Have you tried putting the coach in a quiet environment, hooking your pancake air compressor to "shop air" and looking for a leak? What tools have you used? In its current condition, your coach does not pass the basic daily brake test & your coach should not be driven until the problem is corrected. If you do not have the ability to find and correct the issue, consider a mobile mechanic.
