The most demanding braking sections
Of the 11 braking sections at the Circuit de Monaco, only two are classified as demanding on the brakes, two are of medium difficulty and seven are light.
The most difficult braking section is after the tunnel (turn 10): the single-seaters arrive going 297 km/h (185 mph) and brake for less than 2 and a half seconds (2.48 seconds to be precise) to decelerate to 89 km/h (55 mph): they manage to do so in just 118 meters (387 feet). At this point, the drivers undergo a deceleration of 4.5 G and have to apply a load of 144 kg (317 lbs) on the brake lever.
At Mirabeau (turn 5) on the other hand, the speed drops down from 232 km/h (144 mph) to 75 km/h (47 mph), but the single-seaters brake for 2.52 seconds and travel 91 meters (299 feet). The load on the pedal (116 kg, 256 lbs) and the deceleration (3.6 G) are lower though.
The maximum speed over all (298 km/h, 185 mph) is reached after the straightaway at the starting line, S.te Devote: the corner isn't very sharp so the cars can take it at 108 km/h (67 mph), braking for just 2.12 seconds.
