XT Deore 4 Pistion hydraulic brake caliper

The 4-piston, 2-piece BR-M8220 caliper is the strongest in the M8200 family, made to increase power, consistency, and control. New, low viscosity oil keeps the M8220 brakes' bite point consistent in all trail and weather conditions, and new brake pads eliminate rattling noise caused by vibration. Increased power and consistency give riders pin-point control on rough trails.
