On mine the Front charges up and front brakes work. (Sounds). The rear must be the red since that needle is lazy and doesn't want to get up. Also the rear brakes won't release as there is no air in one of the front tanks. It all worked "when parked". Having said that, my next project was to drop the wet tank and go through it replacing the check valve on it and the auto drain. I can't move the coach unless I uncage the rear brakes. At that point it's gonna be a mobile mechanic call.

I did my last Hail Mary by dumping the air. Rear tank and needle are lazy to get up and running.

My ultimate test will be to bring shop air into the rear service port and see if that wakes anyone up.
