Mercedes F1 team reveals Hamilton German GP brake failure findings

Mercedes and brake supplier Brembo have officially ruled out a quality control issue as the cause of the failure on Lewis Hamilton's car in qualifying for July's German Grand Prix.

Hamilton crashed into the barriers in Q1 at Hockenheim due to a right front brake disc failure.

Following detailed analysis that was undertaken after the accident, the team revealed on Sunday that the way the disc interacted with the Mercedes mounting was to blame.

"First of all, both parties can now confirm that the quality of the disc material was not a contributory factor," said a statement issued by the team.

"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."

Mercedes' faith in Brembo materials means the team is once again using the Italian company's discs at the rear of the car at the Belgian GP.
