I may sound Dumb! But what do you mean by Ratio?? I don't think the Master is the issue here. I have an adjustable Regulator. I may play with that. And I replaced the front Hoses with the Stainless braided, and I found that the Holes were pretty tiny.. I think I have a pressure loss problem. The Pedal
is hard. Travels not too far down. I have no air in the system. So I will figure it out.
The pedal ratio is the ratio of the distances between your brake pedal's fulcrum, the location of the clevis connecting it to the master, and where your foot goes on the pedal:

If you don't have the proper pedal ratio for the master cylinder you're using, you'll either get too much or not enough mechanical advantage when you hit the brakes. Too much and you'll be annoyed by constantly locking up your brakes, too little and the car won't stop because you can't apply enough force to the master. It makes a HUGE difference if the pedal ratio is off.
