Abstract:
1. A self-boosting vehicle brake comprising a rotatable brake body that can be braked, a friction brake lining, an actuating device with which the friction brake lining can be pressed against the rotatable brake body for actuating the vehicle brake, a self-boosting device which converts a frictional force, exerted when the vehicle brake is actuated by the rotatable brake body, on the friction brake lining that is pressed against the brake body, into a contact pressure that, in addition to a contact pressure exerted by the actuating device, presses the friction brake lining against the brake body and thereby boosts a braking force of the vehicle brake, a support means supporting the self-boosting device for movement in a direction of rotation of the brake body, and a disengageable fixation device operable for fixing the self-boosting device against moving jointly with the brake body, wherein the self-boosting device includes an abutment against which the friction brake lining is braced, the abutment being slidably supported by the support means so as to be displaceable in a circumferential direction of the brake body, and the disengageable fixation device being able to fix the abutment from movement in the circumferential direction; wherein the disengageable fixation device is actuatable between an engaged state and a disengaged state.
