Shimano Deore XT Disc Brake BR-M8220 (P04C-MF Metal Pad)

Overview

The Shimano Deore XT BR-M8220 is a hydraulic 4-piston disc brake caliper designed for mountain bikes with post-mount compatibility. Featuring P04C metal pads with cooling fins and low-viscosity mineral oil, this enduro-focused caliper delivers high stopping power and precise control across rough and steep trail conditions.

Key Features

• Hydraulic 4-Piston Design — Four pistons deliver high stopping power and improved modulation compared to 2-piston systems; ideal for enduro and trail riding where braking control is critical
• Post-Mount Compatibility — Post-mount standard ensures broad compatibility with most mountain bike frames and forks; straightforward installation and maintenance
• P04C Metal Pads with Cooling Fins — Sintered metal friction material delivers strong, consistent stopping power; integrated cooling fins improve heat dissipation during extended or aggressive braking
• SERVO WAVE ACTION — Optimized power curve manages pad-to-rotor friction throughout lever pull; delivers better balanced braking and improved modulation across varied braking inputs
• Low-Viscosity Mineral Oil Compatible — New formulation maintains consistent braking power across wider temperature range; improves performance in cold and hot conditions
• BL-M8200 Lever Compatibility — Engineered to pair with BL-M8200 lever for consistent brake system performance; delivers high stopping power and control in rough terrain
• Enduro-Focused Design — 4-piston configuration prioritizes stopping power and control over weight; built for aggressive trail riding and technical descents
• Flexible Pad Options — Compatible with multiple pad materials (D02S-MX, D03S-RX, N03A-RF, N04C-MF, P03A-RF, P04C-MF) allowing customization for riding style and conditions

Compatibility & Ideal Use Cases

Compatible exclusively with post-mount brake frames and forks and 6-bolt rotors. Requires low-viscosity SM-LVOIL mineral oil (sold separately); standard DOT or other mineral oils will damage seals and reduce performance. Designed primarily for mountain biking, not BMX use. Ideal for enduro and trail riders seeking high stopping power and precise control on rough, steep terrain. The 4-piston design and metal pads make this caliper well-suited for aggressive riding where consistent braking power is critical. Pair with BL-M8200 lever for customized enduro braking performance. The flexible pad compatibility allows riders to tune braking characteristics for specific conditions. Not suitable for BMX, road, or cross-country applications where weight savings are prioritized.
