As the title says i am wondering if the factory prop valve is ok to run with the electrical plug unplugged. I redid my car a few years back and have and adjustable valve in there right now but the front two lines are leaking at the T and i can NOT get them to stop leaking no matter how many things i replace or how many times i re-flare the lines. So...im thinking with the cost of a shop to redo the lines versus me just buying a stainless steel prebent kit and redoing all my lines in stainless. Im undecided right now what to do. Reason for the no plug is i dont have it anymore. Im assuming its fine.

 

It controls the "brake" light on the dash board, and measures (within the factory prop vavle) the pressure between front and back and makes sure that it's equal. With it unplugged, I believe the light will stay on.

 

Well i dont have anything right now and no light so i guess it would be fine if thats all it does.

 

Here's a bit more info from the manual:

"The pressure differential warning switch is designed to constantly compare front and rear brake pressure from the master cylinder and energize the warning light on the dash in the event of a front or rear system failure. The valve and switch are so designed that the switch will latch in the "warning" position once a failure has occurred. The only way the light can be turned off is to repair the failure and apply a pedal force to develop approximately 450 psi line pressure."
