Truck mounted brake system with interchangeable lever ratio and replaceable brake heads

摘要

A method of adjusting the lever ratio of the brake system by adjusting the pivot points of the lever to the beam and the actuator elements to the lever. The brake beams each include a pair of spaced beam members connected by weldments which may include actuator mounts, hand brake fulcrum plates and brake heads. The brake head is welded to a back plate welded to the beam member and may be removed from the back plate by cutting the weld therebetween.
