Brembo unveils the use of its braking systems at the 2017 Formula 1 Abu Dhabi Grand Prix
The 11 braking points at Abu Dhabi together with the sweltering heat
put the temperature of the #f1 brakes at risk
Yas Marina has two braking sections that last more than 2.5 seconds
The 20th and last race of the Formula 1 World Championship is scheduled for November 24-26 at Yas Marina Circuit in Abu Dhabi. The track is on the man-made island of the same name, next to Ferrari World, in the area north-west of the capital of the United Arab Emirates.
The first part of the track is very fast with two straights where the DRS is used. Then, beginning from turn 11, the number of tight turns increases, keeping the cars from reaching 186 mph on the rest of the track.
The race begins at 5 pm in daylight but when the sun sets half an hour later, the last hour is contested under artificial lighting. This dramatic shift translates into what can be a 27°F drop in temperature, which reduces the grip and results in unstable braking performance.
In the first half hour of #racing under the boiling hot sun, grip is high as is the temperature of the braking system. This can cause thermal discharge problems and wear down the friction material.
According to #brembo technicians, who have classified the 20 tracks in the World Championship on a scale of 1 to 10, Yas Marina Circuit is one of the world's most demanding tracks on the brakes. The Arab track earned a 10 on the difficulty index, the same score given to the circuits in Montreal, Mexico City and Singapore.
The demand on the brakes during the GP
Even though there are 21 corners, the drivers only use their brakes 11 times each lap. Only the city tracks in Singapore and Monaco have more braking points, 15 and 12 respectively. The brakes are used for a total of 18.5 seconds each lap, which equals 17 minutes over the course of the whole race, 19% of the GP.
The average peak deceleration per lap is 3.8 G, but taking into account just the first 11 corners, the average exceeds 4 G, a figure that is not reached on any of the other turns. The energy dissipated during braking in the whole GP from each single-seater is 178 kWh, which is quite similar to the Bahrain GP.
From the starting line to the checkered flag, each driver exerts a total load of 63 metric tons on the brake pedal. On the single lap though, the load exceeds 11 tons.
The most demanding braking sections
Of the 11 braking sections at Yas Marina Circuit, three are classified by #brembo technicians as very demanding on the brakes, five are of medium difficulty and three are light.
Preceded by the almost 0.75-mile long straight, the most challenging braking section is turn 8: The single-seaters arrive at it going 204 mph and then brake for 2.79 seconds to slow to 45 mph. They manage to do this in 80 yards by applying a load of 278 lbs on the brake pedal and undergoing a deceleration of 4.7 G.
Another challenging corner comes after the second sector where the DRS can be activated, turn 11: The drivers need just 71 yards and 2.53 seconds because they arrive going slightly less fast (198 mph) and enter the corner going a bit faster (52 mph). But the load on the brake pedal and the deceleration are identical.
The third most important corner in terms of time and space is turn 14, where the single-seaters go from 176 mph to 56 mph: They need 2.47 seconds and 60 yards, but the intensity of the force on the drivers is lower than at turn 5. This last turn requires a deceleration of 4.7 G and a 278-pound load on the brake pedal, despite a reduction in speed of "just" 104 mph, from 183 mph to 80 mph.
Brembo performance
Single-seaters with #brembo brakes have won six of the last eight Abu Dhabi GP races disputed up to now: Both Red Bull and Mercedes have three victories to their name. The most successful driver is Sebastian Vettel with three wins; none of the Ferrari drivers have ever been able to secure the pole position on this track.
