Haas is to test Carbone Industrie brake discs at the Brazilian Grand Prix in a bid to help work out if its problems this year are down to current supplier Brembo or something related to its own design.
In the wake of Esteban Gutierrez’s latest brake failure at the United States Grand Prix, Brembo and Haas have been working hard on finding an answer as to what has been going wrong this season.
While an interim solution of different brake pad and disc materials has been put in place this weekend, further checks are scheduled for Interlagos next month.
Haas will run Carbone Industrie parts on one of its cars throughout Friday practice to help it obtain proper back-to-back evaluation of the situation. It will then decide if it will keep the parts on the car for the rest of the weekend, or revert to Brembo.
Team principal Gunther Steiner said: “We are testing a different material because we have to also back-to-back for next year, to see what the materials are doing. So then we will see what the outcome is.”
Haas said that Friday’s running at Mexico with the revised brake components had not indicated any potential problems, and Gutierrez said the situation seemed better than last weekend.
“They feel better than Austin, they are reinforced,” he said. “But let’s see in the race. Hopefully it doesn’t break.”
When asked about how the brake failure had affected his confidence, the Mexican said: “We don’t want to have them and, as a team, we are doing our best to put them in the best condition possible.
“It is not a great feeling to go in the car and know that probably the brakes will fail, especially here where we are reaching 360km/h. So we need to really be quite close on that, be aware of that and everything that is going on in the car to not take any risk.”
