The Shimano XTR BR-M9220 Brake Upgrade Kit delivers elite-level braking for riders who demand the absolute best on aggressive trails and enduro terrain. Featuring the powerful four-piston BR-M9220 calipers paired with ergonomically advanced BL-M9220 levers, this kit offers downhill-caliber stopping power with precise modulation and a consistent, confidence-inspiring bite. Redesigned lever ergonomics align with the natural arc of your finger for improved feel and response, while a 5° upswept blade and tool-free reach adjust keep your hands dialed and ready to ride. Inside, Shimano’s latest low-viscosity mineral oil and upgraded internal seals ensure fade-free braking and a reliable bite point in any weather. The rattle-free BR-M9220 calipers offer smooth performance with the option of either P03A-RF resin or P04C-MF metal pads (both included) so you can tune your brakes for feel or heat resistance.
