摘要

The disk brake has a pressure plate (11) that is designed as a perforated disk. A hole (45) of the pressure plate is centrally arranged on a plunger (10). A pin (30) that faces a brake pad is locked axially with respect to the brake pad. A locking ring (40) locks the pressure plate axially in a complete or partial state. An end that faces a locking ring abutment surface (44) of the pressure plate is arranged in an annular groove (41) of the pin. A pressure surface (12) of the pressure plate is formed in a recess as compared to the locking ring abutment surface.
