one school of thought is; because using mediem brakes, they are applied for a shorter amount of time, thus creating less heat. The other school of thought is, min brakes create less friction. But from basic physics, and i mean basic, the total energy is the same dissipated.
Not quite...
More brake pressure means more energy dissipated in a shorter amount of time, or more braking power used. It also means less time for thrust reversers to work and less time for aerodynamic and other drag to do their work. So, the brakes will dissipate more of the total kinetic energy of the airplane.
