By lap 10, Ireland had already stormed his way back to fourth, behind McLaren's Cooper, as Moss and Brabham continued to draw away at a second a lap, swapping the lead back and forth. At about one-third distance, on lap 34, Brabham's V8 began to leak water and overheat. With puffs of smoke appearing from the left-side exhaust, the Cooper dropped back from Moss and finally entered the pits on lap 45. After taking on water and returning to the race, Brabham completed only seven more laps before retiring.
