cpp mcpv1 master cylinder

[kwik_six]

Has anyone out there heard of someone using this on a vacuum car? I planning on doing this with a 1.125 bore .because I believe that what my kit is .I got it from kirbans a few years ago. I think that is what most Monte's use? If any one out there has an wisdom they care to share let me know.

That master has check valves, and proportioning valves in the ports. You already have the prop valve on the frame. You would be including TWO prop valves in the system. Too many problems, That master uses the same pistons as the old Corvette master we use. The 1.125" master would work great IF the motor pulled a high vacuum like a stock V8 could. Putting the large piston on a vacuum booster that has little vacuum will result in a VERY hard brake pedal. You would need a Hydroboost to push this large of a master.
