41764-58 Rear Brake Master Cylinder Cap & Dust Seals

This Cycle Pro LLC rear brake master cylinder cap and dust seal kit provides the necessary components to refresh the sealing system of a Harley-Davidson rear braking assembly. Replacing OEM part 41764-58, these gaskets and seals are engineered to withstand the harsh environment of the braking system, preventing leaks and keeping contaminants out of the hydraulic fluid. The materials are compatible with DOT 3, DOT 4, and DOT 5 brake fluids, though it is critical to maintain the specific fluid type already in your system to avoid chemical incompatibility. Cycle Pro LLC focuses on precise manufacturing to ensure these seals provide a reliable barrier against moisture and dust, maintaining consistent pedal feel and braking performance.
