Video: Lewis Hamilton winded after heavy crash in qualifiying for German Grand Prix
Lewis Hamilton's wretched run in qualifying continued at the German Grand Prix as an apparent brake failure sent the Formula One title contender crashing out in the opening session at Hockenheim.
Working his way through the stadium complex, and poised to set the quickest time with just over seven minutes remaining, Hamilton was suddenly sent pirouetting off track and into a tyre barrier.
Replays showed a puff of black smoke shoot out from the front-right brake on Hamilton's Mercedes on his approach into a left-handed loop.
After taking a few moments to compose himself before emerging from the cockpit of his wrecked car, Hamilton said over the team radio: "I put my foot on the pedal and something failed."
Hamilton eventually clambered from the cockpit of his car, raising his right hand to acknowledge he was okay.
Race director Charlie Whiting immediately red-flagged the session, with Hamilton's time from his initial hot lap at least good enough to keep him out of the bottom six at the end of Q1.
With Mercedes confirming a right-front brake disc failure, this was the latest blow to a man renowned for his speed over one lap.
Viiew the crash from a number of different angles below:
With Nico Rosberg on pole by two-tenths of a second from his nearest rival on this occasion in Williams' Valtteri Bottas, Hamilton - described as "sore" by Mercedes - faces another exercise in damage limitation on Sunday.
After closing the gap to four points with his win on home soil, that is almost certain to increase again barring any incidents during the race.
Rosberg posted a time of one minute 16.540 seconds to the delight of the German fans, with Bottas joining him on the front row ahead of team-mate Felipe Massa.
Kevin Magnussen starts a fine fourth in his McLaren, equalling his best grid slot of the year achieved in the opening grand prix in Australia.
The Red Bulls of Daniel Ricciardo and four-times champion Sebastian Vettel line up fifth and sixth respectively, with Fernando Alonso in seventh in his Ferrari.
The top 10 is completed by Toro Rosso's Daniil Kvyat, followed by Force India pair Nico Hulkenberg and Sergio Perez in ninth and 10th.
