Abstract
In a disk brake actuated preferably hydraulically, a piston (5) is guided within a housing located in a caliper. When pressure is applied, the piston acts in such a manner against a brake shoe (15) bearing a brake lining (17) that the brake shoe (15) is pressed with its brake lining against the brake disk to be braked. The side of the piston facing the brake shoe has a pressure plate (13) which transmits the pressure forces and which moves transversely within its recess in the piston (5). The pressure plate (13) is mounted on the end of a tappet (25) extending axially inside the piston (5) and bracing itself at the end opposite the pressure plate by a disk (27) at the bottom (29) of the bore (31) accommodating the tappet, and is surrounded by a prestressed compression spring (37). Lateral movements of the pressure plate (13) cause tipping of the tappet (25) and, as a consequence thereof, a reset force exerted by the compression spring (37 ) on the tappet (25) and, thus, on the pressure plate (13). This reset force can be precisely defined by use of a threaded ring (39) whose position can be changed and which braces one end of the compression spring (37).
