Hello can someone please tell me where to add alcohol to brakes to avoid freezing in cold weather?

Ear drums as well.

 

Glad hands more in emergency side than service..... pull supply line off back of compressor .....

It’s hard in bits and pieces but it beats being frozen..........

 

Don't put it through the air compressor intake or dump it down the discharge hose if your truck has an air dryer. It can damage the descicant inside the cartridge. If you're going to put it in, put it in after the dryer.

Never use alcohol, it can dry out the seals in the air valves. Use the proper air brake antifreeze.

If you keep up on air dryer/air system maintenance (like draining the tanks often), you likely won't have very many issues with frozen airlines.

 

Long wheelbase trucks with the air drier 10 miles away from the compressor freeze the supply line before the drier........

Ask me how I know this.... quick fix pull discharge line off compressor fill it up air pushes it thru ..... get going......

I Put a new cartridge on every six months anyways.......

 

Even if you don't use trailer parking brake in cold weather make sure you don't have air leaks otherwise TPV will set them for you while you sleep.

 

I remember the older cans of air brake anti freeze said to pour entire contents directly into the air dryer..
Must be before my time- .

Who the heck has an air dryer with a convenient cap on top and easy to access........Terrible advertising

 

^^^^^
@AModelCat is correct. Disconnect the line that runs between the air dryer and the air tanks and pour it in there.

 

Im pretty confident thats on account of the heated air coming out the compressor into that first stretch, having high water vapor that is deposited along the interior of the air piping as it gets cooler with more distance from the compressor and engine bay heat. If you have a trough in the line it pools in there. A straight downward path to the tank would atleast get this condensate puddle into the tank and closer to the drain, with less likelyhood to freeze into a full blockage.

 

I have never ever had my trailer brakes set while sleeping with the engine running, and if it is that cold I would be idling.
Even if they did set after they cooled off and froze, it doesn't matter though, they will not be stuck.

 

With engine running of course you are safe. Common scenario is you parked 6pm, temperature was 34F, wet. Air escaped from the system and red button popped out at 8pm. Still wet. Overnight temperature drops to 20 due to cold front. Have a wonderful morning.
