Mercedes mechanics found a problem in Kimi Antonelli’s front brake assembly just before the formation lap at the Singapore Grand Prix, then rushed a repair at Marina Bay that had to last the full 62-lap race. Mercedes said the brake scare came from heat soak in the brakes after a sensor issue on the reconnaissance lap.
Antonelli said he felt he had “not brakes” after a Virtual Safety Car pit stop on lap 40, and said that when he went to brake at Turn 7, “nothing happened.” He said Mercedes had brake issues and no reliable brake temperature data, which made the car difficult to control. He managed by lifting and coasting and easing pressure on the pedal.
Antonelli was repeatedly warned over the radio about track limits and recorded four violations, which normally would have brought a five-second penalty. Mercedes challenged one of his laps, and the stewards revoked that lap deletion, leaving him without a sanction. Antonelli recovered enough to finish third after Lando Norris ran deep and he overtook Lewis Hamilton’s Ferrari.
