ABSTRACT:
An actuator for a disc brake caliper comprises a spring operable piston for applying pressure to the disc brake caliper when rendered effective through a self adjusting lead screw, one end of which is friction coupled to the piston to prevent rotation of the lead screw when the brakes are applied. A manual release screw is threaded through the piston to bear against the head of the lead screw through an anti-friction bearing when manual release is desired to at least partially release pressure of the piston on the head of the lead screw through the friction coupling to permit slippage in the friction coupling connection between the piston and the head of the lead screw and cause the piston to rotate the lead screw in a direction to permit release of the brakes.
