AN IMPROVED DISC BRAKE Abstract of the Disclosure An improved disc brake is of the type which includes a disc mounted for rotation about an axle. An axle housing is mounted on the axle in alignment with a friction surface of the disc. An axially movable braking piston has an interior end at least partially mounted within the housing and an external end outwardly of the housing adjacent the friction surface of the disc. The braking piston has a plurality of axially extending splines about an exterior surface of the interior end to mate with corresponding splines on an interior surface of the housing to limit rotation of the braking piston relative to the housing. The brake is actuated by the piston being axially moved toward and away from the friction surface of the disc. Lubricant can be supplied and periodically resupplied to an interior of the housing. The improvement includes providing the housing with a cylindrical recess at the end thereof adjacent the disc for receipt of a sealing ring made of resiliently compressable material. The sealing ring has an outer peripheral edge to make contact with the cylindrical wall of the cylindrical cavity and an interior edge including a plurality of teeth which are compressed to he received in and make sealing contact with the plurality of axially extending splines of the braking piston.
