24h Le Mans
Five years after setting out on its Le Mans adventure, Brembo reached a major milestone in 1989 with its first outright win. Jochen Mass, Manuel Reuter and Stanley Dickens ushered the Sauber-Mercedes home ahead of the field, bringing worldwide recognition to Brembo. This victory marked the beginning of a lasting partnership between the Italian brake supplier and the French endurance classic.
Since the inaugural 24 Hours of Le Mans in 1923, braking technology has evolved continuously. A major turning point emerged with the introduction of carbon discs, now used in the Hypercar and LMP2 classes. These materials, already used in Formula One, were specially adapted to the constraints of endurance, notably to withstand race distances in excess of 4,000 km.
Brake-by-wire systems were introduced for the Centenary race in 2023. With this revolutionary technology, braking pressure is controlled electronically through a solution integrated into the hybrid systems of modern prototypes. Brembo has thus progressed from its role purely as a brake supplier to become a key player in the field of mechatronics.
The Circuit des 24 Heures du Mans is a challenging track for braking systems. Temperature control and wear and tear of the carbon discs and pads are the main issues faced. Overheating calipers or discs can compromise performance – or even driver safety.
The task is further complicated by the rise in hybrid technology. Regenerative braking, used to recharge the batteries on decelerating, reduces stress on the mechanical brakes which must nonetheless remain fully efficient in the event of a hybrid system failure. The components must therefore be capable of absorbing extreme pressure levels in all situations.
The know-how honed by Brembo at the 24 Hours of Le Mans is making its way into everyday motorcars. Endurance encourages the development of low-wear materials and more durable, environmentally friendly components. For instance, Brembo has designed cleaner, more resistant “green” disc brakes based on research conducted on the racetrack.
The future-facing company is also working on a new generation of calipers capable of reducing residual braking torque. This innovation would avoid unnecessary friction when the brakes are not applied, thereby cutting fuel consumption. This promising breakthrough could also reduce the number of pit stops and enhance the overall performance of endurance racing cars.
Over the last four decades, Brembo has undoubtedly established itself as a prime innovator in braking technology at the 24 Hours of Le Mans, making vital contributions to prototype safety, performance and sustainability.
