The Japanese GP circuit is one of the least stressful for braking, value 1 on a scale of 1 to 5 according to Brembo, but very technical in terms of shape and variety of its curves: let’s see its characteristics
There’s really no time to catch your breath. After Singapore, where Ferrari celebrated its first victory of the season, F1 flies to Suzuka for the Japanese GP. In a circuit where, according to Brembo, the brakes are used for 14% of the lap time: on a scale of 1 to 5, in fact, the track has a difficulty index of 1, equaled only by Silverstone. But watch out for the weather, as the track is very often subjected to very heavy rain. Like last year, when only 28 of the 53 laps were held due to the long interruption due to bad weather and the three-hour limit being reached.
slope and ‘eight’
Beyond the use of the braking system, the Suzuka circuit, 5807 meters long and 53 laps to be covered, will need to be kept an eye on for its slopes and “eight” shape, which makes it the only track of the World Championship with an underpass (between turns 9 and 10) and an overpass. In each lap, the drivers use the brakes in 12 corners: in three of these the cars lose a maximum of 15 km/h, while in three others the difference between initial and final speed does not reach 70 km/h. Consequently, in all these six decelerations the brakes are operational for less than 8 tenths of a second.
Of Suzuka’s 12 total braking sections, only two are considered demanding on the brakes, three medium and seven easy. The hardest braking of all is at turn 16, the chicane before the finish line, where the single-seaters drop in speed from 304 km/h to 96 km/h in just 105 metres. During the 2.29 seconds of brake operation, riders exert a pedal load of 144kg and are subject to a maximum deceleration of 4.8G. Also pay attention to Turn 11, ‘Hairpin’, where it goes from 260 to 74 km/h in 95 meters, with 4.1 G of deceleration and 2.43 seconds of braking.
