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

Knowing the size of the Ultima cylinders will not help you and may even be a dangerous assumption.

The size of each master cylinder needs to match the size of the calipers, size of discs, size of wheels, weight of vehicle etc.

I would suggest you contact the caliper manufacturer who should have some sort of facility for calculating the balance of their brake systems.

+1 you have very different dynamics, master cylinder to slave ratio, size of discs, rolling radius of wheels,and overall weight distribution is a lot to calculate to get right and you really don't want to get it wrong!
Good luck with your project, sounds interesting.

My brakes are completely different to standard so I do not know the standard m/c size sorry.
