freio a disco com autorreforço e pastilha do freio para o mesmo

摘要

The brake has an actuating device with a self-servo device and a brake plunger (6) connected to a pad press plate (3) and actuatable by a brake lever (5). An adjuster device compensates pad and/or disk wear. The self-servo device has a pressure pin (4) contacting a front side with an active-sided pad (2) by a split bearing (10) and fixed to a guide plate (9) movably held in a brake carrier (8). The bearing is enclosed by a seal arrangement, when the self-servo device is not working. The bearing has a bearing ball (12) made from hardenable chromium/nickel steel, tungsten carbide or ceramic.
