You have the basic data available on the internet

Your problem is:

The amount of energy you have to transfer from the vehicle motion and the frequency with which you have to do it.

You have limited yourself to a hydraulically operated disc brake, a conversion of energy to heat and a problem of 'fade'.

I suspect that you need to define closely what you mean by fade, because it looks as if you mean a deterioration in performance generally, rather than the particular prevention of a layer of outgas floating the pad on the rotor.

Look up TRIZ as a way of helping you define the solutions in a useful and innovative way (there are only 40 mechanical principles and 39 contradictions involved in engineering, which have so far managed to cover every single engineering problem and invention known to man)

A typical TRIZ solution might suggest that you reverse the normal arrangement of the brakes for example, with the pads in the centre of two discs expanding outwards, with the outer face of the disc as a large finned surface.( The principle is No 13. "The Other Way Round")

Once you have defined the solutions to the problem, then you can look at methodologies to implement those solutions.

At the moment it looks as if you have already chosen the solution and the method for dealing with it and are just looking for figures to justify your answer and create the problem.

(Another solution. A pump can absorb a huge amount of energy. Use the axle motion to pump the hydraulic fluid, use a fraction of the pressure to power the brake pads and 'waste' the rest of the pressure by returning it to the catchment tank. Now the problem is to design a way of not pumping when the brake is off.(Clutch?). If you loose the hydraulic pressure by expansion, you will create a refrigerator effect that can cool the brakes too.

Principles 17, "Another dimension"; 22"Blessing in disguise" , 34 "Discarding and recovering"

It might not be the result your tutor was expecting, but at least it might be an original approach!
