Brembo Unveils Use of its Braking Systems at the 2018 Azerbaijan Formula 1 GP

4/23/2018

The brakes are under significant stress on the first corner at the Baku City Circuit

From April 27 to 29, Baku City Circuit will host the second annual Azerbaijan GP for the 4th appointment of the 2018 Formula 1 World Championship. In the 2016, the Baku race was designated the European Grand Prix.


 


The track, designed by architect Hermann Tilke, winds through the picturesque streets of Baku. The endless straightaway (2 km) 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, last year Lewis Hamilton managed to complete a lap going an average speed of more than 214 km/h. 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 20 tracks in the World Championship, the Baku City Circuit is moderately 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 17 seconds every lap, that is 6 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: 17% in Baku, 15% in Canada. The average peak deceleration, on the other hand, is just 4.2 G since none of the braking sections reach 4.9-5 G like it does on other tracks, and because there are curves with deceleration that doesn't go over 3.2 G. The unexceptional deceleration is also evident by the amount of energy dissipated in braking by each car over the course of the GP: 181 kWh, which is the same amount of electric energy consumed by 370 Azeri inhabitants during the race.

From the starting line to the checkered flag, the Brembo technicians forecast that each driver will apply a load of almost 71 tons on the brake pedal, which is 100 times the weight of the SPOT7 satellite managed by the Azerbaijan National Aerospace Agency.

 

 
 

The most demanding braking sections 

Of the eleven braking sections at the Baku City Circuit, two are classified as demanding on the brakes, six 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 315 km/h and in just 2.03 seconds, they take it down to 99 km/h. To do this, the drivers apply a load of 139 kg on the brake pedal and undergo a deceleration of 4.8 G.

Applying the brakes, the cars travel just 56 meters, which is less than length of the gigantic Azerbaijan national flag flying over Bayil. The load on the brake pedal is identic at turn 1, but the reduction in speed and the time spent braking are lower: 1.79 seconds to go from 317 km/h to 126 km/h.

As a result there is less braking space, 50 meters. The braking section at turn 15 is also very long: 51 meters and 1.89 seconds, but the drivers are under a little less stress because the deceleration is "just" 4.6 G and the load on the brake lever comes to 129 kg.


 

Brembo performance

The Azerbaijan GP has become the 35th unique GP race won by a single-seater with Brembo brakes. First place goes to the Monaco GP, which has been won 26 times by the Italian brakes. Since 1975, the season Brembo brakes debuted in Formula 1, Brembo braking systems have won 386 GP races, 91 of which were with Michael Schumacher.
