Disc brake and set of brake pads

A disc brake for a vehicle, comprising:

• a brake disc having a brake disc rotational axis;
• a brake carrier configured to straddle the brake disc;
• an application-side brake pad and a back-side brake pad with respective back plates configured to be supported directly on the brake carrier in respective brake carrier pad slots;
• a brake caliper configured to straddle the brake disc while being supported on the brake carrier in a manner that enables sliding of the brake caliper relative to the brake carrier along a direction parallel to the brake disc rotational axis;
• at least one pad-retaining spring coupled to the application side brake pad,
• wherein
• the brake carrier and at least the application side brake pad have form-fitting complementary contours configured such that the form-fitting complementary contours directly abut one another when at least the application side brake pad is in an installed position in the brake carrier to constrain the application-side brake pad against radial movement away from the brake disc rotational axis, and
• the at least one pad-retaining spring is configured to be supported at opposite ends directly on brake carrier horns adjacent to the application-side brake carrier pad slot and to exert a tensile force in a radially outward direction on the application-side brake pad,
• the form-fitting complementary contours include opposing brake carrier projections into the application-side brake carrier pad slot and complementary recesses in opposite lateral sides of the application-side brake pad,
• undercut surfaces of the contours of the brake carrier horns are configured to engage in a play-free manner undercut surfaces of projections of the pad back plate located radially inward of the brake pad recesses,
• the at least one pad-retaining spring includes a spring element at each of opposite lateral sides of the upper side of the application-side brake pad back plate,
• the spring elements at the opposite lateral sides are located on the application-side brake pad back plate and extend over their respective adjacent brake horns,
• the spring elements are located on the application-side brake pad back plate on respective spring holders of the back plate above the upper side of the back plate, and
• the spring elements are held on their respective spring holders by respective retaining elements.
