Pressurizng the system will require you to go back and forth to the master cylinder and the bleed value. I think you might find that one a bit harder to work with.
I didn't hook it up to the master cylinder I hooked it up to the bleed valve and brought the vacuum up to 25 psi then opened the valve until the fluid came out with out bubbles.
