    One night I blew an airline on my trailer. I was able to double the line and tape her up, stopping the leak. One brake was locked down tight, a mechanic came out and caged the brake. Since then, I carry a 3/4 inch wrench and a couple of caging bolts.

    You can also back off the slack adjuster.

    Most new cannisters come with a caging bolt attached on the side.

    Next time, instead of double wrapping an airline that you're going to toss, put a dime in where it screws together and tighten it down. Then capture the spring. The compression on the dime will stop air from escaping.

    You can't always back off the slack adjuster. Too much pressure is applied by the spring. All caging does is take the spring brake off mechanically in place of having air pressure to release it. If the brake chamber can be activated with air pressure, the service brake will still work. Backing off the slack totally defeats that brake.

    I wouldn't make a habit of driving with a brake caged. But it may get you to a safer place or off the roadway while waiting for a proper repair.

    I've actually never broken an air line to the chamber, I have had a few diaphragms go though. Can you use the old bic pen trick on those lines? I have a few in my truck just for temp fixes on air lines.

    I was told by a DOT in Wyoming, during an inspection, truck trailer combination is allowed to have one braking position inoperable. That is less than 20% of braking capacity.
    He told me I had one brake to far out of adjustment and he gave me a CVSA sticker.
    Right or wrong I don't know.

    Can you even cage a new brake chamber? I've been out of the loop for a while, but I seem to remember, new brake chambers had that hole where the caging tool goes, filled in. Years ago, I always kept a caging tool in my tool box. And I've heard that too, you can have 1 brake inoperative. I'm surprised they still allow that.
