BBC Sport - Formula 1: Paddy Lowe explains Lewis Hamilton's retirement

Paddy Lowe explains problems in Canada

Mercedes' Executive Director (Technical) Paddy Lowe explains to BBC F1 analyst Allan McNish, that the problems Lewis Hamilton and Nico Rosberg suffered in Canada were due to a faulty component in the power unit.

Hamilton suffered total brake failure during the Canadian Grand Prix and was forced to retire, while team-mate Nico Rosberg limped home in second.

Lowe explained the team were able to nurse Rosberg to the chequered flag, and could have won the race had it not been for the Force India suffering similar brake problems and allowing the Red Bull of Daniel Ricciardo to go past.
