Brake issue caused Hamilton crash

Lewis Hamilton's accident on his first day of Formula 1 testing for Mercedes was caused by rear brake problems, his team has confirmed. The Briton ran off the track and straight on into the crash barriers at the Dry Sack hairpin after just 15 laps of testing on Wednesday. Television footage showed tyre marks running off the track and across the gravel trap, before Hamilton had nudged the barriers, knocking the front wing off.
