Pérez keen to rectify brake problems
13 April 2012 – Following his dramatic chase of Fernando Alonso and drive to second place in Malaysia three weeks ago, Sergio Pérez found himself with a selection of gremlins to deal with as Chinese Grand Prix practice took place on Friday.
The Mexican ended his day in 11th position, four positions and half a second slower than Sauber team-mate Kamui Kobayashi.
“The balance of my car had actually been better in the first free practice session compared to the afternoon,” the 22-year-old began.
“I wasn’t too happy in the second free practice. I had problems with the brakes, which didn’t work the way they should, and I lost too much front tyre temperature on the back straight. It was too easy to lock the front.
“We need to improve the car’s overall balance for qualifying. We have a bit of homework now, but we have gathered quite a good amount of data.”
During the afternoon session, Pérez also suffered a huge vibration which was visually evident as his entire nose cone shook violently. Several minutes later, Sauber confirmed that this was due to no more than a flat-spotted tyre.
