Disk brake

摘要

An open-topped disc brake comprises a disk and friction pads provided on opposite sides of the disk and having back plates. A caliper having a window and fluid pressure cylinders are provided together with pad pins extending across the window for supporting the friction pads. Pistons slidably received in the fluid pressure cylinders urge the friction pads against the disk. First and second shims are disposed between the friction pads. The first shims are provided near the friction pads with first claws provided on the first shims which resiliently embrace the back plates of the pads by straddling outer and inner edges of the back plates. Second shims are provided near the pistons with third claws provided on the second shims to detachably and resiliently engage the pistons. Second claws are provided on one of the first shims and the second shims for resiliently gripping the other of the first shims and the second shims so that the first and second shims are moved together.
