How Red Bull’s McLaren-Inspired Brake Upgrade Fueled Verstappen’s Monza Dominance and Could Shake Up the 2025 F1 Title Fight

When Max Verstappen stormed to a dominant victory at Monza, many fans and pundits were surprised by the sheer margin of his success. But for those paying close attention to the technical nuances in Formula 1, this wasn’t just a fluke. Red Bull’s secret weapon that weekend wasn’t merely raw power or flawless strategy — it was a clever, under-the-radar upgrade inspired by their rivals: the McLaren front brake duct system.

The Hidden Upgrade That Turned Heads

Unlike the highly publicized aerodynamic tweaks and power unit adjustments documented in the FIA’s upgrade package, this new brake system flew under the radar. Yet, its impact was undeniable.

Brake ducts, those seemingly minor yet vitally important cooling channels, play a crucial role in managing the enormous heat generated in braking zones, especially on a track like Monza. What Red Bull did was adopt a front brake cooling system closely resembling McLaren’s setup, known for its superior tire management and efficient heat dissipation.

This subtle technical evolution was the key behind Verstappen’s incredible race pace and reduced tire degradation, traits that had traditionally belonged to McLaren throughout the 2025 season.

Why Brake Cooling Matters

At first glance, brake ducts might seem insignificant compared to aerodynamics or engine power, but in reality, they’re a pivotal element of a car’s overall performance.

Formula 1 cars generate immense heat through heavy braking zones, and if the brakes — and by extension the tires — overheat, it can lead to excessive tire wear and reduced grip. Efficient brake cooling means the tires maintain their optimal operating temperatures for longer, enhancing consistency over long stints.

Monza’s high-speed straights followed by brutal braking zones are a perfect storm for brake heat buildup. Red Bull’s revised brake duct system tackled this by channeling airflow more effectively through two critical cooling outlets, mirroring McLaren’s design philosophy.

A Side-by-Side Look: Red Bull’s Brake Evolution

Examining the visuals of the RB21’s brake ducts before and after Monza reveals a dramatic overhaul. The original XandV spec ducts have been replaced with larger, more optimized cooling outlets, positioned to maximize airflow and heat dissipation.

This upgrade isn’t just about raw cooling — it’s about strategic thermal management. By maintaining lower brake temperatures, the system indirectly protects the tires from overheating, allowing Verstappen to keep his pace high and degradation low.

The Race Pace Advantage: Verstappen vs. Norris

The proof was in the numbers. Between laps 5 and 35, while both Verstappen and Lando Norris were running on medium tires in clean air, Verstappen maintained an average lap time advantage of approximately three-tenths of a second per lap.

More importantly, Verstappen’s tires degraded much less than Norris’s, highlighting the tangible benefits of improved brake and tire management. For context, McLaren had been the undisputed leader in tire preservation all season, so for Red Bull to close that gap, and arguably surpass it at Monza, signaled a seismic shift.

What This Means for the Remainder of 2025

The Formula 1 calendar’s final eight races feature a mix of abrasive track surfaces, high ambient temperatures, and diverse challenges—from the heat-soaked streets of Singapore to the night-time spectacle in Las Vegas, and the high-speed, tire-stressing circuits in Mexico and the Circuit of the Americas.

Red Bull’s new brake cooling system will be tested relentlessly across these venues. While it’s premature to declare Verstappen the favorite to snatch the championship, this upgrade means he will be a consistent contender for podiums and race wins, capable of slicing into McLaren’s points haul.

If Verstappen can regularly challenge McLaren’s pace, it could influence the title fight by denying McLaren drivers crucial points, making the championship a tighter contest.

Long-Term Implications Beyond 2025

Another critical dimension is the transferability of this technology to next season. The upcoming 2026 technical regulations introduce significant changes, including new tire sizes, which will require brake systems to be re-engineered.

Red Bull’s experience with this revised brake duct setup this season will give them a valuable head start. The learnings in brake thermal management and tire preservation will feed directly into their 2026 car development, potentially giving them an advantage in adapting to the new regulations.

What About McLaren?

For McLaren, this development means they can no longer rely on a brake cooling advantage to dominate tire management. They will need to continue innovating to maintain their edge against a Red Bull team that has clearly learned and evolved.

Looking Ahead: The Next Battlegrounds

Certain upcoming circuits, particularly Singapore and Mexico, will highlight the efficacy of Red Bull’s upgrade. Singapore’s extreme heat will test the system’s ability to keep tires in the optimal temperature window, while Mexico’s high-speed straights and heavy braking zones will challenge brake cooling and tire preservation.

Conclusion: A New Chapter in the 2025 Title Fight

Red Bull’s discreet but impactful adoption of a McLaren-style brake duct system at Monza has shaken up the status quo. Verstappen’s dominant win showcased the power of this upgrade—not just in pace but in tire management, a crucial factor in today’s F1 racing.

As the season progresses, the battle between McLaren and Red Bull promises to be more intense than ever, with the new brake system playing a pivotal role. Verstappen may not have a realistic shot at the title without multiple misfortunes for McLaren, but his presence as a fierce competitor is guaranteed to influence the championship fight.

For fans and technical enthusiasts alike, the next eight races will provide thrilling insights into how subtle technical innovations can rewrite the competitive landscape in Formula 1.
