Title: Opinions on air pressure and air up time
Post by: Sebulba on September 09, 2025, 02:57:41 PM

Hello all,

I think everything is functioning properly with me air system, but thought I would run it by you to be preemptive on any issues that may unknown to me.

First pic is pressure when driving.  Is this normal?

Second picture is pressure after sitting for 2 days.  It then took 3 minutes and 33 seconds to air up after sitting 2 days.

Does all of this seem normal?  Does it raise any concerns? 

Thanks

Seb

Looks a lot better then normal!!! Most air brake systems have some leakage, mine goes to zero in a couple of days, might go to 70 PSI over night.

You have nothing to worry about...
