Quote from The FAA Take Off Training Guide (endorsed by Boeing): “Basically, full brakes must be applied, the thrust must come to idle, the speedbrakes/spoilers must be raised and maximum reverse thrust consistent with airplane controllability must be applied until the crew is assured that the airplane will stop within the remaining runway.” (Appx 3c - viewfoils)
