Montreal is without a shadow of a doubt the most demanding test bench for the single-seater braking systems. It is a “stop and go” type circuit characterized by sudden braking sections and acceleration. The braking sections, all hard and very close together, determine an extremely high operating temperature for the discs and pads, which do not have time to cool sufficiently in the short straight stretches. These characteristics, combined with a significantly high percentage of time spent on the brakes, determine a very hard mix for the braking systems, also due to the fact that the aerodynamic load (in other words, the resistance to forward progress) is not one of the highest. The scenario can get even worse when there is a tail wind on the two main straight stretches which can significantly increase the straight line speed, putting the brakes to an even more severe test. A critical point is the chicane before the famous “wall of champions” where control going into the turn is fundamental to avoid hopping the curb. On this turn an excellent feeling with the brakes can make the difference between a good time and retiring with a crash.
All teams equipped with Brembo will use the improved CER 300 disc material, while Brembo continues its research in this field to produce composite materials that continue to offer more performance and controllability. Teams will also use the new ventilated CCR 700 brake pads. During the season, Brembo supplies on average 10 sets of calipers, 140-240 discs and 280-480 brake pads to each two-car teams.
