Molded piston having metallic cover for disc brake assembly

摘要

A disc brake piston includes a body formed from a plastic material and a cover formed from a metallic material. The body of the piston is molded from a synthetic resin material and is generally hollow and cylindrical in shape, defining an axis and including an opened end and a closed end. The body defines an inner cylindrical surface and an outer cylindrical surface which extend axially from the opened end toward the closed end. The cover is formed from steel and is integrally molded to the body of the piston. The cover extends about the opened end of the body and extends axially inwardly toward the closed end along portions of both the inner and outer surfaces of the body.
