Going around is not totally without risk.
A 777 was lost in Dubai. It is something to prepare for and think about.
I go around without question when called. I have also in the past briefed the crew that we would NOT go around from the approach unless the runway, and taxiway, was blocked! (Fuel!)
In the case of the autobrake “discussion” the FO would get a serious debriefing or more later, (depending on company paperwork.)
