Disc brake operating mechanism

摘要

An actuating lever (21) of a brake caliper of a vehicle has a cam surface (23) operable against a single tappet (15), and reacting against a caliper bridge (23). The lever (21) includes a wear adjuster arm (33) which exerts a turning moment on the lever (21); this moment is resisted by a small stub axle (34) pivotable in a plain bearing of the brake caliper.
