Disc brake and brake lining assembly having a restoring device

The invention relates to a disc brake (10), in particular for a motor vehicle, comprising a support (12), a brake pad assembly (14), the guided one in the carrier (12) friction lining with a friction lining backplate (16) and a restoring device (18) comprises , The pad back plate has a first recess (20) and the friction lining is provided with a brake disc for achieving a braking effect can be brought into interaction. The restoring device comprises at least one return spring which is supported by the carrier (22), and it is adapted to exert a restoring force on the pad back plate, to return the friction lining after a deflection to a starting position. The brake pad assembly comprises at least one coupling part (24) which extends substantially perpendicular to a surface of the pad backing plate through the first recess and is engaged with this under radial prestress, so that between the coupling member and the inner circumferential surface of the first recess is a through bias of the coupling part acts against the inner circumferential surface caused friction force. The coupling member is adapted to couple the return means with the pad back plate and to slide along its longitudinal direction in the first recess, when the resistance of the restoring device against the deflecting movement exceeds the frictional force, so that the pad back plate is displaceable relative to the coupling part for wear compensation.
