Peter Gethin
As the race continued, Reine Wisell passed Peterson and was catching Ickx when he pitted with brake problems. Wisell lost two laps while his brakes were bled. Peterson himself encountered a clutch fault and began to fall further behind Ickx. Peter Gethin retired on lap four with a broken throttle, and John Miles had to retire three laps later with an engine fault. Ray Allen dropped out at the back of the field with a fuel leak on lap 15.
