ABSTRACT:
The invention relates to a brake actuator with automatic adjustment of the type including a screw and nut actuating mechanism (32) the lengthening of which is controlled by a combined system with a screw and nut of reversible pitch and a unidirectional clutch (42) which is responsive to the relative axial movement between a control piston (14) and a fixed body (10) housing the control piston (14). The brake actuator includes a device for controlling (62) the rotation of the nut (34) of the actuating mechanism (32) so as to allow rotation of the nut (34) beyond a predetermined value of torque for rotating the latter.
