The Formula 1 British Grand Prix 2020 according to Brembo

 A guide to the Brembo braking systems in Formula 1 single-seaters, and their use on the Silverstone Circuit

​​​​​​​​​​​​


According to Brembo technicians, the Silverstone Circuit falls into the category of those tracks that make little demand on the brakes. On a scale of 1 to 5, it earned a 2 on the difficulty index - lower than all the other tracks in the current Formula 1 World Championship schedule. 


At 52° north latitude, the British track is the closest of any in the championship to the North Pole. This factor, together with the low energy at play, can cause the glazing of the friction material if it rains or if temperatures fall suddenly. ​


 


For the brakes, power isn't always a byword for effectiveness​



The use of the most powerful Brembo Formula 1 braking systems doesn't always produce positive results, because in certain environmental conditions the system might be oversized for the single-seater: an unbridled braking force would make it hard to reach the minimum working temperature. 


At excessively low operating temperatures, the carbon used to make the F1 discs and pads doesn't guarantee correct friction generation and risks becoming glazed, compromising braking performance. Furthermore, the mechanical action of the pads on cold discs can lead to higher wear. ​

Brake use during the Formula 1 British Grand Prix​ 

​​


The British track has 7 braking points, giving a total brake usage time of 12.6 seconds per lap (more than 5 seconds less than Hungaroring). From the start to the checkered flag, the brakes are used for just under 11 minutes. 


Overall, each driver exerts a total load of 30 tonnes on the brake pedal during the race: at the Red Bull Ring it's 39 tonnes, and at Hungaroring 56 tonnes. The reason is that there are only 3 braking situations per lap where the load on the pedal is more ​than 55 kg (121 lbs).

 


 

The most demanding braking section of the Silverstone Round​ ​


Of the seven braking sections at the British GP, two are classified as very demanding on the brakes, one is of medium difficulty and the other four are light. 


The hardest is the one on bend 3, because the drivers come into it accelerating since the start line, without having had to use the brakes on bends 1 and 2, so they arrive at 320 km/h (199 mph); they then drop to 125 km/h (78 mph) in just 2.37 seconds thanks to a load of 150 kg (331 lbs) on the brake pedal, with a deceleration of 4.8 g.​
