[Mgs] Brakes won't bleed

[Dan DiBiase]

Keith, having just done this yesterday, here is what I did (I have regular bleeder valves installed). I started at the
passenger's side rear, with the master cylinder top off. Had my daughter pump it while I monitored the flow. Got
some fluid but not a 'solid tube' into the jar I was using.... So went and did the driver's rear. Same thing. Did the fronts
got those bled out partially as well. Went back to the rear, and this time got it all out. Worked my way around the car
again. It took me 2 (and sometimes 3) tries to get most of the air out, working my way around the car and (obviously)
filling the MC back up after every wheel.

Subject: [Mgs] Brakes won't bleed

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.
