Bill,
If you've already heard this ooops, but replace the master cylinder. Mine
was doing something very similar to that. the brakes would work for a bit
and then need two or three pumps to work again. Replacing the master did
the trick

Subject: Weird Brake Issue
Bringing the wife's normally trouble free TR6 out of storage last weekend
brought a surprise: no brakes! I
had flushed the system last spring, so I was really surprised even though
it's been over 6 years since I did
the brakes...
Anyway, the master cylinder was empty. On the large front brake side. But
there was NO evidence of brake
fluid leaking anywhere.
So I refilled the master and set about bleeding the brakes, assuming once I
got pressure back into the
system, I would quickly find the leak. The rear bled fine with no air
evident. The right front also bled fine with
some air evident. The left front simply will not bleed... after 20 minutes
of bleeding I still have more air than
fluid coming out and no pedal to speak of.
I pulled the master to see if it was leaking by at the booster, but there
was no evidence of anything there
either. I reassembled and went back to bleeding. Another 15 minutes and
still air. Then I noticed that on
every upstroke of the pedal, a thin stream of bubbles was coming out of the
master into the reservoir. At
this point I was conivnced I still had air in the master so I proceeded to
pump the pedal to allow all the air to
work itself out. After another 10 minutes of slow pumping, I'm still
getting air every upstroke.
I have not "bench bled" the master... but thought at this point I wouldn't
gain much seeing as how the air is
still coming after all this bleeding... I figure it has to be getting in
from somewhere? And still don't knwo
where the original fluid went.
Ideas? Replace the master?
Thanks!
