Abstract

A disc brake for a commercial vehicle is provided. The disc brake includes a brake caliper, preferably in the form of a sliding caliper, straddling a brake disc, being arranged on a fixed backing plate, and having an application device for applying the brake. The disk brake also includes two brake pads, each having a pad carrier and an affixed friction pad, and each being inserted into a pad shaft of the backing plate. The brake caliper has a central caliper opening over the disc brake. A hold-down bar is provided, designed in such a way that, of the two brake pads, it radially secures only the reaction-side brake pad in its lining shaft in the backing plate. The hold-down bar is held on the brake caliper by its end facing away from the brake pad. Additionally, the application-side brake pad is radially interlockingly secured in its pad shaft in the backing plate. The application-side brake pad has a brake pad spring, which is held on the application-side brake pad and includes ends which rest resiliently on horns of the backing plate.
