Despite taking pole position in the first two rounds, mechanical problems halted his chances of victory. He spun numerous times in South Africa, and at Monaco, his engine blew up at the start, and the win went to his teammate Denny Hulme. At the Dutch Grand Prix, he scored his first podium of the season, with second place, behind Scotsman Jim Clark. He retired in the Belgian Grand Prix with another blown engine. He fixed this by winning the French Grand Prix at the Bugatti Circuit in Le Mans. He came fourth at the British Grand Prix, behind Chris Amon, his teammate Hulme, and Clark. At the German Grand Prix, he had a huge battle with Amon, and Brabham eventually finished ahead of the New Zealander, by only half a second. Hulme was the winner. At the first ever Canadian Grand Prix at Mosport Park, he took a huge win, ahead of Hulme, in cold and rainy conditions. At the Italian Grand Prix at Monza, Brabham had to finish second, only a few car lengths behind John Surtees, who took his last GP win. Hulme retired from the race, cutting the gap to 3 points between the two, as the circus headed for the United States, at Watkins Glen for the United States Grand Prix. Brabham outqualified his teammate, and finished fifth in the race, and with Hulme on the podium, this meant the championship chances were looking slim for Black Jack, as the circus went to Mexico for the championship deciding and final race of the season. Once again, he outqualified his teammate, and needed to win, with Hulme fifth or lower. But Jim Clark was simply too fast during the whole weekend, and dominated the race from pole to win, with Brabham finishing over 1 minute and 25 seconds behind. Hulme finished third, and so the New Zealander won the championship, while Brabham settled for second place. The team secured the Constructors' Championship, with 67 total points scored, and 23 points ahead of Lotus which scored a total of 44 points.
