The Shimano XTR BR-M9220 is Shimano's flagship 4-piston hydraulic disc brake calliper, engineered for trail and enduro mountain biking where consistent, powerful braking is non-negotiable. Machined from a single piece for exceptional stiffness, it delivers DH-capable power with the refined modulation XTR riders expect — supplied here with the P03A resin fin pad included.

Highlights

• Dual-diameter 4-piston design: Opposing pistons of two different sizes deliver a progressive, controlled power curve — strong initial bite with precise modulation at the lever.
• Low viscosity mineral oil: Shimano's updated low viscosity oil maintains a consistent bite point across all temperatures and trail conditions, eliminating the fade that plagues brakes in heat or cold.
• Single-piece machined body: The calliper is CNC-machined from a single aluminium billet for maximum rigidity and minimal weight, reducing flex under hard braking loads.
• Revised pad retention system: An updated oval pad mount and revised seals eliminate the pad rattle common on older designs — quieter on the trail, more confidence-inspiring under braking.
• ICE Technologies pad compatible: Supports both resin and metal pad options (finned or non-finned) so you can tune brake feel and heat management to suit your riding style and conditions.
• Banjo hose connection: Clean banjo-style hose fitting (SM-BH90-SBM hose) keeps routing tidy and simplifies bleeding.

XTR M9200 Series

The BR-M9220 sits at the top of Shimano's M9200 XTR groupset — the same platform trusted by elite enduro and trail racers worldwide. It pairs directly with the BL-M9220 enduro brake lever for a matched system with optimised lever feel and power delivery. The M9220 calliper is the 4-piston variant, purpose-built for riders who demand maximum stopping power from their trail or enduro build.

Pad & Rotor Setup

This calliper is supplied with the P03A resin fin pad — Shimano's resin compound with a finned backing plate for improved heat dissipation. Compatible rotors include the RT-CL900 and RT-MT905 in sizes from 160mm through to 220mm. For demanding descents, pairing with Shimano's IceTech rotors is recommended to keep temperatures in check.
