One of the changes that are a direct consequence of the increase of speed of passage through a curve, weight, and dimensions of the cars, is the thickness of the brake discs, which will go from having 28 mm to 32 up to, but this does not imply that all the teams are going to do, since such an increase will increase the weight of 150 grams per unit.
In any case, the greater downforce and mechanical grip through the wider tires will affect braking and, to understand it better, Mauro Piccoli -Director of sales aerospace and performance Brembo – has given his point of view about it.
According to the Italian, the braking power will increase 25% and the increased thickness will also increase the cooling of the discs, so that its effectiveness also will be strengthened. “The disk more width will allow us to have more holes for cooling, in addition to be able to design a better valve braking. In 2017 there will be more braking power, so you have to redesign the disc in relation to the changes. The grip level will be higher, so basically you will be able to transmit more force in less time in the braking. This causes the braking force to increase to 25% according to the prediction”, said Piccoli in statements to Motorsport.
Another of the aspects that Piccoli accurate is the speed on the approach to the braking. It is obvious that, in general, the speed of arrival will be higher, but due to the many curves which before were not to fund now yes they will, this effect is multiplied even more. “We have seen in the simulations at points where cars slow down a little between curves the car before it slowed down in the first curve, and reduced their speed at the input of the second. But we hope that in some circuits, when the first bend is not too tight, and may be taken with the throttle, in general, the rate of entry into the second will be higher than in 2016″.
Finally, Piccoli addresses the controversial issue of overtaking, as many predict that they will decrease to minimize the braking distance and, therefore, have a smaller margin of difference between riders. “Although some braking distances will be reduced this year, we have yet to see whether overtaking will be like in the past. If you get to a curve without having the car brake on the previous (as in 2016), such a curve will have a greater braking action. So the speed will be much higher than in the past and in the end, the braking distance may be greater than or equal to the power of the brakes”, said the Italian.
