foot valve air leak
Hey guys got an inspection today by my safety guy where I have a contract with for work. Problem; Air built up to 120psi engine off and no trailer and holding the brake pedal down with brakes released, I have a or had a leak. What ive done, pinched off each line to each brake chamber one by one and held the pedal done. And I can not duplicate the problem when being inspected. Am I missing a step or is this just intermittent. Worse case I could just start replacing all the chambers myself I guess. Thoughts????

Could very well be the chambers. Have someone under there when you have the brake pedal depressed and pin point which one. They should be able to hear it.

Were you hooked to a trailer if so we're glad hands leaking?
