Kimi Raikkonen's run of 27 points-scoring finishes came an end at Spa when the four-time Belgian GP winner retired with suspected brake failure.
Raikkonen, who has a tendancy to either win or retire in Belgium, was forced out of the grand prix on lap 26 when he ran off the track in his pursuit of Felipe Massa.
Trying to overtake the Ferrari driver at the Bus Stop chicane, Raikkonen instead went straight on and then straight into the pits after reporting "brake failure" over the radio.
The Lotus driver's DNF brought to an end his record of 27 grands prix inside the points and was also his first retirement since Germany 2009.
"Some days you run out of luck and today it was our turn," said the Finnish driver.
"I don't know if it was the brakes. It was not a problem until now but we need to check."
Raikkonen's first retirement since the 2009 German GP has dropped him to fourth in the Drivers' Championship where he trails Sebastian Vettel by 63 points.
