Abstract
A sealing member in a disk brake, in which a piston fitted in a cylinder is to urge a friction pad onto a rotating disk, includes a sealing ring disposed in a circumferential groove provided in the cylinder or on the piston. A spring member is disposed between the forward surface of the sealing ring and the forward wall of the groove for constantly biasing the sealing ring backwardly in order to return the piston substantially to the same position when the brake is released, regardless of the magnitude of the braking pressure applied, while preserving the function of automatic compensation for the wearing of the friction pad.
