Haas F1 team trying alternative brake supplier in Bahrain test

Brake consistency has been an ongoing difficulty for Haas, which has been working with supplier Brembo for several months n a bid to find a solution.

But it has also arranged to test new brakes from Carbone Industrie at the in-season Bahrain test, which starts on Tuesday.

After running the new Brembo brakes during the Bahrain race weekend, Grosjean declared himself happy but highlighted the length of time it had taken.

"We had an update from Brembo and it worked much better than it was before," said Grosjean, who scored his first points of 2017 with eighth in Bahrain.

"It was clearly a big step.

"It took quite a while to get the update.

"We're going to try something different and see how it goes."

Grosjean, who is particularly sensitive to brake feel, said the update was "a very different story" with an improvement in the "consistency" allowing him to attack.

But having previously said the only solution for Haas's ongoing brake difficulties would be to change suppliers as soon as possible, he remains excited to test the alternative brand.

The team tried products from Carbone Industrie during last year's Brazilian GP and Grosjean was complimentary after testing them.

"I'm looking forward to getting the other brand because last year it changed a lot the end of the braking and the feeling going into the corners," he said.

"Let's see if we still have a lot of improvement.

"There is quite a lot on the menu to see where we can improve the car."
