The Brembo preview of the 2022 F1 Bahrain GP follows
The Formula 1 World Championship restarts from Bahrain with brand new single-seaters, new tires and ad hoc braking systems. According to Brembo technicians, the Bahrain International Circuit falls into the category of highly demanding circuits for the brakes. On a scale of 1 to 5 it earned a difficulty index of 4, the same value as historic tracks such as Monza and Spa-Francorchamps, albeit with very different characteristics from the latter.
The Bahrain GP will be a testing ground for all these innovations, thanks to a usually very abrasive asphalt, which is cleaned from the sand lap after lap and on which the wind often plays a decisive role. The race will also start after sunset and therefore will be held under artificial lights: this year, however, the presence of the lenticular wheel covers, also unpublished, will prevent you from enjoying the glow of the carbon discs when braking at the end of the straights.

The sizes of the discs and their holes change
The increase in the diameter of the rims, from 13 inches (33 cm) to 18 inches (46 cm), offers more space inside the wheel corner for the carbon discs and thus their diameter goes from 278 mm to 328 mm for the front and from 266 mm to 280 mm for the rear.
The thickness of the discs is now identical for both axles, 32 mm, while until last year the rear discs did not exceed 28 mm. But also the architecture of the discs has changed because the new technical regulation requires a minimum diameter of 3 mm for the ventilation holes while in the past Brembo went up to 2.5 mm.Bound
Four tough braking
In each lap the F1 drivers use the brakes 8 times for a total of 16 and a half seconds, even if a good part of this time is spent in the 4 hardest braking sessions which on average require the braking system to work for just under 2 , 9 seconds. In 3 curves, on the other hand, braking is less than a second and a half and the braking distance is 90 meters.
The tortuosity of the Bahrain International Circuit is evident from the presence of a single point where the speed is well above 300 km / h. Nevertheless, there are 6 curves in which the maximum deceleration is at least 4 g, with a peak of 4.6 g at the first corner.Bound
Only 131 meters to lose 248 km / h
Of the 8 braking sections of the Bahrain GP, 3 are considered highly demanding on the brakes, 4 are of medium difficulty and the remainder is light.
The hardest for the braking system is the first corner because the cars benefit from a straight of 1.1 km: the single-seaters rely on the brakes at 328 km / h and go down to 80 km / h in just 131 meters. To do this, the drivers brake for 2.95 seconds and face a deceleration of 4.6 g. Bound
And in video games?
A few tricks are enough to tackle Turn 1 of the Bahrain International Circuit in the Formula 1 video game: braking must be started with straight wheels when the section where you can use the DRS runs out, referring to the 100-meter sign. The pressure on the pedal must be progressively reduced and then moved to the right, but without touching the curb to avoid being unbalanced and thus losing power.
