What Bore Master Cylinder Do I Need?

Huh? Move more volume thru the same path (brake line) is going to cause higher pressure. The smaller bore has more travel because it takes longer to get same volume thru brake system under less pressure.

That's true but that isn't what I was getting at and never said anything about moving more fluid through a given line size. I was just giving examples of what happens with big vs. small bore size giving the same pedal effort. Moving more fluid through the same line will cause higher pressure but it takes more pedal effort to build that pressure.
