Mercedes confirms the cause of Hamilton’s Germany brake failure

1 Comment

Mercedes has finally diagnosed the cause of Lewis Hamilton’s brake failure during qualifying for the German Grand Prix five weeks ago, confirming that the quality of the part itself was not the problem.

The Briton suffered a huge crash during the first part of qualifying at Hockenheim after losing control under braking. At the time, the team deemed it to be a right-front brake disc failure, with the exact cause being unknown. The shunt was severe enough to warrant a visit to the medical centre, where Hamilton was given the all-clear by the circuit doctors.

Mercedes confirmed that it would immediately investigate the issue with brake supplier Brembo, and released a statement in Hungary saying that no definitive cause had yet been defined.

However, the German marque has today confirmed that the issue was caused by the interaction between the structure of the brake material and the brake mounting on Hamilton’s car.

The full statement from Mercedes and Brembo reads:

“Following extensive joint analysis of the previously unseen failure mode experienced by Lewis Hamilton during Q1 at the German Grand Prix, Brembo and Mercedes have reached definitive conclusions concerning the cause of the failure.

“First of all, both parties can now confirm that the quality of the disc material was not a contributory factor. 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.”

The Briton will start today’s Belgian Grand Prix from the front row of the grid behind teammate and championship rival Nico Rosberg.

You can watch the race live on NBCSN and Live Extra from 7.30am ET today.

NHRA: Brittany Force cleared to race this weekend in Phoenix after bad wreck 2 weeks ago

Drag racing is a Force family tradition. So, too, is not keeping a Force family member down.

Just 12 days after the most serious wreck of her six-year drag racing career, Brittany Force and John Force Racing announced late Thursday afternoon that the defending 2017 NHRA Top Fuel champion has been medically cleared and will indeed race in this weekend’s NHRA Arizona Nationals at Wild Horse Pass Motorsports Park in suburban Phoenix, Arizona.

“I flew into Phoenix early this (Thursday) morning and headed straight out to the race track to meet up with my team,” Force said. “I suited up and got belted back into my car that I ran all last season.

“It honestly felt good to be strapped back in and I was surprised how comfortable I was. I’m looking forward to getting back in my car tomorrow (Friday’s first two rounds of qualifying) and getting back in the swing of things with my guys.”

The 31-year-old Force, one of four daughters of 16-time NHRA Funny Car champ John Force, suffered a concussion and bruising after the hard crash she was involved in on February 11 in the first round of eliminations of the season-opening NHRA Lucas Oil Winternationals in Pomona, California.

Shortly after leaving the starting line in a race vs. Terry Haddock, Force’s dragster crossed from the right to left lanes, impacted the retaining wall with a very hard lateral crash, bounced off, spun, went on its side and briefly caught fire after crossing the finish line wheels-up.

While she is still recovering from the bruising, Force feels strong enough to get back behind the wheel. Getting back in the race car could be the best medicine of all, since she has three runner-up finishes in Phoenix, including back-to-back second-place showings in both the 2016 and 2017 national events.

The three-day event kicks off Friday with qualifying rounds at 4 and 6:30 p.m. ET, the same times as Saturday’s qualifying. Final eliminations begin at 1 p.m. ET Sunday.
