How have the brakes changed in Formula 1

New rules, new brakes The adoption of new Formula 1 technical regulations starting this season has led, among the most visible innovations even to the naked eye, to the adoption of the new 18-inch rim flanged wheels. The transition from the previous 13-inch wheels brought a number of significant technological challenges Not only for teams and Pirelli, the official tire supplier, but also for those dealing with braking systems. At Monza, over the weekend at the Italian Grand Prix, we were guests of Casa Brembo, where we were able to see what the regulatory change entails from a brake point of view – and experience it firsthand.

What changes from 2021 We have before us the calipers and discs from last and current season, as well as calipers dating back to the 2014 season. The differences are noticeable at first glance, but it’s the details that make everything more exciting. to expose them Matthew CastiBrembo race engineer:The new brakes have a diameter of 328 mm, as specified by the FIA ​​regulations. Compared to 2021, Towing increased with the transition to 18-inch wheels, as well as thickness. On the surface of the disc there are holes with a diameter of 3 mm, which are always determined by regulation and fewer than in 2021, having gone from 1500 to 1000“.The other big news about wheels in 2022 is the introduction, for aerodynamic reasons, of wheel covers. While it presents an added element of the challenge, it actually hasn’t presented significant difficulties for Brembo:”With wheel covers, ventilation is always ensured by air duct, between the vertical stand and the suspension arms, which direct the air flow in the area of ​​u200bu200bthe entry and exit of the disc. It was a tough situation for Brembo, but it didn’t affect much, the discs are well ventilated“.

The difference is in the details In compliance with cost containment, and most importantly with the introduction of a cap on spending for teams, the systems Brembo provides to teams are all the same:Same specs for all teams – Casti showed us – We supply Ferrari, Alpha and Haas cars. The groups are the same and in the race weekend one is used in free practice on Friday, then a new group is put together for FP3, qualifying and racing. Where there can be differences between the difference in the design of the caliperwhich is attached to one seat and inserted according to the ventilationThis last aspect becomes clear when we look in detail at the 2021 and 2022 tongs on the table: One of them has a kind of spikes on the surface, and the other one has wings. Both have a cooling function, and they manage the air flow. These are very tricky fine mechanical processes that give a good idea of ​​how much detail matters in F1.

The role of the difference If the differences between the different single-seat models, and between the 2021 and 2022 specs, are significant, the change from the 2014 caliper, which is also on the table, is even more pronounced. At the time, the pistons were 4 versus current 6. Where there are no differences, it is between circuit and circuit. In this case, the braking system remains the same and it is up to the team to make changes according to the characteristics of the track. Caste concludes:The pads, discs and calipers are the same for all circuits, what changes is the different heat dissipation, which is removed into the air duct and so it’s up to the difference.“.
