I have a Matlab program that you are welcome to (if you have Matlab). I wrote the program a few years ago to study the braking system. If you do not have Matlab I can run the program with your data and give you some recommendations. It is setup to use a dual master cylinder assembly (like Tilton or wilwood). I need to know everything about your setup.
Wheelbase, cg height estimate, front caliper number of pistons and diameter, rear caliper info, front rotor diameter, front pad radial height (so I can calculate max and min diameters for the pad contact area), same info for rear rotor and pad, pedal arm ratio, weight of vehicle, design stoping rate (eg. 1.0 g's)
What comes out is all info relating to brake application at given stoping rate. It will estimate the weight tranfer, front/rear brake bias, forces on pedal and tire, brake pressures, etc.
It would give you a very good starting point then drive the car and see how it compares, etc. Obviously no warrentee implied or written
