Air Brake System - ejohna2000 - 09-29-2007 07:01
Trying to eliminate some leaks. Found 2 things leaking that are on the
auxilliary air tank. They are listed as #2 on the schematic and are
called Valve,Pressure Protection, 65 PSI MR.
Any one know what there purpose is?? Elmer in Sebring, 86 PT 38

That should be the check valve that isolates/protects the air bags,
step, and aux air fittings (air chucks in the compartment, etc.)
from the rest of the braking system. If the air pressure falls
below 65 PSI this would isolates those from the air tanks so that if
the leak was in that circuit you would not lose braking.

Elmer
Those valves are reasonable and can be bought at NAPA,they have a number on the
unit to identify it.
It is a common problem for them to leak after some aging.
