Piston sizing...

[jeffandre]

Jeff, I would overshoot the rear since you can't increase the rear line pressure unless you have dual master cyls. If you have a single master cyl I'd go for 40% rear bias, then you can turn it down with a prop valve in the rear line.

The multi sized piston Alcons can be compared just calc each piston sq inches and add them up for one caliper half, then compare.

Okay, intended to go dual master for maximum adjustabilty depending upon conditions of brake pads, track, my abilities, etc. (rear prop valve already in car, may or may not be necessary with a dual master?). Got it on the multi-sized piston caliper math too.

Spanky has the right idea as far as going with a combo that is proven, I just got going and want to see it through. I may never do this again, so gotta get it right, so thanks for the help of everyone who has contributed to the brake forum over the years!
