Mark Webber stayed on top of the times sheets in the second practice session for the Malaysian Grand Prix.
But he did not enjoy the same emphatic margin he had in the first session. Jenson Button in second was just five thousandths of a second slower.
Lewis Hamilton backed up his team mate with the third-fastest time ahead of Sebastian Vettel.
Pastor Maldonado set the fastest time early on but he lost time after spinning in the pit lane entry and hitting a barrier. But the damage to his Williams was light and he was able to rejoin later on.
Vitantonio Liuzzi hit trouble in the HRT early on, coming to a halt at turn nine after bouncing over a kerb a few corners earlier. He was also able to return to the track.
The Renault drivers missed the early part of the session as the team worked on repairing the failures they suffered in first practice.
But Jerome d’Ambrosio’s Virgin never made it out following his front-right failure.
