Romain Grosjean reckons Haas will find a solution to the brake problems that plagued him in Friday's practice at the Hungaroring.
Not for the first time this season the Frenchman was heard complaining to Haas about his brakes.
He told the team that he is "really getting fed up" with the problem.
But despite voicing his frustrations over the radio, the former Lotus driver says he is confident Haas will find a solution ahead of Saturday's final practice.
"It's been a few races we've been struggling with the brakes," he said.
"The first qualy [simulation] lap I struggled with some front-locking.
"The next push lap it was all over the place on rear-locking, I lost it into Turn 1 so I just need to understand to why.
"We're not quite yet on top of it.
"I'm sure by [Saturday] we'll find solutions.
"We always find solutions, so I'm sure we're going to sort it out.
"So far we've always done a great job and moved forward, so it should be sorted."
