Force 10 aluminum brake master cylinder

I have a manual brake Kh disc front 10x1 3/4 rear brakes and a 1 1/32 master and I have 2 " of pedal now.
I am rebuilding the calipers and thought if the aluminum master is the same size I would change it out also.
if you're find with the pedal feel now, then by all means. a 15/16" or even a 7/8" might give better action if that's what you're looking for.

personally, i've found the 15/16 to be about the sweet spot on disc/drum cars on both manual and power applications.
