Drum brake with internal and external pads - has disc springs on support bolt to take up end float of caliper

摘要

The pads (13A, 13B) are supported by a caliper (14) which also houses the actuating piston (19). The caliper has a slot (30) which permits it to move radially on its support bolt (26). Disc springs are mounted on the bolt (26) to take up the end float. Also, there is a flexible bellows which covers each end of the slot (30) to retain the lubricating grease.
