Here's a video of the evac taken from a passenger's phone.

I still don't understand why they chose to evac because of a hot brake or how they got a hot brake to begin with? There's gotta be more to the story. The firefighters don't even seem to be too concerned with the gear since they're nowhere near it on the passenger's video. I wonder if the FA's initiated the evac? Odd stuff...
