Abstract: A clutch or brake system for a heavy duty vehicle is provided having an assembly which includes a shoe having an exposed surface on which is attached a carrier member. A friction liner is molded onto the carrier member. The carrier member is provided with a plurality of apertures, each having a peripheral flange embedded into a concealed surface of the liner. The attachment of the carrier member to the shoe exposed surface permits relative adjustment therebetween, when the assembly is in a braking or clutching mode, so as to compensate for any differential in coefficients of thermal expansion between the shoe and the carrier member on which the liner is molded.
