The Formula One 70th Anniversary GP according to Brembo

8/4/2020

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

​​​​​​​​​


​The Formula 1 World Championship is celebrating the 70th anniversary of its debut, which took place on the Silverstone Circuit: at that time, none of the single-seaters were fitted with Brembo brakes, for the simple reason that the Italian company wasn't founded until 1961. Its Formula 1 debut dates back to 1975, with the Ferrari team that conquered the top spot again precisely that year. 


According to Brembo technicians, the Silverstone Circuit falls into the category of those tracks that make little demand on the Formula 1 brakes. On a scale of 1 to 5, it earned a 2 on the difficulty index - less than the 3 assigned for MotoGP (which will not be stopping off there this year however). ​


 


The Brembo calipers for Formula 1​



Brembo makes 6-piston aluminum-lithium calipers (the maximum value established by the regulations) for 8 of the teams in the 2020 World Championship. In addition to these, Brembo also supplies some teams with 4-piston calipers to be used on the rear, to meet the demands for lighter weight. 


Based on the specific vehicle requirements, each team - together with Brembo engineers - identifies the optimum weight-rigidity ratio that the brake calipers must have. The development of the braking system takes place entirely autonomously and separately for each team. ​

Brake use during the Formula One 70th Anniversary GP 


The average of the maximum decelerations on the British track is 3.2 g - slightly higher than Hungaroring - but the values of the single braking situations cover a very wide range: from 1.7 g on bend 13 to 4.9 g on bend 16, with 2.7 g on bend 4. 


Despite staying below, the peaks of the Red Bull Ring, the dissipated energy values on the individual bends isn't even either: it exceeds 1,500 kWh in three cases, but on another three it doesn't even reach 500 kWh. This means there are no areas with at least two consecutive hard braking situations, so the braking system has time to cool down.

 


 

The braking section with the most pronounced deceleration on 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 bend that subjects drivers to the strongest deceleration is number 16: 4.9 g, compared with the 4.8 g of the third bend. The single seaters come in at 294 km/h (183 mph) and slow to 107 km/h (66 mph) in the 2.23 seconds it takes them to travel 107 meters (351 feet), ready to take the bend.​
