Beschreibung
Zusammenfassung:	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.
