Abstract

A disc brake has a brake caliper, which reaches over a brake disc, is designed as a sliding caliper, is fastened to a stationary brake bracket and has a central opening over the brake disc. Two brake pads, which are arranged in the brake caliper and can be moved in opposite directions each have a backing plate and a friction lining fastened thereto. An action-side brake pad can be pressed against the brake disc by an application device by way of at least one brake piston. At least one restoring device is provided, by which the brake caliper can be returned after displacement and release of the brake caused by braking, wherein the restoring device has a spreading device, which acts on the brake pads lying opposite each other and acts in the same way against each particular application direction and has resilient spreading elements that act on the respective backing plates. The spreading device is arranged in the central opening, wherein the spreading elements act directly or indirectly outside of the friction linings on one side in the center region or at least two contact regions of the brake pads arranged at a distance from each other with respect to the center, wherein the contac…
