc brake pads require a certain break-in period in order to provide the full brake power. The following procedure has proved oneself: drag braking on a downhill until the brake power noticeably increases. Then let the brake rotor cool out. Afterwards do 20 full stops braking from a medium speed. Attention: the rotors get very hot, do not touch them!
