Genuine Shimano diaphragm unit (part number Y2RJ98060) for the XTR BL-M9220 hydraulic disc brake lever. The diaphragm seals the reservoir and compensates for fluid volume as the brake heats and cools, helping maintain consistent lever feel. Replace during a brake bleed or service if the diaphragm is damaged, deformed or leaking.
