The firewall check valves do not last forever! Yes the housing is fine and
I suspect the spring might be also but inside these valves are also a
round/flat rubber disc that can still go bad. Get a few rebuild kits from
Doug and start with the check valves on right side of firewall above the
starter solenoid. 6 years is a long time I believe between rebuild of the
valves especially if your adding air tool oil or castor oil to your system.
They can get gunked up and they are under a lot of pressure constantly.

Oh yes another thing, the seat in the main air valve I don't believe is
stainless, just the pin. Again, these are old systems and a lot of gunk can
gets floating around. It doesn't take much for something to get caught
under a rubber disk in the check valves or under the seat of a shut-off
valve.

| Subject: | Re: Brake air leak |
I got the floor panel off and the leak is coming from a port on the valve in the
right bottom of Dennis' photo. There's a male threaded port on bottom that does
not have an air line attached, and when I apply the parking brake, air continuously
comes out that port.
If the reducing valve is in the top right of the pic, what is this valve? Strange
that it blows out that open port. I'm assuming it is there for a reason and
doesn't need capped.
Thanks for the help!

Remove the brake reducing valve and either replace it or rebuild it. That should
fix your problem.
