Patent ID: 7364021

Claim:
In a wheel brake for a motor vehicle, including a friction brake lining ( 20 ) and a plurality of actuating devices with which the friction brake lining can be pressed against a brake body ( 14 ) for braking, the improvement wherein the actuating devices comprise both an electromechanical actuating device ( 16 ) and a pressure fluid actuating device ( 17 ) for pressing the friction brake lining ( 20 ) against the brake body ( 14 ); wherein the actuating devices ( 16 , 17 ) are redundant and the contact-pressure forces exerted by the two actuating devices ( 16 , 17 ) on the friction brake lining ( 20 ) are added together; and a support member ( 22 ) on the side of the friction brake lining opposite the brake body, the support member having two wedge inclines ( 24 ) and a flattened middle portion on a side opposite the friction brake lining, the pressure fluid actuating device having a tappet ( 48 ) resting on the flattened middle portion.
