Please contact DR. DIFF and let him set you up with one of his master cylinders. I went from a super stiff, ridiculously hard pedal (with a factory bore size); to a firm, smooth pedal with his 15/16" unit. I'm running his Stage 4 'Brembo' kit on the front and Baer's on the rear.
While I agree that the man knows his stuff and sells quality parts, he cannot make up for a mismatched combination. (IF there is one) The 15/16" MC he sold me made no difference because I had a disc/drum proportioning valve despise running a 4 wheel disc setup. I forgot to change it when adding the rear discs and I didn't think to tell DrDiff when I called him.
