The two-part BR-M8220 brake caliper with four pistons is the strongest in the M8200 family and has been designed for maximum performance, consistency, and control. The new low-viscosity oil ensures that the bite point of the M8220 brakes remains consistent in all terrain and weather conditions, and the new brake pads eliminate rattling noises caused by vibrations. Increased performance and consistency provide the rider with pinpoint control on rough trails.
