    had to switch cascadias at my company. my swap out tractor will lose all air pressure when i park it and go home for the day. the next morning i have to build up air pressure. this happens everyday, is there a way to fix so that pressure is kept? my old tractor did not do this. i have never had this issue in all my years of trucking.

    Yup. Find the leak and fix it.

    First isolate it. Dump the suspension and see if that fixes it. Either way it helps to narrow it down.

    Get out a spray bottle and start spraying. Only so many places that get air when the truck is sitting there turned off.

    The Cascadias I've driven have had an issues with air leakage in two places...the treadle valve on the firewall, and the air bag connections. Hope it's something simple.

    EARS. Ears play a key role in solving this problem lol.

    Funny thing is, it doesn't take much of a leak to bleed your air off.
