Touch and Go?
If they had carried on with the original approach, could they not have simply turned it into a touch and go if they found the brakes to be inoperative when they pushed the pedals?
I suppose there was a chance that's the brakes could kinda half work, enough to prevent returning to flight. I can see an argument for not touching the ground so that you can get the airport prepped for a tricky landing after a second approach.
