The MotoE World Cup 2022 starts on this weekend at the Spanish GP. According to Brembo technicians, the Circuito de Jerez - Angel Nieto falls into the category of highly demanding circuits for the brakes. On a scale of one to six, the Andalusian circuit has a severe index of four.
The Circuito de Jerez - Angel Nieto hosts the first round of the MotoE World Cup at the Spanish GP, scheduled from April 29th to May 1st. According to Brembo, whose technicians assist the MotoGP and MotoE, the Jerez de la Frontera circuit falls into the category of highly demanding circuits on the brakes, with an index of four on a scale where the maximum is six.
The Jerez circuit is 4423m in length with five left-hand and eight right-hand corners and a final straight of 607m. During a full lap the MotoGP bikes use the brakes at practically every corner, with the exception of turn three, for a total of 35 seconds per lap while the MotoE use them for 21 seconds only.
Of the twelve MotoGP braking sections at the Circuito de Jerez - Angel Nieto, two are classified as demanding on the brakes, five are of medium difficulty, while the remaining five have a slight impact on the braking systems. Both for the MotoGP and for the MotoE, Turn 1, Turn 6 and Turn 13 are the three most challenging corners for braking.
The most hard braking for the MotoGP and MotoE in Jerez is at corner sixth: at the end of the straight line of 0,6 km, the MotoGP riders reach 300 km/h before braking for 5,4 seconds during which they are subjected to 1,5 g of deceleration. The MotoGP bikes enter turn 6 at 68 km/h after braking for 238 meters, performing a maximum load of 5,9 kg on the brake lever.
The MotoE starts braking at 224,5 km/h and slows down to a speed of 66,5 km/h; it covers 180 meters in 4,7 seconds. In practice, the braking time is longer for MotoGP than for MotoE but what changes is the maximum deceleration which for the MotoGP reaches the value of 1,5 g while the MotoE reaches a maximum of 1,2 g.
The Brembo braking system for the MotoE

The discs are of the "T-Drive" type in steel while the calipers are the GP4-PR; let's see the details. The front discs are the steel "T-Drive", have a diameter of 336 mm and a thickness of 7,1 mm with a configuration specifically designed for MotoE.
The front caliper is machined from solid aluminum monobloc, model GP4-PR. It is the caliper already used in the MotoGP championship with steel discs up to the 2017 season, when discs of this type were used in the case of wet races. It has 4 titanium pistons with differentiated diameters of 32-36 mm and is operated by a radial pump with a diameter of 19 mm and a displacement of 18 mm.
