ABSTRACT:
An air-actuated disc brake develops the required force magnification to operate disc brakes from an air pressure chamber using push-pull rods driving a pair of cam levers applying normal force to one shoe plate of the disc brake. Clamp action is carried through to an opposing brake shoe plate by a caliper. The entire air applied disc brake is mounted as a unit to the axle flange. An automatic adjuster compensates for brake lining wear. The cam levers are pivotally mounted to a movable cam carrier located between the caliper and one brake shoe plate.
