i have a 94 ranger, having brake issues. had to replace one of the lines going from the master cylinder to the proportioning valve. Im not too sure if this was a prior problem, i think it may have been. Onto the issue, i have front brakes bled both sides no issues. I then went to the rear, driver side has nothing coming out and the passanger side has just a drip coming out. anyone with some insight on where to go or what to replace would be greatly appreciated!! leaving friday for carlisle and need it fixed by thursday thanks for the help everyone

 

If memory serves correctly , if the proportioning valve is out of fluid , the line needs to be vacuum bled. You can't do it by the pedal method.
Someone on these forums had that problem years ago but I am unable to locate that thread.
