Just curious if you ever found a proportioning valve that worked? I assume so since the car has been out and about.
I ran into an issue earlier today with my '87 while loading it onto a trailer where the brakes gave out on me and I got to roll off the trailer without any brakes. Luckily I was able to jamb the pedal as hard as I could and got it to stop before hitting the house.
I have one of those brass proportioning valves and tried tightening all of the lines going to it but still have a leak. It appears to be coming from the plastic pressure switch. Not sure exactly what I should do here if the majority of these valves are defective. :(



Thanks,
