Esteban Gutierrez was left disappointed but not downbeat after issues on his Haas VF-16 car limited him to just four laps in practice for the Chinese Grand Prix on Friday.
Gutierrez failed to get out on track at all in the opening session at the Shanghai International Circuit due to a gearbox sensor issue.
The Mexican was sent out at the beginning of FP2 with a packed programme to complete, only to suffer a brake fire after just four laps, forcing him to abandon the rest of his running.
“It was a very difficult day,” Gutierrez said.
“It’s going to be very important to analyze all the data this evening in order to sort out the issues and prepare for tomorrow and the rest of the weekend.
“The team has been working hard and I’m positive that we’ll rectify the situation.
“I’m looking forward to getting back out there tomorrow.”
Team principal Guenther Steiner added: “Challenging day today, especially for Esteban. In the morning we had an issue with a gearbox sensor, which stopped him going out.
“Then in the afternoon, we had a problem with the brake-by-wire system resulting in the brakes seizing and subsequently catching fire. Unfortunately, he wasn’t able to get back out on track as we had to change everything in the backend.
“Hopefully, tomorrow will be a better day us.”
