Mercedes and brake supplier Brembo have taken the step of issuing a joint statement regarding the part failure that sent Lewis Hamilton into the Hockenheim tyre barrier during qualifying at the German Grand Prix.

The problem, which was attributed to the front right brake, cost Hamilton a chance of competing for pole position. Having already posted the fastest time of Q1, Hamilton crashed heavily in the closing moments of the phase, allowing Mercedes team-mate Nico Rosberg a free ride to top spot on the grid, while the Briton wound up 20th after penalties were applied before the race.

Analysis of potential causes of the failure began almost immediately, and has been ongoing in the week between the German and Hungarian grands prix.

"Following the accident experienced by Lewis Hamilton last Saturday at Hockenheim, Brembo and Mercedes AMG Petronas F1 Team have been working hand in hand to analyse and identify the causes of the failure, the official statement confirmed.

"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 One is a domain of advanced development where technologies are pushed to their limits and in which strong partnerships are crucially important.

"Brembo and Mercedes AMG Petronas F1 Team remain committed to a close working relationship in the future."

Ironically, Hamilton's brakes appeared to be the subject of scrutiny late in FP2 at the Hungaroring, with an exchange of radio comments suggesting that there may have been a problem on the #44 Mercedes. Hamilton completed the session, however, and set the pace in both Friday practices, ahead of Rosberg.
