A backing plate (10, 10a) for supporting a friction lining in a disc brake assembly. The backing plate (10, 10a) is made of a thin sheet of corrosion resistant metal that has a recessed portion extending from a substantially rectangular base. The base has fixing brackets located on the top thereof with tabs which engage pins on the disc brake assembly. The recessed portion which is offset from the center of the rectangular base has a substantially circular shape that corresponds to an actuation piston of the disc brake assembly. The friction lining which engages the rectangular base has an additional thermal barrier located in the recessed portion. When the friction lining engages a rotor in the disc brake assembly, thermal energy is created. The thermal energy is carried through the friction lining to the backing plate; however, the thermal barrier substantially eliminates the direct flow of thermal energy to the actuation piston. In addition, the offset portion also reduces the production of noise associated with a brake application.
