A disk brake having a brake disk, brake anchor plate, and brake linings, is configured such that the brake linings can be installed into the brake only in the correct orientation with regard to the brake disk. In the process, the position of the center of gravity of the brake linings (1) remains substantially on the center line (6). In one exemplary embodiment, recesses (3, 3a) in the brake lining (1) are slightly asymmetrical with regard to the center line (6). A variant of the disk brake provides a recess in the brake caliper, said recess extending obliquely with regard to the center plane of the brake.
