Abstract

A disc brake for a commercial vehicle includes a brake caliper which extends over a brake disc, a brake application device which is arranged in the brake caliper for pressing brake pads against the brake disc, and at least one adjustment spindle which is rotatably mounted in a bridge via a threaded coupling. A wear adjusting device is positioned in the brake caliper by which a wear-induced change of the clearance between the brake pad and the brake disc can be substantially compensated for via an axial movement of the adjusting spindle. The disc brake is designed such that the adjusting spindle has at least one axial groove on an outer side, the length of the groove being limited in the direction of the brake application device. A stop, which is axially fixed relative to the bridge, engages into the axial groove in a relatively displaceable manner.
