Nico Rosberg set the fourth fastest time during qualifying for the Hungarian Grand Prix, but his session was hindered by an issue with his brake balance.
Rosberg's brake balance adjuster became stuck, meaning that the German was unable to shift the brake balance on his hot lap.
"Our speed was a bit of a surprise today as the car set-up work was focused on good race pace this weekend," he said.
"But it worked quite well in the hot temperatures. It's great for the team to be starting from fourth and pole position. I hope we can have a good start even though I'm on the dirtier side of the grid."
"Qualifying did not go perfectly for me at the end, it didn't help that my brake balance adjuster got stuck, so I couldn't change it around the lap. That cost me a little, but the pole wasn't possible today. Now we look forward to tomorrow and I'm confident that we look better in the hot conditions than in the previous race."
