High performance brake supplier Brembo has issued a press release explaining the reason for Sebastian Vettel’s retirement during the Australian Grand Prix in Melbourne last Sunday.

The Italian company first indicated that the cause of the problem was not the braking system of the Red Bull Racing car.

“With regard to the retirement of the Red Bull Racing’s driver Sebastian Vettel during the Grand Prix of Australia, Brembo communicates that the cause of his exit in Turn 13 was not caused by the braking system supplied by Brembo, as some publications have reported.

“Red Bull Racing has confirmed that Sebastian Vettel retired from the Australian Grand Prix after the torque drive between the front left axle and wheel was lost.

“Post race investigations revealed the wheel nut was correctly tightened at the pit stop as well as other possible causes of the fault.

The team has communicated that it's studying a number of solutions at present, which can be implemented for the Malaysian Grand Prix.”
