The 2020 Formula 1 Eifel GP according to Brembo

 A guide to the Brembo braking systems on Formula 1 single-seaters, and their use at the Nürburgring

​​​​​​​​​​​​​


According to Brembo technicians, the Nürburgring is one of the most demanding circuits for the brakes. On a difficulty index scale of 1 to 5, it earned a 4, the same as the Sochi track that was the race venue two weeks ago. 


F1 is coming back to this circuit after 7 years away, so it'll be the first time the single-seaters have raced with hybrid power units. The track includes 17 bends (10 to the right) and significant altitude variations: from the lowest point to the highest, there's a difference of more than 23 meters (25 yds) and this can complicate the throttle-off moments, especially if it's raining. ​ ​​


 


Brembo Brake-by-Wire for Formula 1 ​ ​



Since 2014, when Brake-by-Wire was introduced in Formula 1, Brembo has redesigned the rear part of its braking systems to create solutions that allow the brakes and energy recovery systems to coexist in the best possible way. These technologies are making their F1 debut at the Nürburgring. 


Brembo produces various Brake-by-Wire components for the teams: actuators for some, valves and rigidity simulators for others. Continuous research is carried out on the maximum miniaturization of Brake-by-Wire elements. The TTL (time to lock) is 100 milliseconds, three times quicker than traditional solutions. ​

Brake use during the Formula 1 Eifel GP​


The drivers use their brakes on 9 of the bends on the German circuit, meaning that the braking system is called on for a total of 12.2 seconds per lap - the third lowest value of the 2020 World Championship after Monza and the Red Bull Ring. On 4 of the Nürburgring braking sections, the braking system is employed for less than one and a half seconds. 


On the other hand, the drivers are subjected to moments of considerable deceleration: at least 4.3 g on 8 bends and going well over 5 g on a couple of those. From the starting line to the checkered flag, each driver exerts an average overall load of more than 63 tonnes on the brake pedal, double that of the Italian GP in Monza. ​ ​​

 


 

The most demanding braking section of the Nürburgring Round​​


Of the 9 braking sections at the Eifel GP, 3 are classified as very demanding on the brakes, another 3 are of medium difficulty and the remaining 3 are light. 


The most formidable is on the first bend, where the drivers come in at 338 km/h (210 mph) and apply their brakes for 2.32 seconds, during which the vehicle travels the 118 meters (129 yds) that are essential to bring the speed down to 111 km/h (69 mph). The load on the brake pedal is 135 kg (298 lbs), and the deceleration is 5.4 g. ​
