Abstract
The invention concerns a brake actuator with automatic adjustment incorporating a screw and nut actuator mechanism (32, 34) whose elongation is controlled by a screw and nut device with reversible pitch (44) and a unidirectional clutch (56) sensitive to the relative movement between the fixed body (20) and a control piston (24). The brake actuator incorporates an automatic device (68) momentarily disengaging the actuator mechanism (32, 34) when the rotational torque of the nut (32) becomes too great. The brake actuator also incorporates a manual device for resetting the automatic adjustment to zero.
