We claim: 1. A disk brake with self-boosting comprising: a friction brake lining, an actuation unit with which the friction brake lining can be pressed against a brake disk, and a self-boosting device which, when the disk brake is actuated, converts a frictional force, exerted by the rotating brake

We claim: 1. A disk brake with self-boosting comprising: a friction brake lining, an actuation unit with which the friction brake lining can be pressed against a brake disk, and a self-boosting device which, when the disk brake is actuated, converts a frictional force, exerted by the rotating brake disk against the friction brake lining pressed against it, into a contact-pressure force which, in addition to the actuation unit, presses the friction brake lining against the brake disk, and the self-boosting device having a wedge plate on a back side of the friction brake lining, remote from the brake disk, that is braced on a counterpart wedge plate braced axially on a support plate, said counterpart wedge plate being movable with respect to said support plate, wherein the disk brake (10) comprises a wear readjusting means (54) to compensate for wear of the friction brake lining (14, 16); the wear readjusting means (54) having an actuator (22; 60; 64); the wear readjusting means (54) being operable to adjust a spacing between the support plate and the brake disk (18), wherein the friction brake lining (14, 16) is located in a caliper and wherein the wear readjusting means (54) comprises a thread (42) positioned on a peripheral portion of the support plate which meshes with a thread (44) located on the caliper. 2. The disk brake in accordance with claim 1, wherein the actuator of the wear readjusting means (54) comprises an electric motor (60) for rotating the thread (42) of the support plate. 3. The disk brake in accordance with claim 1, wherein the wear readjusting means (54) comprises a stepping drive mechanism (62), with which the thread (42) of the support plate is rotatable in stepped fashion.
