Ah yes the failing brake argument....that brakes are perfectly reliable for landings, but during RTOs your brake disks turn into marshmellows...but not on landings...only RTOs.
Exactly correct, because at 400t TOGW [B744] and RTO brake application 10+ Knots beyond V1 you're in La-la-Land....the total available brake energy will be dissipated BEFORE you get to the end of any "extra" pavement. But during landing at 285t Max Ldg Weight [115t lighter] your brakes will NOT fail.
