Replacing a damaged caliper shouldn't require buying an entire brake set. The Shimano XT BR-M8200 2-Piston Disc Brake Caliper gives you just the caliper body, ready to pair with your existing BL-M8200 lever or to serve as a spare when trail mishaps bend or crack your current unit. This is also the caliper to grab if you're building up a frame from scratch and sourcing components individually, or if you want to swap from the 4-piston BR-M8220 to save weight on a cross-country build.

The 2-piston design prioritizes weight savings over outright stopping force. Where the 4-piston BR-M8220 targets enduro and gravity riders who need maximum power, the BR-M8200 suits XC racing and trail riding where every gram matters and braking demands stay more moderate. Heat-resistant resin pistons push the pads without transferring excessive heat back into the hydraulic fluid, which helps maintain consistent lever feel through long descents. The aluminum caliper body keeps weight down while providing enough material to absorb impacts from rock strikes.

Shimano's M8200-series brakes use a lower viscosity mineral oil than previous generations. The thinner fluid flows more easily at cold temperatures, which means your bite point stays consistent whether you're riding in summer heat or starting a cold morning shuttle run. The caliper requires Shimano's SM-LVOIL specifically, so don't top it off with standard Shimano mineral oil if you need to bleed the system. One Way Bleeding simplifies maintenance by routing fluid in a single direction, reducing the chance of trapped air bubbles that cause spongy lever feel.... Read More
