1993 Ford Thunderbird SC Q&A

1993 Ford Thunderbird SC Question: I bought a 93 sc and I have no fluid to the back brakes,front works fine, help.

Pressure to porportion valve inlet is there but nothing exiting. -
Answer 1
your going to have to flush break lines and run in fresh fluid. break fluid thickens to sludge when left too long. -
Answer 2
Check for a plunger under a rubber cover on the prop. valve and hold this plunger in while someone pumps pedal. That should send fluid to the rear!! -
Comment 1
Ok is that going to open it up for both lines cause this one has a duel inlet and outlet for the rear alone. -
Comment 2
You know there is one way to find out!! TRY IT. If that dont work out replace the valve and start bleeding the system!! -
Comment 3
you might as well flush it, and run new fluid. if i am right then fluid has thickenned to the point of causing the plunger to not function. -
Answer 3
you may have a plugged line -
