Abstract: A disc brake piston (50) includes a body (52) formed from a plastic material and a cover (70) formed from a metallic material. The body (52) of the piston (50) is molded from a synthetic resin material and is generally hollow and cylindrical in shape, defining an axis and including an opened end (56) and a closed end (54). The body (52) defines an inner cylindrical surface (58) and an outer cylindrical surface (60) which extend axially from the opened end (56) toward the closed end (54). The cover (70) is formed from steel and is integrally molded to the body of the piston (50).
