brake set up

Hi folks. Had a successful weekend in the work shop and after 4 years trying to little bit here and there the engine is in, wired up and running. So ive decided its probably best to sort the brakes next. Its pretty much original 'build your own sports car for 250" so has cortina front discs and rear drums.
i have a mk2 escort pedal box to fit. without spending to much money what is my best set up for master cylinder and do i need to use the servo? Should i stick with old escort/sierra parts or is there a new cost effective alternative.
cheers

its such a light car that you should not want a brake servo, makes it simpler and a better pedal 'feel' too.

ok thanks. Ive been looking at master cylinders but dont really know what im looking at/for. Do i need a tandem master cylinder and if so what sort of sizes? The original book uses the escort one which has just one outlet. or would i be better off with something like this

A simple Tandem master cylinder is perfect.

If you fit the brakes exactly as they came from the donor and fit a standard Tandem master cylinder of 17-20mm diameter it will all work fine.

The only advantage to having two separate master cylinders is to be able to adjust the front:rear split.

If you do go for two m/cylinders ensure you use two different sizes unless you're balancing them using a balance bar or valve.
Don't do what I did and fit the bigger one to the front (bigger's always better - right? WRONG) - smaller cylinder gives more push so it's smaller cylinder for the fronts, larger to the rear.
