Hey, I have a trailer that is having air issues somewhere.
This trailer used to always take a long time to build air to release the brakes first thing in the morning, but once the air was built it was fine for the rest of the day.
Now when you have to put on the handbrake (red button) it loses all its air and takes for ever to built air again.
I cant hear any leaks when the handbrake is on or off, and the dash gauges seem fine for pressure.
Any ideas on where to start with this one?
Any help is appreciated.
Trailer brakes, air issues, no audible leaks when handbreak is on.
