Mercedes reveals Hockenheim brake findings
24 August 2014 – Mercedes and brake supplier Brembo say the "interaction between the brake material and braking mounting on the F1 W05" caused Lewis Hamilton's qualifying crash at last month's German Grand Prix.
Hamilton hit the barriers in the opening Q1 phase at Hockenheim after suffering a front-right brake disc failure.
The joint statement, issued on the morning of the Belgian Grand Prix, ruled out a quality control issue.
"First of all, both parties can now confirm that the quality of the disc material was not a contributory factor," it read.
"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."
