After Market Brake Systems Help!

[Paladin]

I have a Baer track kit on my 65 fastback, and the problem isn't stopping power, but pedal 'feel'. I have teh right master cylinder bore size and an adjustable proportioning valve, but there is too much pedal travel before teh brakes engage (they are power) and when they do, they grab suddenly making the brakes difficult to modulate. I have braided lines all around. what could I do to get a harder pedal and less travel?? Any opinions greatly appreciated.
