The most challenging braking sections
Of the nine braking sections on the Autódromo Hermanos Rodríguez, 2 are classified by the Brembo technicians as challenging, 3 are of medium difficulty and 4 are light.
The most demanding over all is on the first corner after the finish because the single-seaters go from 345 km/h to 111 km/h in barely 140 meters. To perform like this, the drivers apply a load of 102 kg on the brake pedal for a total of 2,84 seconds during which they experience a deceleration of 4,2 G.
On turn 4, which also follows a straight where the drivers can use the DRS, they need 3,03 seconds to get outside the racing line. The cars arrive going 331 km/h and slow down to 98 km/h by applying a load of 101 kg on the brake pedal. But only 2,01 seconds and 105 meters are needed to go uphill on turn 12 and reduce the speed from 311 km/h to 141 km/h. The 4,1 G in deceleration proves that the braking here shouldn't be underrated, just like the 101 kg load on the brake pedal.
On the stretch between turns 5 and 10 though, the drivers use their brakes only three times and never for more than 53 meters. But none of these three braking sections require a drop in speed measuring more than 80 km/h.
