Wait a minute now.  The heat produced is exactly determined by the loss
in kinetic energy.  Energy_realeased_as_heat = .5 m (v1**2-v2**2), where
m is the mass of the car, v1 and v2 are initial and final velocities.

Now there might be some differences between pads in the distribution 
of heat between the pad and the rotor.  I don't know about that.
