Shimano BR-M9220 XTR 4 Pot Disc Brake Caliper

Shimano BR-M9220 XTR 4 Pot Disc Brake Caliper delivers consistent, high-power braking with a lightweight design built for control and precision. Its dual-diameter four-piston system balances strong braking force with fine modulation, while the forged one-piece body enhances rigidity without adding bulk.

Key Features and Benefits:

• Dual-diameter four-piston design: Two different piston sizes apply pressure in a balanced sequence. This improves braking control while reducing pad wear. The result is strong, consistent stopping power with smoother modulation on technical trails.
• Forged one-piece caliper construction: Built from a single block of aluminium, the caliper is both strong and lightweight. This increases rigidity under load while trimming weight. The outcome is more efficient braking with reduced flex.
• Opposed-piston setup: Pistons press inward from both sides, which reduces pad drag and the leading effect during braking. This setup provides more controlled deceleration and smoother brake feel across changing terrain.
• Anti-rattle pad structure with revised backplate: Pads feature a wider base and oval hole to secure the pad pin firmly. This design reduces noise and improves pad stability, leading to a quieter, more secure ride.
• Compatibility with Ice Tech rotors and pads: The caliper pairs with Ice Tech rotors and finned pads to reduce heat build-up. This improves brake consistency on long descents and helps maintain lever feel under hard use.
• One-way bleeding and low-viscosity mineral oil: The system uses simple one-way oil routing with Shimano’s specific brake fluid. This keeps braking consistent across temperature changes, ensuring reliable lever response in all conditions.

Precision braking is the key advantage for riders choosing the BR-M9220. With enhanced rigidity, thermal control, and consistent pad contact, this caliper helps maintain braking force when it matters most. It’s ideal for riders who need dependable performance under load and during repeated heavy use.

Pair this caliper with your preferred rotor size and pad type to suit your riding style. Its advanced braking control, low weight, and noise reduction features make it a solid upgrade for serious trail and enduro riders.
