The present invention relates to a friction brake, in particular a disc brake, for a motor vehicle with a friction element, e.g. a brake disc, coupled to the rotation of a vehicle wheel, forming a friction pairing of the friction brake with at least one associated brake lining, and with at least one clamping device for pressing at least one brake lining to the friction element. At least one controllable friction clutch is provided for using the rotational energy of the friction element in order to obtain the clamping force of the friction brake, the friction clutch being coupled on its input end to the rotation of the friction element and on its output end to the clamping device. Functional advantages are achieved because a friction pairing of the friction clutch is provided independently of the friction pairing of the friction brake. This eliminates undesired mutual influences. Altogether, such a friction brake obviates the need for an additional energy source for generating a brake clamping force.
