Lewis Hamilton faced a nervous wait ahead of the United States Grand Prix as Mercedes engineers made last-minute changes to his W13.
The Brit reported to his team that he could feel a problem with his brakes on the lap to the grid around half-an-hour before lights out. To resolve it, the Silver Arrows took the bold decision to completely chance the materials in his brakes with just 15 minutes to go.
Fortunately for Hamilton, his engineers were able to complete the job in time for the formation lap. As the work was carried out under the watchful eye of the FIA technical delegate Jo Bauer, it meant there was no penalty and the start of his race was unaffected by the last-minute work on his car.
