Brembo cites disc issue for Gutierrez’s USGP retirement

Leave a comment

AUSTIN, Texas – Esteban Gutierrez felt a brake issue was the primary culprit for his retirement on Lap 17 from Sunday’s United States Grand Prix, and Brembo has confirmed this was likely a disc issue.

Brembo released a statement regarding the retirement:

“In relation to what happened to the driver Esteban Gutierrez of Haas F1 Team during the United States Formula One Grand Prix, Brembo regrets that the withdrawal of the driver at the end of lap 17 was caused by a possible issue connected to the braking system.

“After a first analysis of our technicians present at Austin, it would seem that in correspondence with the front left wheel a problem in the dragging area of the disc has been identified.

“It will be Brembo’s responsibility to carefully investigate, in collaboration with the team, the causes that led to the technical issue.”

Haas has had a number of brake-related issues this year, but team owner Gene Haas reiterated a commitment to Brembo over the weekend.

Gutierrez told NBCSN’s Will Buxton after the race he thought for sure it was a brake failure.

“Yes, it was,” the Mexican said in the immediate aftermath. “We think one of the discs broke. Not what we wanted for a race weekend. Not easy to accept either. Difficult start of the weekend and it was not going to be easy. We went on. We did a great qualifying, optimizing what we had. We pushed to the maximum. We got into the top 10 the first few laps. Aggressive strategy. At some point lost the brakes. Fortunately didn’t run into the barrier (in Turn 11).

“It’s very disappointing but we have to continue focusing on the positives. I want to thank everyone for the enthusiasm and support all weekend. I’m sorry for all of you who were here to support us and ensure we are doing our best.”

Gutierrez’s teammate, Romain Grosjean, got a point on Haas F1’s home soil with 10th place.

Coincidentally, I guess, I caught up with Brembo F1 brake engineer Andrea Pellegrini earlier this weekend on Friday, who explained that Circuit of The Americas is a low-energy braking circuit, and only requires more braking capability than Silverstone, Spa, Suzuka and Interlagos.

He explained the initial temperature of the carbon brakes is about 400-450 degrees Celsius, with a peak temperature of over 1,000 degrees.

“You don’t want it too high to avoid the wear, and not too low, because it’s complicated. There’s initial bite and friction. Every disk has a special cooling dedicated to different circuits. Austin is a medium circuit in energy for the brakes,” he told NBC Sports.

F1 tests: Mercedes innovates with wheel adjustment system

MONTMELÓ, Spain — Veteran Kimi Raikkonen set the fastest time on the second day of Formula One preseason testing on Thursday, but Mercedes still garnered more attention by introducing an innovative wheel adjustment system.

On-board footage showed defending champion Lewis Hamilton pulling the steering wheel back and forth on the front straight to apparently change the angle of the front wheels on his Mercedes car.

The team stayed tight-lipped about the car’s new feature but guaranteed it was “safe” and “legal.”

“I probably won’t shed a great deal more light than what you saw on the TV but yeah we have a system in the car, it’s a novel idea,” team technical director James Allison told F1 TV. ”We’ve got a name for it, it’s called DAS, if you’re interested, and it just introduces an extra dimension for the steering, for the driver, which we hope will be useful during the year. But precisely how we use it and why we use it, that’s something we will keep to ourselves.”

Allison said governing body FIA knew in advance that the team was introducing the new system.

“It’s something we’ve been talking to them (about) for some time,” he said. “The rules are pretty clear about what’s permitted on steering systems and we’re pretty confident that it matches those requirements. I’m pleased we got it on the car, it seems to be useful, and we’ll see over the coming days how it benefits us.”

Hamilton said he was still trying to get used to the system, but praised the team for coming up with the innovation.

“I’ve only had one morning on (it, so) I don’t really have a lot to talk about with it. We’re trying to get on top of it, understand it, but safety-wise no problem today and the FIA are OK with the project.

“For me it’s really encouraging to see that my team is continuing to innovate and stay ahead of the game, and I think that’s down to the great minds in the team and so hopefully that’ll work to our benefit.”

Hamilton led the time charts on Wednesday but was only ninth-fastest on Thursday.

The 40-year-old Raikkonen, who has a chance this season to break the record for most race starts in F1, was fastest with a time of 1 minute, 17.091 seconds in his Alfa Romea. He was 0.2 seconds quicker than Sergio Pérez with Racing Point. Daniel Ricciardo of Renault was third.

Raikkonen caused a red flag near the end of the afternoon session when his car stopped on the track with an apparent mechanical issue. The Finnish driver had spun earlier in the session, as did Valtteri Bottas of Mercedes, Romain Grosjean of Haas and Pierre Gasly of Alpha Tauri, formerly known as Toro Rosso.

Grosjean had the most laps among the 13 drivers who went to the track on Thursday, with 158.

Bottas was the slowest driver of the day, while Sebastian Vettel was sixth-fastest with Ferrari.

Pérez had set the quickest time in the morning session. The Mexican driver had been third fastest on Wednesday, behind Hamilton and Bottas.

Drivers will be back on the track on Friday to close out the first week of testing. Teams will have another three days to test next week.

Preseason testing has been reduced from eight to six days to help compensate for the record 22 races on the calendar, including a new Vietnam Grand Prix and the return of the Dutch GP. Midseason testing also has been eliminated.

The season opens on March 15 at the Australian GP.

The Barcelona-Catalunya track will host the Spanish GP on May 10.
