Sergio Perez says he is encouraged by Force India's pace despite suffering a brake problem during Friday's second practice session for the Abu Dhabi Grand Prix.
Perez was third quickest at the Yas Marina Circuit, behind only the Mercedes drivers, but was forced into the pits during the final 15 minutes of the session after his VJM08B developed a brake-by-wire issue.
"Today has been a good start to our race weekend, despite the brake issue we experienced in the evening session," he said.
"The first session is not very representative of race conditions here, because the track temperatures are much higher than you would have in the evening, so we took the opportunity to try a few test parts that will help us in the development of next year's car.
"FP2 was a very positive session: I felt comfortable in the car from the start and the changes we made worked well.
"Our long run programme was interrupted by the brake issue, but we have plenty of data from Nico [Hulkenberg]'s runs that we can analyse tonight. The baseline set-up we worked on is already quite good, so we're in good shape for tomorrow."
