Airk Brakes won't pressure up

[dthollis1961]

John,

There is a safety valve in the system that doesn't allow air to flow
to the accessories until there is about 60 psi on the system. Since
your getting to 60, I'd check the step, air horn and air chuck in
side compartment. When I bought my '78, it wouldn't go above 60
till I whacked the air chuck that was spewing air. My '78 didn't
have an air dryer.
