Haas returns to Brembo for remainder of race weekend

40

Haas' trial of Carbone Industries' brake system on its VF-17 did not yield satisfactory results, deciding the US outfit to revert back to supplier Brembo.

In a bid to solve Romain Grosjean's chronic brake issues which were centered around a lack of consistency and which plagued the Frenchman last year, Haas sampled the product from Carbone Industrie at the Bahrain is-season test.

The system remained on the VF-17 for Friday's free practice but cooling issues and a request for more time to assess the product have decided the team to go back to Brembo for the remainder of the Russian GP race weekend.

Brake issues remain for Grosjean despite new supplier

Grosjean complained once again about brake problems yesterday, citing a lack of durability.

"We had some issues with the brake on the long run, with the brake pedal going [long] I think we can sort that out, we've got some ideas, but generally the car didn't perform at all.

"But Formula 1 is all about finding the last fine-tuning. We got better recently, we were very happy with Carbone Industrie in Bahrain, but here we're struggling a bit more. So we need to work on it."

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
