Kelsey Hayes 4 piston discs

exactly why i am asking.I have rebuilt all the brakes and lines,installed the 15/16 master and bled the brakes.Pedal travel seems a bit more than i like.
...my Duster was the same with the 2 3/4" e body calipers.Once i started driving it i found out it stops quickly with very little pedal pressure...like power brakes so i'll wait until i road test the Dart with the Kelseys.
