Brake master cylinder size

[dal2litrefrogeye]

Hi all , bit of a while since I've been on here , i building an Lightweight E Type at the moment . And I've redesigned the brake system , and instead of the E pedal box Ive used a custom made biased pedal box , and seeing my old Ultima used to stop quite well , can someone tell me the size of the front and rear brake master cylinders , and the clutch as well , why we at it ,
cheers .Darren
