Characterized by alternating straightaways, chicanes and hairpin turns, this track is without a doubt the toughest test bench for the braking systems on the single-seaters, which usually show up here with a low aerodynamic load.
The braking points, all hard and very close together, cause soaring operating temperatures of the discs and pads, which don't have enough time to cool down on the straight stretches.
Another problem for the braking systems is the tailwind on the two main straightaways: when it pushes from behind, the straight line speed is increased, putting the brakes to an even more rigorous test.
According to Brembo technicians, who classified the 21 tracks in the World Championship, Circuit Gilles-Villeneuve falls into the category of highly demanding circuits for the brakes. On a scale of 1 to 5, it earned a 5 on the difficulty index, a value also obtained by Singapore, Mexico City and Yas Marina tracks.
