Abstract
The pull- or push rod of a brake linkage, preferably in the form of a brake clamp, features a double spindle (21) whose oppositely directed threaded ends (20) are screwed into nuts (14) which have a self-locking thread and are hinged to brake levers (4). A flat spiral spring (23) continuously loads the double spindle (21) in the direction of rotation for brake clearance adjustment, while a rotary lock keeps the double spindle (21) in place when the brakes are released. Upon achievement of an application stroke or pressure, for the brakes, the rotary lock is released, and by turning the double spindle (21), excessive play of the brakes at the beginning of the braking process is compensated immediately and completely.
