Now this isn't good at all because he almost took out di Resta or Hulkenberg (don't remember who it was) when he lost the car.Narain Karthikeyan's high-speed spin during qualifying for the Korean Grand Prix was caused by his front-right brake disc splitting in half.
"When you first come out of the pits you don't break at first," Karthikeyan told AUTOSPORT.
"I got to the third corner, touched the brakes and it [the brake disc] broke into two.
"I don't know the cause and it was a huge spin."
