Opinions on air pressure and air up time

[Sebulba]

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...

Might need to replace an air bag or two.

 1 side dropping is a leveling valve 95% of the time,do the simple DOT test build your air pressure up kill the engine , hold the brake pedal down for 60 seconds if drops over 4 lbs you have a leak in the brake system, if that passes, then if it drops your leak is the suspension system ,leveling valves are terrible about leaking and dropping one side
