description This invention relates to a leading/trailing type drum brake assembly in which the parking brake lever, adjuster strut and associated components are replaced with a single electronic subassembly that controls the parking brake, senses brake lining wear and adjusts the brake shoe-to-drum clearance to account for lining wear. The parking brake assembly includes a strut actuator subassembly that comprises a strut tube, an electric motor, a position encoder, a power screw and a connector fork. A parking brake assembly for an automotive drum brake is provided. The parking brake assembly replaces a conventional mechanical strut with an electronic strut actuator subassembly that provides for parking brake engagement and disengagement, sensing of brake lining wear and adjustment of brake shoe-to-drum clearance.
