A brake pad retaining device is provided for holding a brake pad within a brake caliper of an air disc brake system. The device may be formed as a spring which provides at least four retention forces at longitudinal ends of the brake pad in order to suppress brake pad kick motion and vibration, while applying a biasing force that pre-loads a caliper to its mounting pins. The device may include a mounting section that is coupled to a brake carrier, a first projection and a second projection. The first projection extends from one region of the mounting section to a region near a longitudinal end of the brake pad to thereby exert a radially inward force against the brake pad. The second projection extends from another region of the mounting section to an inner surface of the brake caliper to thereby exert a biasing force against the brake caliper.
