Abstract
A first threaded member is supported for rotation about a screw axis (C; C'; C') parallel to the axis (A) of a brake disc in a casing which is disposed axially next to the brake disc when in built-in position. A second threaded member is fixed against rotation and connected to the first threaded member by a readjustment thread pair so that the two threaded members together form a longitudinally adjustable tappet for exerting an actuating force on a brake pad. A rotary member is rotatable about an axis of rotation (B) of its own which extends at least approximately parallel to the brake disc, for axially displacing the tappet by means of an actuator member. A gear connection is provided between the rotary member and the first threaded member, comprising an angle drive and a coupling arrangement to transmit a limited torque for readjustment of the brake pad mentioned.
