THERE'S A BIG DIFFERENCE BETWEEN 100 MINUTES AND 24 HOURS
Formula 1 races last about 100 minutes, they never go over 2 hours. The 24 Hours of Le Mans lasts an entire day. So, it is better to compare two tracks that are similar in length, number of corners, geographic position and climate.
During the Belgian GP in Spa, the Formula 1 single-seaters have to face about 350 braking sections, while at the 24 Hours of Le Mans, an LMP1 will brake more than 4,000 times.
This is a huge challenge for Brembo. Fortunately, the Company has garnered 20 years of experience in endurance racing and has developed tailor-made solutions.
The only common factor these cars share is that their discs are made of carbon.
What is different, and by a lot, are the disc properties. We've outlined these in the table below:
|Formula 1||24 Hours of Le Manss|
|Disc thickness||up to 32 mm||30-32 mm|
|Front disc diameter||278 mm||up to 380 mm|
|Rear disc diameter||260 - 272 mm||up to 355 mm|
|Number of ventilation holes||Over 1400||Between 36 and 430|
|Range of use ||662-1832°F||662-1472°F|
|Wear per event||less than 1 mm||3-4 mm per disc and 8-10 mm per pad|
The difference in the disc diameter is linked to the size of the rims used in the respective championship races. Currently in Formula 1, 13" rims are allowed. At the 24 Hours of Le Mans the cars are equipped with 18" rims.
