Robert,
<= div>It's a method that is hardly ever used in the field because it is diffi= cult to get a perfect enough vacuum to make it work - there will always be = a little air left in the system.  But at the OEM factories, it is wort= h the extra money to buy a really good vacuum pump.  You can be sure t= hat no one at the factory is under the car letting brake fluid out of the b= leeder screws.  They go to great lengths to make sure that no fluid ge= ts spilled.  It's a method that can work on our planes - fill the rese= rvoir with fluid (not quite full) and pull as much vacuum as possible, hold= for a while and then release.  Might take a few times to get the air = pulled out of the system.  I'll admit I haven't done it - maybe I shou= ld as I've got one brake that is a little bit mushy.  Of course, this method relies on the idea that there are no leaks in the system that = could let in air.

I have never heard of pulling a pure vacuum on the master cylinder = and releasing fluid that will fill all wheel cylinders
properly. See all the methods listed on wikipedia.
