Vacuum Brakes Master Cylinder

[mydesigner]

My vacuum brake setup sucks, i can hold no boost but 2 to 4 pounds, i heard somewhere that you could put the master cylinder off a caprice or something and it will raise the pressure. Anyone know?
Anyone have an idea to make it work better? I have s10 shoes, big wheel cylinders, their fine, what can i do?

This thread hashed out alot of your questions. Wanna be the guinea pig? I'm gonna try what I got and then go from there.

So what master cylinder did you go with? Did it help out or what?

Ummm, I put the regular N/A Regal one on. I will see how it performs before going to the Caprice one as a last ditch effort. Either that of a trans brake (break). I need a better trans before I attempt the later.
