Disc brake, particularly for a commercial vehicle, having a) a brake calliper which engages over a brake disc and is configured as a sliding calliper, b) two brake linings (4, 5) which are arranged in the brake calliper, can be moved in opposite directions and make contact with the brake disc in the functional position, c) at least one fastening element which has a guide spar for fastening the brake calliper to a stationary brake carrier, d) a brake application device, with which the associated action-side brake lining can be pressed against the brake disc via at least one control spindle, e) an adjusting device which is connected in a rotationally locked manner on the control spindle and with which a wear-induced change in an air play between the brake linings (4, 5) and the brake disc can be substantially compensated, f) a restoring device which is arranged on the action side and has a restoring element which can be deformed elastically during the braking-induced displacement of the brake calliper, with which restoring device the brake calliper can be brought automatically into an initial position counter to the displacement direction during the brake application, characterised in that g) the restoring device has a supporting part which remains in its position with respect to the brake carrier during the braking-induced displacement of the brake calliper and is operatively connected to the resilient restoring element with deformation of the latter, or forms the restoring element, h) wherein the maximum possible displacement force of the restoring element is less than the minimum possible actuating force of the adjusting device or i) the minimum possible displacement force of the restoring element is more than the maximum possible actuating force of the adjusting device. a) a brake calliper which engages over a brake disc and is configured as a sliding calliper, b) two brake linings (4, 5) which are arranged in the brake calliper, can be moved in opposite directions and make contact with the brake disc in the functional position, c) at least one fastening element which has a guide spar for fastening the brake calliper to a stationary brake carrier, d) a brake application device, with which the associated action-side brake lining can be pressed against the brake disc via at least one control spindle, e) an adjusting device which is connected in a rotationally locked manner on the control spindle and with which a wear-induced change in an air play between the brake linings (4, 5) and the brake disc can be substantially compensated, f) a restoring device which is arranged on the action side and has a restoring element which can be deformed elastically during the braking-induced displacement of the brake calliper, with which restoring device the brake calliper can be brought automatically into an initial position counter to the displacement direction during the brake application, characterised in that g) the restoring device has a supporting part which remains in its position with respect to the brake carrier during the braking-induced displacement of the brake calliper and is operatively connected to the resilient restoring element with deformation of the latter, or forms the restoring element, h) wherein the maximum possible displacement force of the restoring element is less than the minimum possible actuating force of the adjusting device or i) the minimum possible displacement force of the restoring element is more than the maximum possible actuating force of the adjusting device.
