[Vwdiesel] Not Deisel, just brake bleeding hell on a VW bug question

[Patrick Dolan]

Pressure bleeding just counts on the bubbles being at the high point (where the bleeder is located) or going to that point and being washed ot of the system by being carried with the flow.   You can't put enough pressure on a system to reach miscibility point.

Vacuum does work just as well (even better) because the bubbles become physically larger and less dense (you won't reach a significantly low pressure, so there is in fact still a fair bit of absolute pressure in the bubble - i.e. significant mass).

Done carefully, both work.
