This is a problem Airbus has been aware of for well over 12 years - can't believe that they haven't resolved it and regretful that it's still causing incidents like this
Also from a moderator I would expect that he admits that the facts are only known when we have an official report at hand.
And yes, it can happen. Although I have never experienced it. FCOM has a by-heart-item in place, that says "no brakes: pull the bypass switch". I guess your airline also has this item. It's only one of four in total, so it would be easy to know it.
Loss of brakes and/or stearing is possible on every aircraft. I wouldn't know of any where it's not. Just because there is an electronical controller for the system doesn't mean it's more dangerous.
