I have a 70 GMC half ton with 6 lug 4 wheel drum. I would like to add a power booster to make stopping easier. The question is If I add a power booster and corvette style master cylinder how to I plumb in a adjustable proportioning valve? I was told by the supplier to add it in the line that goes to the rear brakes. Makes sense but if its a dual master cylinder, how does it proportion the fluid? Also do i need to add the residual pressure valves to keep 10lbs of pressure in the lines? My head hurts!!
Thanks,
Mac
