FIA confirms McLaren’s rear brake system is legal after Miami GP inspection. The FIA inspected McLaren's rear brakes after the Miami GP to confirm compliance with regulations.

What Leaked
At the end of each GP, a car undergoes an inspection by the FIA for more in-depth technical checks beyond the routine ones (weight, floor wear, etc.) that are done after the checkered flag.

The Federation informs which car and what was inspected ahead of the following weekend, and most likely, one of the first documents the FIA will release at the Imola GP will be related to the technical checks performed on one of the two McLaren MCL39 cars.

According to The-Race.com, FIA delegates focused their attention on the rear brakes. The brake ducts and drums were inspected to put an end to rivals’ suspicions, particularly from Red Bull, who questioned how McLaren could manage to cool the brakes so effectively using only air. Everything was found to be in compliance with the regulations, so McLaren’s meticulous work on managing rear axle overheating will continue to provide them with a significant advantage, especially as the calendar includes “hot” races. During the Miami weekend, McLaren’s Zak Brown poked fun at Red Bull by drinking from a bottle labeled “water for the tires.” Toto Wolff has no doubts that McLaren is legal and has simply outperformed its rivals.
