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.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.
Yes that is correct.A little help for you since you linked their home page. I assume this is what you’re referring to.

That one is good if you have a power brake booster or like a rock-hard pedal! You may want to consider a 15/16 bore master cylinder. A little more pedal travel but much better braking! Just my 2 cents.
Do you have a force 10, Dr diff or late model store bought? I like my firm pedal and it is not hard to apply brakes at speed also.I have an aluminum 1-1/32" bore master on my 68 GTS with SSBC aluminum calipers in front on KH style replacement rotors. Rear brakes are stock. It stops excellent from over 130.
