ABSTRACT:
Inner and outer brake shoes are swivel-mounted on the arms of a yoke. When the yoke is rotated, the shoes move concurrently toward and away from inner and outer braking surfaces of a brake drum. The swivel mounting facilitates optimum seating engagement with the braking surfaces and in cases where the drum is warped, serves to maximize braking area and minimize wear. Stops positioned near opposite ends of the shoes limit their circumferential movement. An electric puck or a hydraulic actuator is used to rotate the yoke.
