某方面来说算是新技术的体现吧，要在寿命跟散热效果做取舍
而墨西哥使用的Brembo刹车碟有七个不同的rows 用以达到1400个散热孔这种神奇的数字
Ferrari first to run ground-breaking 1400-hole brake disc
https://www.motorsport.com/f1/news/ferrari-1400-hole-brake-disc/3205152/
Ferrari became the first Formula 1 team to run a new generation of brake
discs at the Mexican Grand Prix, featuring an unprecedented 1400 holes to
help cooling.
The unique high-altitude demands of Mexico, where teams struggle to keep
temperatures of engines and brakes under control, was the perfect proving
ground for the new disc that will be made available to all customers in 2019.
F1's brake suppliers have long balanced out increasing the number of holes to
help cooling with the need for structural integrity of the disc itself.
Twenty years ago there were less than 30 big holes around the centre of the
disc, and this number only increased dramatically around five years ago when
drilling more than 100 holes was possible.
Advances in technology have moved fast, however, and by two years ago Brembo
had got up to 1200 – believing that to be a limit.
At the time Brembo's Andrea Algeri, F1 and open wheels customer manager, told
Motorsport.com: "The cooling patterns proposed sometimes are quite good –
but they don't take into account the resistance of the disc and the wear.
"The teams want a lot of holes but then want to have only 0.5 mm of wear
possible. This kind of disc would be used for good results just in FP1, and
then you would have to change it. So it is a just a compromise on the life of
the disc that you can reach."
Progress has been possible, however, with the Brembo brake disc used in
Mexico featuring seven distinct rows to reach the magical 1400 number.
