ABSTRACT:
A drum brake assembly includes a backing plate which supports a pair of brake shoes and a hydraulic actuator cooperates with the pair of brake shoes to move the latter to a braking position. An anchor pin extends from the backing plate to oppose torque developed by the pair of brake shoes during braking. In order to align the pair of brake shoes with the hydraulic actuator, a single clip is carried by the anchor pin and the clip opposes axial movement between the backing plate and the pair of brake shoes opposes separation between the backing plate and the hydraulic actuator. In an alternative embodiment the single clip forms a hook at one end to releasably engage the backing plate.
