Haas F1 team will run the Halo for the first time at this weekend's Brazilian Grand Prix.
The head protection device, which was set to be introduced next year until teams pushed for it to be delayed, has been trialled by most teams during practice sessions this year and now Haas team principal Guenther Steiner has revealed the American team will give it a go at Interlagos.
"We are planning to run it with Romain [Grosjean] in FP1 in Brazil," said Steiner. "There needs to be more testing and we're happy to contribute."
"Even though the halo won't be introduced next year, it's a step toward finding a device that provides protection but also allows drivers to get in and out of the car quickly."
Steiner also said that the team will test different brake products from different manufacturers in an attempt to solve the problems which have blighted their season.
"We will conduct a test in either FP1 or FP2 with a different brake manufacturer," he said.
"It is a test to see how the other material reacts and how the drivers like it or don't like it. We will try to find out as much as possible in the short time we have available."
