When parking braking occurs, the pads (8) are applied onto the disc brake (4) by means of a piston (2) which is moved by rotating a screw (1) in a nut (3) (or vice versa) which becomes blocked by means of friction during loading and triggers the spacing of the two plates (6, 7) of a mechanism (5) consisting of balls and ramps placing the pads (8) in a state of bearing stress. The overall theoretical performance of the system thus described is 98 %.
