[Mgs] Brakes won't bleed

[Keith G.]

Saturday I got the gumption to get back in the garage and work on my 
'79 B again.  I've had a few niggling things that needed addressed, 
and one big one:  The rear brakes would not get brake fluid to them.

I brought this problem up here before, and consensus pointed to the 
brake master cylinder being the culprit.  I installed a new master 
cylinder and proceeded to retry bleeding the system.  The fronts took 
a lot longer than I would have thought, but eventually they spewed 
air-free fluid.  I was encouraged.

That didn't last long.  The right rear still would not get fluid 
after more than half an hour of pedal pumping.  There *is* a short 
column of fluid in the rubber tube I have hooked up to the valve, and 
it is growing at an imperceptible rate.  I have speed-bleeder valves 
installed, so I don't think that little bit of fluid is a result of 
gravity; I think *something* is happening, but it should not be 
taking this long to pump fluid to the rear brakes, should it?

As if that wasn't enough, I noticed another problem while I was under 
the car.  I'll hit that in another post.
