Romain Grosjean says the brake failure which put him out of the Malaysian Grand Prix happened without warning.
The Haas driver spun into a gravel trap at turn 15.
“There was a brake failure,” he explained. “We really don’t know what yet, but the pedal just went straight to the floor and I had to avoid the car in front of me.”
“Our data didn’t suggest anything beforehand,” he added.
Grosjean said he was running strongly before the failure. “We did a really good first lap and we were looking at points running inside the top ten.”
“Things just didn’t go very well. I was racing with Fernando Alonso. He had power, so it was very difficult to keep him behind. I was then just trying to follow his pace.”
“The plan was to try to keep the tyres alive for quite a while. We just didn’t get to that point, though.”
Both Haas drivers retired from the race: Esteban Gutierrez dropped out when a wheel came off his car.
