if you are going to use any pump-the-pedal method to bleed the brakes, you
need to 'bench bleed' the master cylinder first.
( like it simply will not bleed unless you do this simple step first. )
the Vanagon is The Only ( or almost the only )  car that you can bench bleed
the MC in place on the car, by yourself.
As Alan said .......
if using a pressure bleeder, then you don't need to bench bleed, either off
or on the van, first.
