Lewis Hamilton's German GP qualifying crash to be investigated

Hamilton's hopes of fighting for victory at Hockenheim were wrecked when a right front brake disc failed during qualifying, pitching him off the track and in to the barriers.

The incident prompted Hamilton and team-mate Nico Rosberg to switch to Carbone Industrie discs for the race, only escaping penalties because the FIA accepted the discs were similar in weight, inertia and function.

Brembo is continuing its investigation into the failure - which caused the disc to split in to three - but insists there are no major concerns about its products as the problem appears to be a one-off.

A Brembo spokesman told AUTOSPORT: "We are calm because of the fact that it was a single episode and because we will discover the causes which determined the issue.

"The same material with the same specification has been successfully used this year in more demanding and harder grands prix, such as Canada and Bahrain.

"Each single brake disc is tested on a test bench with stresses and tests in excess of the maximum effort conceivable during the race, so with maximum margins.

"The causes that can have induced the failure are various and even external, and as soon as we have at our disposal all telemetry data we are able to give correct, complete and true information."
