Hi all.
Many thanks to all who have made suggestions re: my brake problems.
As it turns out, the right rear brake line was about to burst, with a
big fat bulge in it (thanks for that suggestion, Bill D.), so I
replaced it with a spare I had. I get no braking action from the left
rear, but can bleed fluid there. That side brake line looks pretty new.
So I'm suspecting the caliper is bad on that side. However, I've now
discovered that all three working calipers are binding after braking.
they bind, then after a while relax. The odd thing is that they only
bind when the car is running. If I roll down the driveway with the
engine off, they don't bind. I'm wondering if this suggests the problem
is in the servo/slave binding up, or if I could have a problem with my
recent master cylinder rebuild? Or if this may have something to do
with the brake failure switch at the 5-way junction. Ruth Burgess
described its function to me the other day, but I don't know if it
would serve to prevent fluid from backing off and releasing the
calipers for some reason?
When I first depress the brake pedal, I get full action, as if the
servo is working. When I let up and depress the pedal again, I get a
hard pedal at the top of the stroke--very little movement.
Any thoughts?
