How to pressure-bleed the brakes on a B-van?

A thumb pump oil can will work a few times like this also with a piece of 1/4 inch clear vinyl tubing and using teflon tape or paste on the outside half of the brake bleeder threads. I almost always push bleed, it works wonder on a complete brake system rebuild, usually don't even have to bench bleed the master cylinder, saves brake fluid as well.

Good tip for when I do a regular bleed job; thanks a lot! For now, though, I need to pressurize them from the front in order to diagnose the problem.
