Disk brake for a utility vehicle and brake pad set

The invention relates to a disk brake (100), comprising a brake caliper (1), which reaches over a brake disk (2), is designed as a sliding caliper, is fastened to a stationary brake bracket (6) and has a central opening (41) over the brake disk (2), further comprising two brake pads (3), which are arranged in the brake caliper (1) and can be moved in opposite directions and each have a backing plate (4) and a friction lining (5) fastened thereto and of which an action-side brake pad can be pressed against the brake disk (2) by an application device by means of at least one brake piston, and at least one restoring device, by means of which the brake caliper (1) can be returned after displacement and release of the brake caused by braking, wherein the restoring device has a spreading device (8), which acts on the brake pads (3) 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 (4). The spreading device (8) is arranged in the central opening (41), wherein the spreading elements act directly or indirectly outside of the friction linings (5) on one side in the center region or at at least two contact regions of the brake pads (3) arranged at a distance from each other with respect to the center, wherein the contact regions each have a contact surface and a bearing surface, on which the spreading elements are movably arranged. The invention further relates to a corresponding brake pad set.
