Brembo Unveils Use of its Braking Systems at the 2017 Italian MotoGP

5/30/2017

The main pitfalls for Viñales, Rossi, Lorenzo, Marquez, Pedrosa and Zarco's brakes

Warmed by the affections of more than 100 thousand fans, Valentino Rossi has a golden opportunity for redemption for his disappointment after the last GP in France: from 2 through 4 June, the Mugello track will host the 6th round of the 2017 MotoGP World Championship season.

Since 1976, the track in the province of Florence has hosted the World Championship GP, but only since 1994 has it been the Italian GP permanent headquarters.

Valentino Rossi has raced there since 1996 and he has taken 9 wins in all the categories, always using Brembo calipers, discs and pads Brembo.

The 5,736 yards of the track that winds its way through the Tuscan hills stand out for their frequent slope changes: if you risk lacking the necessary speed to make it up the uphill turns after braking too much, on the downhill corners you run the opposite risk, namely running long because you have braked too late.


The track also boasts one of the longest straights on the Championship calendar (1,248 yards) that demands a powerful engine and, naturally, a top notch braking system so you won't lose whatever you have gained on the straight in braking.

This explains why 100 percent of the MotoGP riders rely on Brembo systems - a valid choice for all of the 2017 World Championship races.
               


 

 

The 14 remaining turns, on the other hand, are spaced rather evenly along the track, giving the carbon discs time to cool, despite the high temperatures that the asphalt usually reaches. According to Brembo technicians, the Mugello Raceway falls into the category of those tracks with medium difficulty for the brakes.

On a scale of 1 to 5, it earned a 3 on the difficulty index, the same score given to Le Mans (which, however, has much shorter straights) and 7 other tracks.


 
 

The demand on the brakes during the GP

Just like the Qatar GP, the Mugello Raceway also has a braking session at over 217 mph and all the others are lower than 167 mph. In all, the MotoGP riders use their Brembo brakes 10 times per lap, for a total of 28 seconds, which translates into 26 percent of the entire race.

Of all the Grand Prix races held this year, this is the lowest percentage: at Jerez, this value was 33 percent and at Le Mans it was 32 percent. Affected by 6 braking sections where maximum deceleration is at least 1.3 g, average deceleration is 1.15 g, identical to the values at Assen and Brno.

Adding up all of the force a rider applies on the brake lever from the starting line to the checkered flag, the result comes in at more than 1 ton, the fourth lowest in the entire championship.

At Losail, Jerez and Valencia, on the other hand, the total load is 1.4 tons. In any case, during one lap at Mugello, the riders apply a force of almost 92.5 lbs on the brake lever.


 

The most demanding braking sections

Of the 10 braking sections on the Mugello Circuit, only one is classified as demanding on the brakes, whereas 5 are of medium difficulty, and the remaining 4 pose only a light challenge on the braking systems.

The most difficult braking section is the San Donato corner (turn 1): at the end of a downhill section, the MotoGP bikes arrive at 220 mph (a bit faster with the slipstream) and enter the corner at 56 mph. To manage this, the riders brake for 5.2 seconds, during which they travel 315 yards. The deceleration is brutal - 1.5 g and it exceeds the 0.18 g of the Porsche 911 GT3. The load on the lever is 11.9 lbs and the Brembo HTC 64T brake fluid pressure reaches 134.9 psi.

That pressure reaches 137.8 psi on turns 10 (Scarperia) and 12 (Correntaio), which is equal to three times the pressure of a bottle of sparkling wine: in both cases, the bikes arrive at less than 149 mph and brake for less than 4 seconds, but the load on the lever is still 12.1 lbs.

Noteworthy are the 220.9 yards of braking at turn 15 (Bucine) due to its downhill configuration: the MotoGP bikes go from 164.7 mph to 67.1 mph in 4.2 seconds and maximum deceleration touches 1.5 g.

 

 

Brembo performance

Brembo brakes have won the last 24 Italian GP races, including the 1993 edition held at Misano. After all, just two weeks ago Brembo celebrated 22 consecutive years since its last 'non-victory' in the 500-MotoGP championship: an incredible streak, especially considering that, unlike the tires, all the teams can freely choose the braking system that they deem best.

Jorge Lorenzo has won 5 out of the last 6 Italian GP races: will he be able to repeat the performance astride the Ducati?
