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.
Grip increases as rubber is laid on the track, and, as we expect the single-seaters to experience in 2018, this will lead the braking torque to be higher compared to the 2017 season.
To deal with the changes adopted this season, Brembo has increased the thickness of the carbon discs from 28 mm to 32 mm, and has added holes to cool them, taking the total from 1,200 to 1,400.
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 20 tracks in the World Championship, Circuit Gilles-Villeneuve falls into the category of highly demanding circuits for the brakes.
