Dave,
I just had the same problem while restoring ol' 1343. The Bricklin's valve
is actually a combination valve (proportioning and metering). I took mine
apart and it had two problems. One was a broken O ring on the sliding
piston. There is also a spring (in the part that has a 3/4in. cap on it) with
a cupped rubber seal on the end of it. Mine had a split seal. After I
replaced the O ring and the seal, the rear brakes were fine.

<< Well everyone seams to doubt the proportioning valve is the problem, but it
really looks that way to me. The brakes light is on in the car, and we know
that the drum brakes are adjusted correctly. Its just that a very small
amount of brake fluid (and pressure) is getting to the rear brakes. Lack of
power = power booster / lack of fluid seams to me that the valve has sensed
a drop in pressure and to keep the system running, it has diverted power to
the front and virtually shut it off to the back. It is also interesting
that both rear brakes function (or do not rather) identically. I believe
that I have to reset the proportioning valve - whatever that means. Anyone
else want to shed some light?
Thanks for the experienced tips - nothing beats it! That's why I come here
first!
