The 2019 Formula 1 Azerbaijan GP according to Brembo


 An in-depth look at the braking systems on the Formula 1 single-seaters at the Baku City Circuit


From April 26 to 28, Baku City Circuit will host the third Azerbaijan GP which represents the 4th round of the 2019 Formula 1 World Championship. In the 2016, the Baku race was called the European Grand Prix.​​


The track, designed by architect Hermann Tilke, winds through the picturesque streets of Baku. The endless straightaway (2 km or 1.2 miles) that leads back to the start permits the cars to reach very fast speeds.​​

In general, the entire track is run with the pedal to the floor, which is demonstrated by the fact that the wide open throttle time is equivalent to 56% of the race. In fact, in 2017 Lewis Hamilton managed to complete a lap going an average speed of more than 214 km/h (133 mph).​

The circuit also has a lot of technical corners, like turns 8 and 15, where precision braking is key to avoiding contact with the walls, which are extremely close at these points.

​The layout includes four 90° corners at the start that demand great effort on the part of the brakes, followed by other turns where the angels change continuously and as a consequence so does the use of brakes.


According to Brembo technicians, who classified the 21 tracks in the World Championship, the Baku City Circuit is highly demanding on the brakes. ​             



The demand on the brakes during the GP

The 11 braking points each lap and the extreme length of the track (more than 6 km) require the drivers to use their brakes for almost 19 and a half seconds every lap, that is almost 7 seconds more than on Circuit Gilles-Villeneuve in Montreal, one of the most challenging tracks for the brakes.

Actually though, the percentage of braking on the overall duration of the race is fairly similar: 19% in Baku, 18% in Canada. The average peak deceleration, on the other hand, is just 3.7 G since only one of the braking sections reach 4.8 G like, and because there are two curves with deceleration that don't go over 1.7 G.


The amount of energy dissipated in braking by each car over the course of the GP is 249 kWh, the fourth highest value of the championship.
From the starting line to the checkered flag, the Brembo technicians forecast that each driver will apply a load of 53 tons on the brake pedal.



The most demanding braking sections 

Of the eleven braking sections at the Baku City Circuit, four are classified as demanding on the brakes, four are of medium difficulty and three are light.​

The most difficult corner for the braking system is at turn 3: the single-seaters arrive going 320 km/h (199 mph) and in just 2.31 seconds, they take it down to 99 km/h (62 mph). To do this, the drivers apply a load of 141 kg (311 lbs) on the brake pedal and undergo a deceleration of 4.7 G. Applying the brakes, the cars travel just 115 meters (377 feet​).


The load on the brake pedal is lower at turn 1 (131 kg, 289 lbs), but the deceleration is much higher: 5.5 G despite the reduction in speed and the time spent braking are lower: 1.84 seconds to go from 330 km/h (205 mph) to 124 km/h (77 mph). As a result there is less braking space, 106 meters (348 feet). ​


The braking section at turn 15 is the longest of all: 125 meters (410 feet) and 2.67 seconds, and the drivers are under high stress: the deceleration is 4.7 G and the load on the brake lever comes to 161 kg (355 lbs).


Brembo performance

The Azerbaijan GP has become the 35th unique GP race won by a single-seater with Brembo brakes. The Monaco GP holds the record having been won 26 times by the Italian brakes. Since 1975, the season Brembo brakes debuted in Formula 1, Brembo braking systems have won 407 GP, 91 of which were with Michael Schumacher.
