Wayne, how does the pedal pressure feel on your setup?
I didn't plan on running 4 wheel discs, but the rear end I am using is fitted with them so that's how it's going to be. I was figuring that I would need a 7/8" master to keep pedal pressures in a comfortable range...
I have a good firm pedal but not so much I have to stand on it. I'm used to driving a non power brake car, my Mustang is also.
I used a 1 inch so I would have a little more volume of fluid being pushed to the brakes. It also shortens the stroke of the pedal.
