Mark Webber was quickest at Suzuka on Friday’s second practice session.
The Red Bull driver was the last of the front-runners to set a time on the soft tyres and ended the session quickest as each driver seemed to find more time as the session went on.
Jenson Button led the way at first before his time was beaten by Romain Grosjean. Sebastian Vettel and Lewis Hamilton also took turns at the top before Webber claimed the best time.
The session was interrupted soon after it began when Paul di Resta went off at Spoon curve. The Force India driver put his right-hand wheels on the grass approaching the corner and spun into the barrier.
Heikki Kovalainen had made the same mistake moments earlier but got his car back under control on the run-off area. Practice was red-flagged while the Force India was recovered.
That left Di Resta unable to complete any further running. Another driver whose session was badly interrupted was Kimi Raikkonen, who experienced a KERS fault on his car. He was able to return to the track late in the session to set a faster lap time.
As in Singapore with Bruno Senna, Raikkonen was told to get out of the car carefully, not touching it while he made contact with the ground, in case it gave him an electric shock.
With a quarter of an hour to go in the session Schumacher made much the same mistake as Di Resta with similar consequences – his Mercedes ending up in the barriers at Spoon curve.
As the session came to an end Vitaly Petrov had a fright at the first corner as the rear wing came off his Caterham. Fortunately he spun to a stop without hitting anything.
