CAGING: WHY & HOW / CUTTING A PUSH ROD
Caging brakes is only done when an air brake system failure has hap- pened and you need to get your unit to a safe haven only, not normal op- eration. This procedure releases the spring tension within the brake chamber and wi l l render that wheel with no brakes when completed. • To do this, crawl under truck or trai ler and find brake chamber to the wheel with brakes you want to release. • On the chamber itself, you'l l find the internal hex pipe plug. It'l l be mounted on the clamp of the brake chamber. Remove the nut, washer and tool from the holder. • Remove dust cover from brake chamber • Insert caging tool into chamber and turn 1/4 clockwise to seat the tool • Insert washer and nut • Tighten to about 2.5 inches of caging tool exposed. This is hard work as you'l l be compressing that spring by hand. • At this point, your brakes should be released on that wheel. If not, continue to turn unti l released Remember, this procedure is not for normal operation, but to get to a safe haven where repairs can be performed. Stay safe out there!
