Abstract
A self-boosting electromechanical friction brake for a motor vehicle in which, with an electromechanical actuator, a friction brake lining can be pressed against a brake disk, and the friction brake lining is braced in the brake caliper via a wedge mechanism, which effects a self boosting. A friction brake lining which is pressed by the actuator has with a lower coefficient of friction, and in particular with less relative fluctuation in the coefficient of friction, than another friction brake lining positioned fixedly in the brake caliper. An operation-dictated fluctuation in the coefficient of friction and thus a change in the self boosting is reduced, and as a result the disk brake, with a low coefficient of friction, can be actuated with less actuation force and less actuation energy.
