ABSTRACT:
The invention concerns a brake actuator with automatic adjustment, of the type incorporating a screw and nut system with reversible pitch (46, 48) situated between a working piston (40) and a control component (34), the screw and nut system transmitting a force between the control component (34) and the working piston (40) when relative rotation between the screw and the nut is locked by a locking device (50-54). The brake actuator incorporates an automatic relative axial positioning device (56) between the control component (34) and the working piston (40) providing a predetermined approach travel between the working piston (40) and a friction component (42) capable of being pushed by the brake actuator.
