Abstract
A disc brake includes a brake caliper that engages over a brake disc, the caliper having a central opening over the brake disc. The disc brake has two brake pads which are located in the brake caliper, can be moved in opposite directions and each of which has a pad backing plate with a friction lining secured thereon. An action-side or application-side brake pad of the two brake pads can be pressed against the brake disc by a brake application device with the aid of at least one brake plunger. The brake also has at least one restoring device, by which the brake caliper can be returned. The restoring device has a spreading device which engages on the brake pads lying opposite one another and which acts with an identical force in opposition to the respective application direction. The spreading device has spring-loaded spreading elements, each engaging on its respective pad backing plate. The spreading device is located in the central opening and the spreading elements engage directly or indirectly, outside the friction linings, on at least two contact regions of the brake pads. These regions face each other at a distance from the center. The spreading device has spring-loaded arms which are interconnected in the central region of the opening and connected to a retaining bracket which is attached to the brake support plate.
