Abstract
A drum brake assembly includes a backing plate for supporting a pair of brake shoes and a hydraulic actuator which cooperates with the pair of brake shoes to urge the latter into a braking position. A parking lever is pivotally mounted on one of the brake shoes and a strut connects the parking lever with the other brake shoe such that rotation of the parking lever when the parking brake is applied urges the pair of brake shoes into a braking position. In order to connect the strut to the other brake shoe while at the same time eliminating any rattle between the pair of brake shoes and the struts, a spring clip releasably connects with the other brake shoe and resiliently engages the strut to bias the latter toward the one brake shoe. The spring clip is substantially U-shaped with at least one opening for receiving the strut and for maintaining the strut in juxtaposition to the other brake shoe.
