Abstract

A vehicle disk brake has a brake-application device providing a braking force and has a force element and a pressure-boosting lever arrangement. A readjustment device for compensatory readjustment of the wear-induced air clearance of the brake is provided that has a rotatably arranged drive element to be actuated by the brake-application device, a readjustment element arranged rotatably on the same axis, and a transmission device arranged in the movement path between drive element and readjustment element. To provide a readjustment device of a structurally simple design with a small number of parts, the transmission device is in the form of a helical wrap spring which is radially supported at the inner side along a first helix section relative to the drive element and is radially supported at the outer side along a second helix section relative to the readjustment element.
