XTR BL-M9120 Disc Brake delivers unrivaled control and power for aggressive trail and enduro riding.
What Our Gearhead® Experts Are Saying:
"If pushing limits is your game, the XTR BL-M9120 is the answer. The four-piston power gives me total confidence over technical features, even when things get steep and loose. Setup is dialed and modulation is top-notch—this brake elevates any bike on the trail."
Built for the ride where control can’t be compromised, the XTR BL-M9120 Disc Brake backs every line with top-tier Shimano engineering. The four-piston caliper packs a forceful bite that’s responsive but never grabby, easily taming rocky chutes and big drops. Servo Wave and Freestroke adjust let you dial the feel to perfection, while the strong, lightweight lever adapts with I-Spec EV for a neat cockpit. Add in tool-free reach adjust and a refined lever shape, and the result is flawless braking performance for long, punishing rides—all with Shimano’s legendary reliability.

To the other poster,you CAN buy replacement pistons. The company that has a smile logo has a kit that includes the 15.1mm piston. Works fine.

XTR BL-M9120 ceramic piston fail
I know how to bleed brakes for years with a proper bleed kit, these ceramic brake pistons crumble from inside/rear even with proper brake bleed block. No option to purchase replacement ceramic piston other then buy whole new XTR caliper $$$$
