Jag overcomes brake problems

Jaguar saw its running time cut short in Friday's first free practice session for this weekend's German Grand Prix after suffering problems with the R5's brake ducts

Christian Klien and test driver Bjorn Wirdheim had their brake ducts changed and while Mark Webber reported no problems on his installation lap, the team decided to change his as a precaution.

"I did my installation lap this morning and was due to go out at the end of the first session when the team took the decision to change my brake ducts," Webber (13th) said. "They had found a problem on Christian and Bjorn's car and to ensure that they did not cause me any difficulties they changed them too. I had a good second session this afternoon and managed to complete 27 laps working through a fairly comprehensive programme. We will be concentrating now on our balance and some further tyre work ahead of tomorrow's qualifying."

Klien, who was told by his bosses at Jaguar ahead of this weekend that he must show his potential by the end of the year, was two places down on his team-mate in 15th spot.

"The track is quite green out there but the car is feeling good," said the Austrian. "My programme in the second session was very busy as I was making up for lost time. We did manage to complete our test items though and I am looking forward to getting back behind the wheel for qualifying tomorrow."
