Rim brake tenders device for a hydraulic bicycle brake and hydraulic bicycle rim brake

摘要

The invention relates to a rim brake actuator device (1) for a hydraulic bicycle rim brake with a brake cylinder (10), in which a piston (20, 90) is displaceably arranged in the axial direction of the cylinder, a pressure chamber (5) in which hydraulic fluid for actuating the brake is pressurized and the piston (20, 90) is displaced by increasing the volume of the pressure chamber (5), and an adjusting device for adjusting the rest position of the piston in the axial direction with respect to the brake cylinder (10), wherein the adjusting device (100) Volume of the pressure chamber (5) changed in adjustment of the rest position of the piston in the axial direction with respect to the brake cylinder (10).
