Stopping Air Discharge while sleeping?

If it's going off that often, you might have a pretty serious leak. Shouldn't be too hard to find if it drains that quickly. Find a quiet corner of a parking lot, charge your tanks up to max, shut the truck off and get out and take a listen. Unless you are completely deaf, you won't have trouble finding it.

If you can't find a leak, then the dryer needs service. Might be the governor.

 

Check your brake chambers as well.

Could also be the trailer.

 

When parked? No way.

Could be in the trailer if he's leaving the brakes released when parked. Hopefully he has tried pulling the red knob allready.

Can he borrow yours?


#### just got weird, didn't it?
Yep.

 

Lol.

 

Also check your fan hub, both of my trucks have had fan hub related air leaks and you can only really notice them when the truck is running.

 

Actually, I just had the same issue. I found my leak when I turned off the truck and then turn the key on for power. The tanks would drain with the power on, but not with the power off.

 

Thats a very common problem.

 

Chase air leaks with a spray bottle with soap and water. Find the bubbles. Easy.

 

In theory at least.
