ABSTRACT:
A drum brake assembly includes a torque member which supports a hydraulic actuator. The hydraulic actuator is engageable with a pair of brake shoes and is operable to move the pair of brake shoes into a braking position. The torque member comprises a central portion which attaches to an axle assembly and a plurality of arms extending radially outward from the central portion. In the preferred embodiment the plurality of arms cooperate with the central portion to substantially form a Y-shaped member. One of the arms substantially forms the hydraulic actuator to integrally form the latter with the one arm. The other arms are provided with slots to direct the movement of the pair of brake shoes and a resilient spring within the slots opposes axial movement of the pair of brake shoes.
