Mercedes and Brembo have announced the results of an investigation into the brake disc failure that afflicted Lewis Hamilton in qualifying at the German GP.
They concluded that the disc was not at fault, and instead changes have been made to the car itself.
In a joint statement the two parties said: “First of all, both parties can now confirm that the quality of the disc material was not a contributory factor. Instead, extensive analysis and experimentation has demonstrated that the specific interaction between the structure of the brake material in question and the brake mounting on the F1 W05 Hybrid was at the root of the failure.
“Countermeasures have already been applied to both the disc geometry and the mounting to ensure there can be no repeat of the failure. These developments allow the team to once again run Brembo brake disc material, should it choose to do so, in race conditions.”
