Brabham briefly and unsuccessfully campaigned his own second hand Formula One Maserati 250F during 1956, but his season was saved by drives for Cooper in sports cars and Formula Two, the junior category to Formula One. At that time, almost all racing cars had their engines mounted at the front but Coopers were different, having the engine placed behind the driver, which improved their handling. In 1957, Brabham drove another mid-engined Cooper, again only fitted with a 2-litre engine, at the Monaco Grand Prix. He avoided a large crash at the first corner and was running third towards the end of the race when the fuel pump mount failed. After more than three hours of racing, the exhausted Brabham, who "hated to be beaten", pushed the car to the line to finish sixth. The following year, he was Autocar Formula Two champion in a Cooper, while continuing to score minor points-scoring positions with the small-engined Coopers in the World Drivers' Championship and driving for Aston Martin in Sportscars. His schedule necessitated a considerable amount of travel on the roads of Europe. Brabham's driving on public roads was described as "safe as houses", unlike many of his contemporaries—on the way back from the 1957 Pescara Grand Prix, passenger Tony Brooks took over driving after Brabham refused to overtake a long line of lorries. In late 1958, Brabham rekindled his interest in flying and began taking lessons. He bought his own plane and on gaining his licence began to make heavy use of it piloting himself, his family, and members of his team around Europe to races.
