Kenrodp the propostioning valve will have nothing to do with brake pedal pressure(hard/soft pedal)(I hope you have it plumbed to the rear brakes?? it just stops rear lock up and we seldom even use them) You need to measure the the pedal itself from the pedal pad to the shaft that holds it to the frame. Now measure the point that the mastercyl bolts to the arm up/down to the shaft, divide that number and you should come up with something around 6 to 1. If its 4 to 1(or less) it will really be hard to stop no matter what you do for a booster or cyl. Also if its in the 8 to 1 or higher you will have a long throw on the pedal(not good) Make sure te master is about 1 inch diam piston(now thats a guess /starting point. Also 3/16 lines on the disc(AN3 if braided)Give some more info on the rest of the braking system Like booster size what caliper your using ,line size to the rear and front.
