I've had problems with this for a while, in the mean time I've been
driving my other car, but a couple years ago I replaced the disc pads
on all 4 wheels of my vehicle. I noticed the front brakes dragging
horribly and the rears seemingly getting no fluid. After some
investigation (on and off while I was at college and driving something
else), I found the brake balancer and put fluid to the rear, to
discover and broken line in the rear. I replaced this and then set
about bleeding the system.
I couldn't bleed more than a half pedal's worth to either rear tire
without the balancer tripping. I know I have no more leaks, and it's
getting harder and harder to have the balancer recenter itself. It
will not do it itself on starting like most cars, even if pressure is
restored, bleeding that valve on the proportioning valve is the only
thing I can do to get pressure to the rear and I have to bleed 3-4
My current situation is all wheels seem to be dragging now, the
rears quite bad, to the point of them really needing a rest after a
mile drive. The rears still aren't connected to the brake pedal
though, upon hitting the brakes I can tell only the fronts are
stopping, I've verified this by jacking up the rears and checking with
someone hitting the brakes.
I've also read something once of a person (diff car) having their
pedal constantly depress slightly on the brake servo, causing the car
to always have the brake slightly applied. He could not figure how to
correct it and put washers under the servo to raise it out a bit and
'recenter' it that way.
Could this be related at all?
I really would like to fix this so I can drive it some,
Thanks a lot,
