Haas still working on brake issues

Haas admit that it is still working on the brake issues that have been hampering its season. Romain Grosjean has consistently been heard complaining of problems when he hits the left pedal, while teammate Kevin Magnussen has been able to work around the problem. The team are still looking into a solution to the complication.

Last time out at the British Grand Prix, Haas split brake suppliers between its two drivers, with Grosjean riding with brakes from new supplier Carbon Industrie and Magnussen with Brembo. Team principal Guenther Steiner said progress was made but they are still yet to get to the root of the problem.

"We made one step toward understanding the new brakes," Steiner stated. "There is a second step because in Silverstone there is no hard braking. It's one of the circuits where you use the brakes less than in all of the other circuits.

"Hungary is the opposite. You use the brakes quite a bit and you have no time to cool them down because there are no big straights. You need to get your brake package in the right window so you're not putting too much energy into the tyres from the brakes.

"The driver just needs to always see that he gets them in the window," he continued. "Especially in qualifying, so when you cross the finish line for your fast lap, you have the right temperature in them. So we continue our testing and see where we get in FP1 and FP2, and then decide what we are going to do for the race.

"We will only know that after FP1 and FP2 because we are in the phase of evaluating and testing brakes. It depends a little on the driver feeling. At Silverstone, Kevin preferred to stay with the Brembo brakes because he knew them better. He did not do FP1, so he was more comfortable with them. But again, I don't know what will happen in Hungary until after FP1 and FP2."
