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.”
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.
For the fifth time in 10 rounds of the 2023 Monster Energy Supercross season, the three riders at the top of the championship standings shared a podium and while those points tell one story, the NBC SuperMotocross Power Rankings after Detroit tell a slightly different tale.
Chase Sexton has been all but perfect during the past 45 days with podium finishes in each of his heats and Triple Crown features. His only stumble during this period was a 10th-place finish in the Indianapolis Main. Last week, Sexton was perfect with wins in both his heat and the feature, although he needed a little help from an Aaron Plessinger mistake to take the top spot on the podium at the end of the night.
Cooper Webb finished fifth at Houston and was beginning to worry ever so slightly about his position in the points. Prior to the race in Tampa, he told NBC Sports that it was time to win and like Babe Ruth pointing to the outfield fence, Webb went out and captured it. Following that race, Webb has swept the podium and earned the red plate two weeks ago in Indianapolis. At Detroit, he added two more points on Eli Tomac as the season begins to wind down.
Tomac struggled with a stiff neck at Indianapolis and after a modest third-place showing in Detroit, he revealed he was still suffering a little. Webb and Sexton have been able to close the gap on Tomac in the past 45 days, but one of the main reasons he is so close in the points was a pair of wins that started the year. Seattle is going to be important for the defending champion because Tomac cannot afford to lose any more momentum with seven rounds remaining.
It appeared Jason Anderson was turning things around. He earned his fifth heat win at Detroit, which was also his sixth consecutive race (including features) in which he scored a top-five. A fall in the Detroit Main dropped him a lap off the pace and sent him home with a season-worst finish of ninth, causing a ripple effect in the SuperMotocross Power Rankings.
Justin Barcia was a huge part of the show last week in Detroit. He swapped positions with both Webb and Tomac in the middle stage of the race, which allowed Sexton to close the gap. Barcia finished fourth in that race to earn his third consecutive top-five. He’s been outside the top 10 only once in the first 10 rounds.
Adam Cianciarulo had a great start to the Main. He led a couple of laps before losing a lap and slipping back to eighth in the final rundown. That run was strong enough to elevate him three positions in the SuperMotocross Power Rankings after Detroit.
The NBC SuperMotocross Power Rankings look at the past 90 days in the 250 class in order to have a balanced comparison between the East and West divisions and Hunter Lawrence has been all but perfect this year. At Detroit, he earned his fifth win of the season and kept alive a streak of podium finishes in six rounds. He tied his brother Jett Lawrence with 10 250 wins one week before the West riders take to the track for back-to-back races at Seattle, Washington and Glendale, Arizona.
The Lawrence brothers are dominating the points in each of their respective divisions, which means the remainder of the field is battling to be best in class.
In the East, that rider is Nate Thrasher, who beat Hunter in a head-to-head matchup in their heat only to finish second in the main when the majority of points were awarded. Thrasher seems to have accepted his position in the championship standings, but that doesn’t mean he won’t keep trying for wins.
Haiden Deegan showed a lot of aggression in his heat last week. He threw a couple of block passes at his teammate Jordon Smith and set up a series of events that kept Smith from making the big show while Deegan settled into second in the preliminary. Deegan was unconcerned about how he raced his teammate and would not let a little controversy keep him from celebrating his second career podium in Detroit.
Jeremy Martin just keeps clicking off solid results. He won his heat last week by making a pass on Deegan and Smith while they were in the heat of their battle. Martin finished fourth in the Main, which means he continues to have only one finish worse than sixth in any of the features or mains.
Smith fell one position in the points standings, but the damage was even worse in SuperMotocross Power Rankings after Detroit. Crash damage in his heat contributed to a last-place finish in that race, for which he earned minimal points. He was not able to advance from the Last Chance Qualifier after stalling his bike in heavy traffic.

* The NBC Power Rankings assign 100 points to a Main event winner and 90 points for each Heat and Triple Crown win, (Triple Crown wins are included with heat wins below the rider’s name). The points decrement by a percentage equal to the number of riders in the field until the last place rider in each event receives five points. The Power Ranking is the average of these percentage points over the past 45 days for the 450 class and last 90 days for 250s (because of the split nature of their season).
