The HRD/HRR Hydraulic Brake Master Piston Assembly Kit contains the parts necessary to restore the functionality and performance of select SRAM road and gravel bike style shifter/brake lever assemblies. If the brakes are losing fluid within the shifter/brake lever assembly this kit will restore the sealing within the master piston, resulting in less frequent bleeding procedures and restored power. This kit will include a replacement bleed screw and bleed screw o-ring.
