What if it Snows?

Ok, could be this trailer I picked up today. Brakes seem fine. But like I said before, I've been in some cold ### weather for the last couple of days.
My stupid brakes were frozen this morning. That hasn't happened in years

 

Bad valve.

 

That could very well be the case!

 

But how long before I die?
Its not bad at all right now, you really can only hear it when you're parked.
I've got time tomorrow and Sunday to get it looked at, but I'd rather wait until I get home Wednesday.
What would you do?

 

if it's breaks and you got hills I'd have it looked at. But I am no expert.

 

You have air coming out as in you can hear air escaping from the valve or you hear air passing through the valve going to the trailer continuously?

If it's the latter, set your brakes, bring the air up till the gov kicks in, then release your trailer brakes and shut your truck off (no engine noise) and go find the leak outside.

 

Air coming out of the knob.

 

The valve in the dash, behind the knob, has most likely gone bad.

 

A big part of being a driver is having half a clue on how your truck and trailer operates. Being able to diagnose a problem saves time and money.

 

Yup.

Edit: Might could be a bad line or bad fitting as well. I had a bad manifold under the dash on an '89 FLD. That was a pain.
