ABSTRACT:
A master brake cylinder comprises a reservoir and a cylinder for generating fluid pressure. Provided in the cylinder is a sliding piston, and mounted to front and rear ends of piston are piston cups for sealing a gap between the piston and the cylinder. The piston cups comprise a substrate made of rubber and a coating layer made of diamond-like carbon and provided on an outer peripheral surface (sliding surface) of the substrate. A surface of the coating layer constitutes a sliding surface, and so a frictional resistance thereof relative to an inner peripheral surface of the cylinder, on which the coating layer slides, is made relatively low. The coating layer can easily follow deformation of the substrate and securely adheres to the substrate.
