DISC BRAKE FRICTION PAD BOLT LOCKING METHOD

摘要

A caliper assembly for a sliding caliper disc brake of the open back type wherein the brake pad assemblies are positioned on opposite sides of the brake disc by a pair of washerhead bolts which pass at their free ends through bores in one side wall of the caliper for threaded engagement with nuts and which pass adjacent their head ends through radially outwardly opening slots in the other side wall of the caliper with the washerhead portions of the bolts received in counterbores which are formed in the outer face of the other caliper side wall and which communicate with the slots in that side wall. With the described slot/counterbore construction, the bolts may be moved axially by an amount to withdraw their free ends from the bores in the one side wall and withdraw their washerheads from the counterbores, whereupon the portions of the bolts adjacent the bolt heads may be moved radially outwardly through the slots in the other side wall while the remainder of the bolts, together with the brake pad assemblies carried thereby, may be moved radially outwardly through the open back of the caliper.
