ABSTRACT:
A wheel cylinder and torque plate construction is provided for a drum brake. The wheel cylinder comprises a molded plastic cylindrical member in a steel shell. The steel shell can be part of a torque plate which can be stamped in two parts which are substantially identical and then affixed together. The torque plate parts have semicylindrical shells which form the wheel cylinder shell when the parts are assembled. The plastic cylinder can be molded in the shell in a suitable die or mold in a plastic molding machine.
