MBdoc is pretty much on target
I think he was showing the heat build-up during hard stops verses drawn out pedal action giving the rotors time to cool as you release the brakes. I think either way if you can manage to keep your foot off the brake except when needed, they're going to last. I just hate following anyone who rides the brakes cresting a hill, then braking down each hill. Heaven forbid if we exceed the speed limit by 10mph on a down grade, let's waste the brakes.
Constant hard braking has a tendency to warp rotors as the heat can't dissipate quick enough.
