Force 10 aluminum brake master cylinder

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

Yes that is correct.
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.

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.
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.
