More then two sources confirms already brakes malfunctuion. At forumavia smb PsychoKif claims that he has CCTV overlooks rwy. He saw that touchdown was ok and first couple of seconds it ssems that aircraft begin normal deceleration (there was no smoke from the wheels, but it was far and not very clear) but then it seems that there was no brake power and a/c run till the end of the rwy.
