How to Measure a Brake Chambers: Brake chamber size can be determined by measuring the diameter of the clamp used to hold it together or by locating the size markings on the brake chamber. The most common brake chamber size is 30. However, there are vehicles using both smaller and larger sizes. For example, sizes 16, 20, 24 and 36 brake chambers may be used.

CAGING: WHY & HOW / CUTTING A PUSH ROD
Caging brakes is only done when an air brake system failure has happened and you need to get your unit to a safe haven only, not normal operation. This procedure releases the spring tension within the brake chamber and will render that wheel with no brakes when completed. • To do this, crawl under truck or trailer and find brake chamber to the wheel with brakes you want to release. • On the chamber itself, you'll find the internal hex pipe plug. It'll 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'll be compressing that spring by hand. • At this point, your brakes should be released on that wheel. If not, continue to turn until released
Remove Dust Plug

Spring Brake (Service Side)
Remember, this procedure is not for normal operation, but to get to a safe haven where repairs can be performed. Stay safe out there!
