" Getting wrapped up in it " wasnt directed at you, sorry you took it that way.
What I was trying to say, was as a whole, many people get all wrapped up in the bore thing.
I have used different disc MC's, and in my experience, they all feel the same.
Not using that size MC, but the theory is the bigger the brakes and pistons, the bigger bore and volume MC is needed.
a 1/16" inch increase in master cylinder bore size requires a 12% increase in leg for the same pressure
a small 15/16" master and a 'cuda 2 3/4" caliper piston will stop effortlessly,almost like power brakes.
..if you go from 15/16 master to 1 1/16 you will require 24% more leg
Exactly backwards
smaller master increases pressure but increases pedal travel .
15/16 bore master and 2 3/4 piston (cuda caliper ) on an a body will stop effortlessly
1 1/8 bore master and 2 5/8 piston (a body caliper) will make stopping very difficult
a 1" master with 100lb of leg will produce about 3600 psi with the a body 2 5/8 caliper
a 1' master with 100lb of leg will produce about 4400 psi with the e body 2 3/4 caliper
a 15/16 master will increase the pressure even more but there will be a bit more pedal
travel.
use the small master and larger disc caliper and you will have great brakes.
