    Yeah mechanic came and fixed it. Even he said it was weird that it acted that way. He just drained the trailer air tank (I am glad I watched him do it as I had no idea where it was located and now I can do this myself next time). After he drained the tank my brakes worked. It took a while for my tandem pin pressure to build back up due to the ice in the lines, but I am good to go now. I will get that brake antifreeze thx everyone. I love learning new things.

    Something old timers told me when I started driving. In winter, don't lock your trailer brakes when you stop to sleep, eat, etc. Just lock down the tractor.
    Saw a fellow one day dragging a trailer down the interstate with frozen trailer brakes. His trailer tires on the passenger side were gone down to the rims in one spot. Made a hellva noise!

    one thing I see a lot is when bob tailing, the air lines are lying on the catwalk. this allows water to get in them and then when you hook up to the trailer you pump water into the lines.

    HANG THEM UP PROPERLY. on the back of the cab

    Just out of curiosity, r u sure the pads are not frozen to the drums? new trailers shouldn't have any water in the lines. however if it was driven down the road during wet conditions then parked, pads can freeze to the drum by either rusting or actually icing. Put your tractor brakes on, release your trailer brakes then take your hammer and hit the pads on the steel edge. May take a few hits, if you see them release, then that's the real problem. You'll have to do each wheel. Pins pull the air supply from the same source, just different feed.

    That old timer would be correct. Serious ....people actually have to be told not to use rubbing alcohol? Cripes Almighty!

    Years ago rubbing alcohol was the standard thing to use when in a bind, out in the middle of nowhere. Just not the green stuff. Plenty of people had a bottle in their side box.

    You can make a homemade icepack using alchohol and water, don't remember the proportions at the moment, but it does work and the ice pack will not freeze solid when you put it in the freezer.

    wow never knew, only known guess what we call heat. They didn't sell rubbing alcohol in the gas stations either, lol, so I guess we didn't have to think about it.

    The older rubbing alcohol was, showing my grey again, isopropyl alcohol, and wouldn't do the damage to rubber parts that methanol or ethanol would do.

    The company mechanics used to charge the tanks with some anti-freeze, but there are warnings about the stuff damaging parts of the braking system on some newer trailers.

    It's better to drain the water from the tanks unless that won't work.


    The shop made caps for the glad hands on trailers so they wouldn't get water in them while washing them(poultry trailers).

    What usually happens is the spring brakes come on when the lines freeze and the supply tank loses too much pressure, I've been under a few to get them to a shop when that happens, but not lately, a good air dryer on the tractor prevents many problems.


    Lots of things happen with poor maintenance. I could write a book, and I've only been at this for 9 years.
