Brembo and Mercedes have released a joint statement confirming that they are yet to find the cause of Lewis Hamilton’s brake failure during qualifying for the German Grand Prix last weekend.

During the first stage of qualifying, Hamilton crashed in the final sector with some force after his front-right brake disc failed. The Briton walked away unharmed, but was forced to start the race from 20th on the grid. He eventually rallied to come home in third place, although he did lose more ground to championship rival and teammate Nico Rosberg, the eventual race winner.

In a statement, both Brembo and Mercedes underlined their commitment to resolving the issue despite not finding a reason for his crash yet.

“Following the accident experienced by Lewis Hamilton last Saturday at Hockenheim, Brembo and Mercedes have been working hand in hand to analyse and identify the causes of the failure,” it reads.

“There is currently no clear evidence of a single cause of failure and our continuing rigorous analysis will take into account multiple factors which could have contributed to the incident. The results of this technical analysis will be communicated as soon as they are available.

“Formula 1 is a domain of advanced development where technologies are pushed to their limits and in which strong partnerships are crucially important. Brembo and Mercedes remain committed to a close working relationship in the future.”

Hamilton finished fastest in both of today’s practice sessions for the Hungarian Grand Prix, and is chasing an unprecedented fifth victory at the Hungaroring this weekend.

    The disc blew up from heat failure.

    There was a flaw in the construction of the disc that was not found in the manufacturing process.

    The disc could not process the heat it was supposed to be able to stand and failed.

    The only way this is not a disc construction failure is if a piece of paper or debris got stuck in the brake cooling inlet and stopped the air from going to the surface of the disc.

    Mercedes telemetry would show this as a sudden increase in disc temperature just before it failed.

    Would they admit that was the issue?

    Who knows.

    There are many possibilities. Heat alone is not likely to have been the issue as Mercedes telemetry would have documented this. Both Mercedes and Brembo are trying to figure out the root cause. Seeing as though these disc take about six months to produce and go through all sorts of inspections to eliminate any flaws, the failure is a true mystery at this point in time. Other teams use the same discs without issue so it is puzzling but a concern to all from a safety standpoint.
