Shrink seal for the disc brake (円 盤 brake 用 收縮 seal)

摘要

The retraction seal has space in groove wall to prevent retraction seal engaging and nibbling against forward wall during braking. The disk brake (10) has a disk (14) cooperating with opposite caliper (12) by mechanism like pin-assembly (16). The caliper delays rotation of the disk by jointing a pair of friction-pads (18,20) with disk in braking.
