Cylinder bore has a lot to do with pedal pressure. That's why it's measured in psi. You change the bore a little and it changes the si(square inches) a whole lot. A couple of guys that know something about brakes have already posted BTW. Even if Mike just knows how and why the components he has work or don't together he's ahead of the game in my opinion. Knowing what's under your butt does a lot for understanding it's and your capabilities.
