Mickmate is correct. Cylinder bore has alot to do with pedal pressure. The smaller the volume of fluid that you are trying to push through an orvice the less force required. A 1 inch front and 7/8 rear MC was recommended to me for the Corvette brakes in my cars. The brakes were almost non existent. Very scary. I switched them out to 3/4 and 5/8 and the brakes now are fantastic. The pedal travel is almost nil and the clamping force is great. I use 2# residual valves to keep fluid from draining away from the wheel cylinders as my Master cylinders are lower than the wheel cylinders. The residual valves are installed in the brake lines as close to the MC's as possible. For drum brakes use a 10# residual valve.
I use a 2# residual valve in my hyd throwout line as well as it keeps pedal travel to almost zero. John
