   *All* brakes are energy converters hence all brakes can potentially   
   overheat. Brakes, of any type, can only shed heat at a set rate. Exceed   
   the rate of heat input that the brakes can accommodate and you will   
   overheat any kind of brake system.

   I repeat, change your driving habits.

   Once again, change your driving habits. Better still, go take a   
   defensive driving course. Not for your benefit but the benefit of others   
   around you.
