Brake material is cause of problems - Grosjean

40

Romain Grosjean believes that the brake material used by Haas is the root cause of the multiple brake failures suffered by the Frenchman recently.

The problem came to a head last Friday when Grosjean endured another problem in free practice in Suzuka, subsequently saying that the issue was "unacceptable" and "dangerous."

While the Haas driver enjoyed a relatively trouble-free race on Sunday, he insisted the Brembo brakes remain a problem.

"I think it's a material issue, said Grosjean."

"I'm very sensitive to the brakes so they can improve and that would help everyone. They are going to work and hopefully they will find a solution."

Team boss Guenther Steiner also underlined the fact that the brakes were not consistent enough, which in turn has an impact on a driver's confidence.

"It's not good enough and the biggest thing is if they work, they work fine but they're not consistent so you assume they work badly," explained Steiner.

"It's a strange thing to explain. If you know they're working good then you can brake at the last centimetre.

"You have always a buffer in there and then you realise you could've braked later but you cannot because if they are inconsistent or they don't do what they should be doing, you are off like we had in practice.

"You keep on working, it keeps us in our jobs!"

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.
