    Yeah that's a bit excessive if you're just sitting there parked.

    Check the air suspension leveling valve. The one on the Mack I drive just went bad and it only leaked down when driving. As soon as I came to a stop, it stopped.

    How long does it take to bleed down?

    Or are you worried about the psi settings.

    Is that with the tractor brake set? Try leaving the yellow pushed on. Then pull the red knob.
