An arrangement for disc brakes for motor vehicles, which comprise a power actuator (7) attached to the outside of the brake yoke (1) and which have a pressure bar (10) which extends through a through-going opening in the brake yoke and interacts with an end (47) of a lever (13) which is part of a power transmission (8) between the power device and the brake lining units, where the end (47) is arranged inside the opening. A sealing means (14) has a supporting, ring-shaped, surface-covering portion made of a non-deformable, resilient material with a through-going opening (27). In an operational state of the power actuator (7) an inlet for the pressure bar (10) is formed. A peripheral outer ring-shaped sealing portion (16) connects to the edge section of the inlet opening (49). A peripheral inner sealing portion (17) extends around the opening in the supporting portion and connects in a servicing condition with the power actuator (7) removed against a contacting surface (48) of the end of the lever, which thereby seals the opening in the sealing means. |
