Abstract: A friction lining or structure of a vehicle disk brake, including an absorption body with a mass MT, with a rear plate including hammer-head-shaped projections and friction material, which is fastened to the rear plate, for bearing against a friction ring, and wherein the projections engage in abutments of receiving recesses in a holder profile for the tangentially fixed holding and the axially displaceable guidance, and therefore introduction of a tangentially directed circumferential force (Fu, friction force) into the holder profile induces a tensile stress in at least one projection. An absorption system for suppressing undesirable vibrations is arranged on the friction lining.

Abstract: A guiding system for a brake piston of a motor-vehicle disk brake comprises a brake piston, a cylindrical brake-piston bore for accommodating the brake piston in a housing in such a way that the brake piston can be axially displaced, and a ring seal supported in the housing in an axially immovable manner, which ring seal is elastically clamped between a cylindrical brake-piston wall and a recess in the brake-piston bore. In order to improve the NVH behavior in the avoidance of disturbing noises of motor-vehicle disk brakes, a reversibly elastically preloaded guiding means is clamped between the brake-piston bore and the brake-piston wall, which guiding means is supported on the housing and couples the brake piston to the brake-piston bore in such a way that the brake piston is oriented in a specific manner.

Abstract: The invention relates to a brake actuation unit for a motor vehicle brake system, a vacuum brake booster and a motor pump unit which is provided for supplying a vacuum and comprises a pump connected to the vacuum brake booster and an electric motor driving the pump. According to the invention, an additional sound absorbing element is provided in the connection between the vacuum brake booster and the pump in order to lower the sound level in the vehicle interior.
