If you can't release your tandems, you have not enough air in the tank. Since you have problems with your brakes not releasing, you have a frozen valve in the trailer. Air brake anti freeze is your friend now. Remove the red glad hand, pull out the rubber seal and get a good amount of alcohol in the line. That's the easiest way for me if I have issues with a trailer. Put things back together and pump air to the trailer. The alcohol works it's way back.
Best to avoid those issues, REPLACE YOUR AIR DRYER CARTRIDGE ONCE A YEAR.
I keep on hearing the comment "I drain my air tanks blah blah blah". BS. You have to catch and remove the moisture BEFORE it gets in the system and not after it built up in a tank and further down in a valve.

I don't have a choice but to drain my tanks. I'm screwed if I don't.

Last year in Indiana my brakes froze up. I was banging on them. Finally got them to release. Went on my way 30 miles down the road to my pick up. Every once in a while it felt like my trailer brakes would lock up when driving, less than 30 seconds.
Did my pick up which took 30 mins load time. Brakes were locked again. Bang on them again got it to release. Went to weigh.
I notice when I went to move my tandems my button wouldn't release. No air. Brakes locked again.
Was already at Loves. Had the shop looked at it. I can't remember exactly what it was, but it was a relay on the trailer that did the air for the tandems and brakes. It was a simple fix. Longest part of the repair was waiting for the part to arrive.
Hopefully you got it resolved.Drama304 Thanks this. -
If you live in snow country and you have to leave trailers at the door overnight, you learn really quick to get those drums good and hot before you drop the trailer... and we carry big hammers.

Bingo this is the old timer trick ... Ride them to get them hot before pulling in for the night. Works flawlessly.Drama304 Thanks this. -
About 10 yrs ago, running a trailer across 80 from Denver to SLC, brakes kept freezing/unfreezing, did this for 60 miles. Another truck behind me alert me to it on the CB, honestly I couldn't 100% tell because of the ice we were on. I pulled off to check them, he came down the ramp behind me, sure enough you could see random little flat spotting on the trailer tires. Other driver grabbed a bottle of brake line anti-freeze (Air Brake Conditioner and Anti-Freeze), had me set my brakes, pulled the trailer supply line off, dumped about 1/4 cup in, had me releases the brakes, then set them, did this three times. No more brake problems. Ever since, every winter I ask the boss for a quart of the stuff, once temps drop below 30 at night, every container chassis I pull that we don't own, I dump a little in the line before I hook up.

Sometimes it's difficult to figure out whether the drums are frozen to the drum or a valve is stuck and won't release the brakes. In both cases, the brakes are frozen. If there is a second issue like the OP had, it clearly points to a problems in the air system.

It's not hard to figure out a frozen line.
You can hear the air going through the park valve. A clean trailer will air for awhile. A frozen trailer won't air at all. You might get a second or two then stop.striker Thanks this. -
For air line or other deicing, don’t wast money on the stuff you can buy at the truck stop or parts stores.
Just get some isopropyl alcohol, 91 or better 99 percent. Add a few drops of propylene glycol to it if you want.
mix 60/40 with distilled water and put in spray bottle. Got Ice on you windshield or mirrors? Shake spray bottle, spray windshield and wait a minute or two. You will see it start working.Brettj3876, Blue Zombie Trucker and bryan21384 Thank this.
