London: Lewis Hamilton said his early-race battle with Mercedes team-mate Nico Rosberg led to the brake problems that finally ended his challenge in Sunday`s Canadian Grand Prix
Hamilton and Rosberg were locked in a close and dramatic fight for the lead until they both began to suffer from Energy Recovery System problems that also led, in the end, to them losing speed - and Australian Daniel Ricciardo claiming his maiden victory for Red Bull.
"I was following him and when you`re following someone you`re gaining more heat," said Hamilton. "He was in clean air all the time in front.
"There was not much I could do. When I came out in front, everything was cooked already."
Hamilton said he was informed soon after his first pit-stop that both he and Rosberg had mechanical problems.
"We knew as a team that we had some issues in the second stint, but we thought we would be able to manage it," he said.
