- World championship leader Nico Rosberg looked on the bright side of his Mercedes team's first defeat of the season in Sunday's Canadian Grand Prix where he finished second to Daniel Ricciardo of Red Bull.
The 28-year-old German said that he was pleased with his points haul in a race that saw team-mate Lewis Hamilton after similar problems to those encountered by Rosberg's Mercedes.
"When you lose ERS (Energy Recovery System) it doesn't harvest (heat energy from the brakes) anymore... so that is why the rear brakes overheated," said Rosberg.
"I needed to cool the brakes and lost speed on the straights... so it's still a really good result."
Rosberg said the issues showed that Mercedes still had work to do to improve reliability. "We need to make sure that we are bulletproof," he added.
