The Crucial Pivot in Ferrari’s 2025 F1 Season: How a Brake Pad Upgrade Transformed Lewis Hamilton’s Performance

At 314 km per hour, with the trees of the Arden Forest flashing by and the track plunging downhill into the fearsome breaking zone of Lelay Comb, the voice of Lewis Hamilton crackled across the Ferrari radio. “That’s better. Much better.” To the casual viewer, it may have sounded like just another mid-race comment. But for Ferrari engineers, it was the sound of months of frustration beginning to lift. That moment, lap 19 of the 2025 Belgian Grand Prix, was more than just a clean entry into a high-speed chicane. It marked a breakthrough, a pivotal moment in a season that had seen Hamilton battling both the car and the adaptation process since his move to Ferrari.

This wasn’t about a new floor or rear wing upgrade—this was something far more subtle. It was a revised Brembo brake pad compound, a thin piece of material, no thicker than a deck of cards. And yet, it was a game-changer. For a seven-time world champion like Hamilton, whose expertise lies in the minute adjustments made under braking, the feel of the brake pedal is crucial. The way he modulates pedal pressure, manages tire slip, and uses weight transfer to rotate the car is what allows him to extract the maximum performance. For the first 12 races of the 2025 season, that feel had been noticeably absent. But at Spa, for the first time that year, Hamilton wasn’t fighting the brake pedal. Instead, he was working with it.

The Evolution of Hamilton’s Ferrari Journey

Hamilton’s first season with Ferrari had been marked by adaptation and frustration. The Super Formula 25, Ferrari’s latest creation, was not built with Hamilton’s input in mind. It inherited the developmental DNA of Charles Leclerc, Ferrari’s in-house driver, who has a more aggressive braking style and prefers a sharper front-end bite. In contrast, Hamilton’s style relies on finesse rather than brute force, requiring a more nuanced and predictable braking feel. In the early races of the season, Hamilton expressed dissatisfaction with the car’s braking system, describing it as vague and unsettling. Behind the scenes, Ferrari’s engineers, including Loic Serre and Enrico Cardiel, had been tirelessly working on understanding and solving the disconnect between Hamilton and the car. The challenge was more complex than simply adjusting suspension geometry; it required an entirely new approach to brake modulation.

The breakthrough came in the form of a revised Brembo brake pad. While the compound was already available to all customer teams, Ferrari recognized its significance at precisely the right moment. The team realized that the feedback Hamilton required under braking was not about raw performance but about consistency and feel. The new brake pads provided smoother thermal responses and a more linear pressure curve, which gave Hamilton the precise feedback loop he craved. It wasn’t a dramatic change, but it was enough to help Hamilton trust the rear end of the car under heavy deceleration, a trust he had been missing for much of the season. In Belgium, Hamilton’s relationship with the car finally seemed to align, allowing him to extract more from the Super Formula 25’s braking zones without fear of unpredictability.

The Technical Significance of the Brake Pad Upgrade

From a technical perspective, the revised Brembo brake pad wasn’t a revolutionary piece of equipment. What made it significant was its modulation gradient, the way the braking torque builds relative to the driver’s foot input. In the Super Formula 25, the brake pedal response had been too aggressive for Hamilton’s taste, especially in high-speed braking zones where precision is critical. The new compound provided more elasticity in the pedal response, allowing Hamilton to brake deeper into corners without sacrificing stability. This adjustment wasn’t about braking later or harder, but about braking smarter—especially in corners like Lource and the Bus Stop chicane, where subtle inputs define the racing line.

Ferrari’s engineering team had already made several modifications to the car’s suspension and hybrid systems, including a revised rear suspension architecture with a lower wishbone to help stabilize the platform under braking. However, it was the brake pad change that made all these improvements come together, providing Hamilton with a more consistent and predictable braking feel. By the time they arrived in Belgium, Hamilton could finally trust the rear end of the car, leading to better modulation of brake pressure and a reduction in unpredictable behavior under heavy braking.

A Strategic Shift: Tailoring the Car to Hamilton’s Needs

The introduction of the new brake pad was not just a technical upgrade—it marked a fundamental shift in Ferrari’s approach to their star driver. Instead of continuing to ask Hamilton to adapt to a car built around Leclerc’s preferences, Ferrari was now willing to customize the car to suit Hamilton’s unique style. This marked the first visible sign of Ferrari prioritizing Hamilton’s needs in the development process, a significant philosophical shift in the team’s mindset. While Leclerc’s preferences had been the cornerstone of the Super Formula 25’s early development, the decision to tailor the car to Hamilton’s inputs signaled a more flexible and driver-focused approach.

This wasn’t just about performance on the track. By aligning the car more closely with Hamilton’s style, Ferrari also improved their strategic flexibility. With improved braking performance, Hamilton was able to preserve tires more effectively, opening up new strategic opportunities such as longer stints and undercuts. Although Hamilton’s race result in Belgium did not reflect a podium finish, the data showed that the upgrade had expanded Ferrari’s strategic options, giving them greater flexibility in responding to race conditions and rival strategies. For a team like Ferrari, which prides itself on racecraft and strategy, this shift was as important as any aerodynamic update.

The Bigger Picture: Confidence, Adaptation, and Championship Implications

While the brake pad change in Belgium may seem like a small adjustment, its impact was felt far beyond just the 2025 Belgian Grand Prix. For Hamilton, the newfound confidence in the braking system was not just about feeling better in the car—it was about regaining his rhythm. Formula 1 is a sport of marginal gains, and in a season where the competition is tighter than ever, small changes can have big implications. Hamilton’s improvement in Belgium wasn’t just about lap times; it was about consistency, and in Formula 1, consistency is often what makes or breaks a championship campaign.

Hamilton’s confidence under braking directly impacts his ability to manage tire degradation, execute overtakes, and make strategic decisions in the heat of the race. As the season enters its final third, with races at circuits like Hungary, Singapore, and Suzuka on the horizon, the benefits of the revised brake pad could be amplified. If Hamilton continues to improve with this new setup, Ferrari could find themselves in a unique position, with both of their drivers performing at a high level. With Leclerc’s more aggressive driving style and Hamilton’s precision, Ferrari now has the flexibility to split strategies and attack their rivals on multiple fronts.

The decision to build the car around Hamilton’s feedback rather than forcing him to adapt could have a lasting effect on the team’s development strategy, especially as they look toward the 2026 regulation cycle. As Formula 1 moves toward a new era of hybrid power units and active aerodynamics, the teams that succeed will be the ones that can create stable, adaptable platforms for their drivers. By understanding the intricate relationship between driver inputs, car behavior, and race strategy, Ferrari is positioning itself to be a force to reckon with in the years to come.

Conclusion: A Quiet Revolution in Ferrari’s Approach

In the world of Formula 1, the smallest adjustments can have monumental effects. Hamilton’s breakthrough at Spa may have been triggered by a simple brake pad upgrade, but its implications are far-reaching. For Ferrari, it marks a subtle yet significant shift in their approach to car development—one that puts driver feedback at the center of their strategy. As Hamilton continues to adapt to the Super Formula 25, and as Ferrari tailors the car to his needs, the team is laying the foundation for future success. In the hyper-competitive world of Formula 1, the ability to adapt to your drivers is just as important as adapting to the ever-evolving technical landscape. Ferrari’s decision to build the car around Hamilton’s instincts could very well be the key to unlocking their true potential in the final stretch of the 2025 season and beyond.
