Abstract
A mechanically actuated parking brake having a pair of brake shoes movably mounted and arranged in end-to-end relationship on a fixed backing plate. A pair of levers is pivotally mounted on the backing plate. The levers are interposed between a pair of opposed brake shoe ends and a hydraulic actuator for moving the brake shoe into engagement with the brake drum upon actuation of the vehicle service brake. The branch legs of a Y-shaped cable extend between the swinging ends of the levers with the main cable leg extending about a pulley and connected to a windup reel. The windup reel is rotatably mounted on one end of a brake actuating handle, with the other end of the handle being connected to a parking brake actuating pedal or lever. Application of the vehicle parking brake rotates the windup reel upon rotation of the handle which tensions the cable and draws the lever ends inwardly and expands the brake shoes outwardly into engagement with the brake drum.
