OK, quick question. I notice that the air pressure in the system bleeds off after 24-30 hours (a little faster if it is really cold outside). I thought I might have a slow air leak, but I have sprayed soapy water everywhere I can find in the air system and find no leaks. I also did this with the system at 125psi and still no bubbles. The air pressure comes up quickly when the engine is running and I have no issue maintaining pressure even when in the mountains with frequent brake use.

Is it normal for the air pressure to bleed off slowly? I'm not "worried" but an a bit of a worry wart until I know what is "normal."

Thanks in advance for your insight.
