freezing brake lines question

If you service your air dryer annually like you're suppose to, odds are you never will have that problem.

 

Usually you just disconnect the glad hands, pour the fluid down into the glad hand hose. Couple of tablespoons worth perhaps. Reconnect lines, air it up, and it should work its way through the system.

 

put it in the emergency line

 

Grab a bottle of abc at the next truck stop. Air brake line conditioner. Fill the red line and reattach. Then pop your red brake button a few times.

 

Here's a pic of the bottle

 

Don't place your detached glad hands in your spare tire where a few gallons of water collects

 

don't leave your glad hands disconnected, PERIOD.

moisture in the air can get in either the trailer or truck. and freeze up. the holes in them lines aren't very big.

if you push the trailer valve in and nothing fills up the trailer. immediately. it's a good bet the truck itself is froze.

if the trailer fills but its very fast. it's probably a froze trailer.

don't know about the rest of you all, but more often then not. it's been my truck.

 

It's not just the trl icing up that you have to worry about my air dryer froze up Monday morning. For trl you pour in the supply. If the air dryer freezes and the truck won't build air you pull the main line at the compressor and dump a bit down there. It'll work it's way back and unfreeze in about 5 mins. To get the truck to build air you may have to cover the air dryer pop off valve with your hand though. I need a new air dryer had mine rebuild a year ago but the only thing it's good for is target practice. I drain probably 1/2-1 gallon of water out of my tanks each week.
