I think I understand the system now, the whole thing is mechanical linkage, moving valves that direct fluid that compress the big spring to release the brake and a lack of fluid pressure to set the brake. There is no sign of leakage anywhere that I can see and the power steering works, so it is a failed valve or linkage issue.
Does anyone have a photo of what the linkage setup at the bottom steering column under the Rv looks like? I was thinking that perhaps a small link might have come off.
I cannot lower my jacks to get under there because both house batteries are dead and will not charge, I know the chassis battery controls the jacks but the house batteries run the pump that actually lowers and raises the jacks. Would it be possible to run a jumper from the Pos pole on the chassis battery to the pos pole on the house battery wire that runs to the pump solenoid to control and run the jacks with out damaging anything? The jacks I have will almost raise the wheels off the ground
