Brake energy limits come into play during rejects and most a/c are designed to be able to t/o at max str limit wt and to reject (which is cerified without the use of rev any way) until complete stop using only brakes.(spoilers are allowed ofcourse).consequently in a situation as envisaged above the a/c is defenitely below max to wt. the energy that needs to be dissipated is shared by the revs additionally you normaly would have a longer dist to do it than in a reject.hope that helps
