ABSTRACT:
A disc brake unit for machinery, hoists and the like having a pair of brake shoes normally spring biased to a brake engaged condition. A hydraulically operated first piston may be hydraulically actuated to relieve the spring bias to release the spring pressure acting on the disc and thus release the brake. A second piston may then be actuated for moving the brake shoes against the disc and applying a modulated force to the disc while the fist piston is in position to oppose the spring bias, to thereby apply slip braking torque to the output shaft.
