Filed the summer break, MotoGP starts again from Great Britain, the scene of celebrations for the 75th anniversary of the World Championship. At the Silverstone Circuit, all the premier class teams will present themselves with liveries inspired by the past, but the public will also be able to admire a display of the braking components that have made the history of motorcycle racing, of course branded Brembo, a protagonist in the 500 class since way back in 1978. According to Brembo engineers who work closely with all MotoGP riders, the 5.9-kilometer-long Silverstone Circuit falls into the category of moderately demanding circuits for brakes. On a scale of 1 to 6 it has a difficulty index of 3 having 11 braking, including 4 in the Hard category. The brakes are working for 33 seconds per lap, and in the entire GP each driver exerts a total load on the brake lever of 7.8 quintals.
The British GP is often affected by bad weather: in 2018, the race was not held because heavy rainfall made the Silverstone track impassable, despite the fact that many fans stayed in the stands hoping for an improvement in the weather. Until a decade ago, with heavy rain, MotoGP riders opted for steel brake discs, which were considered more reliable on those occasions than carbon. Since 2017, however, more and more riders have been employing carbon discs even in prohibitive conditions, thanks in part to covers made of the same material that keep the discs at temperature in rainy weather and reach the necessary range more easily. Carbon is lighter than steel and therefore does not worsen the dynamic behavior of the bike, plus it ensures better performance both on individual braking and for the entire duration of the race.
The hardest corner on the Silverstone Circuit for the braking system is 15: the MotoGP bikes go from 323 km/h to 123 km/h in 4.3 seconds in which they travel 249 meters while the riders exert a load on the brake lever of 4.8 kg. Deceleration is 1.5 g, Brembo brake fluid pressure touches 10.3 bar and the temperature of the carbon discs reaches 680 °C.
