Abstract

A disc brake for a utility vehicle has a brake caliper which fits around a brake disc, is in the form of a sliding caliper, is fastened to a stationary brake carrier and has a central opening over the brake disc. The disc brake has two brake pads which are arranged in the brake caliper, can be moved in opposite directions and each have a pad carrier plate and a friction lining fastened thereto, and of which an action-side brake pad can be pressed against the brake disc by a tensioning device via at least one brake piston. The disc brake also has at least one spreading device with which the brake caliper can be returned after a displacement caused by braking and after a release of the brake. The spreading device has resilient spring units which act on the mutually opposing brake pads. The spreading device is arranged in the central opening, and the spring units act directly or indirectly outside the friction linings in at least two attachment interfaces, spaced from each other and from the center, of the brake pads. The spring units are connected to a stationary attachment element in at least one connection interface by at least one connection element.
