ABSTRACT:
A self-energizing disc brake is operated by an actuator which moves spreading pressure plates angularly in opposite directions to apply rotatable friction discs to radial surfaces in a stationary housing, and the actuator comprises a wedge for separating lugs on the plates, a spring for urging the wedge in a direction to separate the lugs, and a piston working in a cylinder bore for urging the wedge in the opposite direction when the cylinder is pressurized.
