Low AIr Pressure

{"text":"So I am experiencing tractor air pressure that is abnormal. No air leaks, but the tractor air pressure sometimes drops low enough for the red indicator warning to display. The trailer air pressure stays at 125 while the tractor pressure is all over the place. (2018 Cascadia)\n\nAny ideas? I would hate for my brakes to lock up....","videos":"[]","link":"{}","pics":"[]","canComment":true}
