Abstract

The invention relates to a wheel brake for a motor vehicle including an electromechanical actuating device and a hydraulic actuating device, which are redundant. In this way, the likelihood of failure of the wheel brake is reduced. A self-boosting device increases a braking force of the wheel brake, so that an (underpressure) brake booster can be dispensed with. Wheel slip control is possible in a simple way by hydraulic actuation of the wheel brake and superposition of a braking force regulation on the electromechanical actuating device. The wheel brake includes a support member on the side of a friction brake lining opposite a brake body. The support member has two wedge inclines and a flattened middle portion on a side opposite the friction brake lining. The pressure fluid actuating device has a tappet resting on the flattened middle portion.
