My friend declared an emegency because of this same thinking and got to watch all the fire trucks greet him when he landed overweight on a 13.000 ft runway.
I would be so glad to see that! I bet he was too. I can't see the brakes from where I sit but the fire crews can, and although I don't know how much overweight your friends landing was, I would suspect that the brakes were very hot and there is a real possibility of a brake fire on any overweight landing.
