ABSTRACT:
A drum brake assembly is described to comprise a dual drum brake housing mounted to a vehicle wheel or shaft to be rotated therewith. The dual drum brake housing has two axially extending, concentric, radially spaced drum surfaces defining an annular channel between them. A torque member is fixed against rotation with the vehicle wheel and an expandable friction lining assembly is mounted to the torque member. The friction lining assembly is positioned within the annular channel and carries radially outward and radially inward facing friction linings. Upon expansion of the friction lining assembly each of the friction linings is moved into contact with the corresponding drum surface, thereby transferring braking force to the wheel.
