Yes we must wait for the report but I don't think blaming Airbus is correct. They have a set procedure for dealing with a brake failure which if followed correctly will recover braking (albeit accumulator only) but the crew need to be on the ball and act promptly. The comment made earlier that they appeared to turn 180° seems to indicate that nosewheel steering was available - which would seem to indicate that the correct procedure had NOT been followed.
The aircraft only has two engines and if one of those stops working the crew are expected to follow the correct procedure..............
Should be an interesting report.
