Sebastian Vettel was quickest in the first practice session for the Hungarian Grand Prix as the Red Bull drivers headed the times.
Vettel set a best lap of 1’22.723 when he returned to the track in the second half of the session. He sat out much of the early running when a brake problem was discovered on his RB9 during his first run.
Kimi Raikkonen was third quickest but also experienced a series of niggling problems in his Lotus. A brief airbox fire was extinguished but Raikkonen then complained of having moisture in his footwell.
In the final minutes of the session he was told to slowly return to the pits as his right-rear tyre developed a slow puncture.
Romain Grosjean was also well up for Lotus, within a tenth of a second of his team mate, the pair separated by Fernando Alonso’s Ferrari.
Jenson Button was an encouraging sixth for McLaren ahead of Adrian Sutil, with Nico Rosberg the highest of the Mercedes drivers in eighth.
The top ten was completed by Sergio Perez and Pastor Maldonado. The session ran in hot conditions with track temperatures reaching 45C by the end of the 90 minutes.
Jean-Eric Vergne had a high-speed spin at turn four but managed not to hit anything, and Jules Bianchi lost some running earlier in the session with a KERS fault.
