Brembo Unveils Use of its Braking Systems at the 2017 Azerbaijan Formula 1 GP

6/21/2017

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

From June 23 to 25, Baku City Circuit will host the first annual Azerbaijan GP for the 8th appointment of the 2017 Formula 1 World Championship. Just one year ago, 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 Nico Rosberg managed to complete a lap going an average speed of more than 210 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 on a scale of 1 to 10, the Baku City Circuit is demanding on the brakes.

The Azeri track earned an 8 on the difficulty index, which is just what nearby Sochi and three other tracks got, including Monza.

 

 

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 seconds every lap, that is seven 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, 17% in Canada. The average peak deceleration, on the other hand, is just 4 G since none of the braking sections reach 4.7-4.8 G like it does on other tracks, and because there are curves with deceleration that doesn't go over 3 G. The unexceptional deceleration is also evident by the amount of energy dissipated in braking by each car over the course of the GP: 171 kWh, which is the same amount of electric energy consumed by 350 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 77.5 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, seven are of medium difficulty and two are light.

The most difficult corner for the braking system is at turn 3: the single-seaters arrive going 319 km/h and in just 2.28 seconds, they take it down to 95 km/h. To do this, the drivers apply a load of 153 kg on the brake pedal and undergo a deceleration of 4.6 G.

Applying the brakes, the cars travel just 64 meters, which is less than length of the gigantic Azerbaijan national flag flying over Bayil. The load on the brake pedal is slightly more at turn 1 (154 kg), but the reduction in speed and the time spent braking are lower: 2.03 seconds to go from 325 km/h to 122 km/h.

As a result there is less braking space, 57 meters. The braking section at turn 15 is also very long: 59 meters and 2.14 seconds, but the drivers are under a little less stress because the deceleration is "just" 4.4 G and the load on the brake lever comes to 143 kg.


 

Brembo performance

The Azerbaijan GP has the potential to 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 25 times by the Italian brakes. Since 1975, the season Brembo brakes debuted in Formula 1, Brembo braking systems have won 370 GP races, 91 of which were with Michael Schumacher.
