Abstract

A resetting device by which a brake caliper can be reset after a braking-induced displacement and release of a brake. The resetting device has a spreading device which has resilient spreading elements. The spreading device is arranged in a central opening of the brake caliper. The spreading elements engage, outside the friction pads, directly or indirectly on one side at at least two abutment regions arranged spaced apart from one another relative to the center, of the brake pads, where the abutment regions have one abutment surface and one bearing surface on which the spreading elements are movably arranged. The spreading device has spring arms, of which in each case two lie against an associated pad carrier plate, where the spring arms are connected to one another in the central region of the opening. The spring arms are connected to a retaining bow which is attached to a brake carrier.
