<VV> flushing out brake lines for DOT 5

[N. Joseph Potts]

Larry -
I have a feeling you're not talking about one of those hand-pumped
Mity-Vacs, here. What is the capacity of this "vacuum tank"? Is it metal?
What do you evacuate it with?

Walter -
I don't think "outgassing" is at issue here. You evidently have in mind here
not PUMPING, but subjecting the fluid to a VACUUM. This can't do any good
unless you can get the gas to separate from the liquid. If you do that, the
gas will be at the TOP of the vessel (brake system). So for this to work (I
still don't think it would, with silicone), you'd have to be able to bleed
the gas off from the TOP. I don't think the bleeder valve is necessarily at
the top of the whole brake line.

Hi Walter,
Sure, but you still need to move the liquid with the air.  I place a
suction tank on the bleeder hole with the vacuum pump on the tank
outlet.  Still moves a lot of liquid to get all the air out.
