Abstract
In a hydraulic drum brake and parking brake assembly, when a hydraulic actuator is operated to engage an opposed pair of brake shoes with a brake drum after a predetermined amount of wear had occurred on the friction pads of the brake shoes, a torsion spring adjusts a cam in the parking brake portion of the mechanism to compensate for the wear. The parking brake will thus operate properly despite the wear.
