How do you adjust spring breaks on a peterbilt?

I cant seem to figure out how to back off the spring breaks? Theres a way to back them off! You put a reciever in the air chamber. But if you turn that so your spring breaks dont work, can you turn it back like say in the summer! When its warmer to work on it? Or will something decide to break in the chamber? Like the springs? If anyone can help me on this i would appreciate it alot! im hanging up on one drum!





Thanks|||On the side of the brake chamber there is a bolt about 4in. long with sort of a T on one end. It's stock through a holder then a nut %26amp; washer is tightened on the other end to hold it. Take this off the side of the chamber it is in the middle (DO NOT TAKE THE BOLTS OFF THE RINGS THAT HOLD THE CHAMBER TOGETHER THIS CAN SERIOUSLY HURT YOU) . I think the one you want is mounted sideways to the two Rings Take the T end of this bolt and stick into the end of the chamber %26amp; turn .You should feel it hook behind something to where you can't pull it out unless you turn it somemore. Get it hooked in and then put the washer and nut on %26amp; start tightening the nut when you can't tighten no more they are backed off. Don't get caught by the dot .I've run em' like that for a long time before . The bolt should be a 1/2 bolt or so, the wrench that fits the nut is a 3/4 or so..The bolts on the rings that will hurt you are 9/16. If there's not one on the chamber look on another chamber all spring brake or double chambers should have or used to have one for towing.|||Sound like you are talking about the spring activated parking brake on an air brake system. The spring retaning bolts can be installed and tightened to remove the pressure off of the springs for an indefinite amount of time with no damage but a random DOT insoection would result in the truck being placed out of service|||If you back off the spring breaks which only work when parked, then what are you going to use when you try and apply the service brakes ? If the brake is hanging up you have to address the issue. Are your shoes worn ? is your slack adjuster set properly? is your " S " cam worn. Spring keys are only used to allow you service the pots or brakes not so you can go down the road without brakes on 1 wheel and endanger others on the road. You will propably find if you do try this as soon as you apply the brakes ,that on that wheel your brake pot will soon be in several pieces and most of them will no longer be attached to the truck. Do you not have to have an air brake certificate where you drive? You should know better if you are a real truck driver. I certainly hope you are nowhere my town on the road.
