Brake master cylinder bore

[Sideways Tim]

I've confused myself, so if you could let me know your thoughts that would be much appreciated. If replacing a master cylinder, what effect will increasing or decreasing the bore size have. My thinking is that a bigger bore will give less pedal travel for the same amount of stopping force?

Thanks, at least I got that straight. What would give the best modulation? Presently they work, but it's a bit all or nothing.
