Brise won his first UK championship in 1969, and switched to single-seater racing the next year, driving an Elden MK8 Formula Ford. In 1971, he placed second in the BOC British FF1600 Championship. While completing a BSc in Business Administration at
Aston University, he chose to continue with motor racing, joining Formula 3 in 1972 driving a Brabham BT28, the team run by
Bernie Ecclestone. as well as winning the John Player. At the end of the season he won a
Grovewood Award for the second time, shared with
Tom Pryce. Brise wished to move up to
Formula 2 for the 1974 seasons, but was unable to due to financial limitations. Instead, he bought a second-hand
March 733 car, fitting it with a
Holbay-tuned Ford and entering the MCD
Formula Atlantic series. He won the first round of the British Championship unexpectedly, but subsequently wrote the car off in a crash at
Snetterton. However, his performance had brought him to the attention of Teddy Savory of Modus, who offered him a work drive in the series. Although the car was another modified F3 chassis, he drove well enough to earn a drive in a purpose-built car in 1975. He also drove a Modus M1 F3 in the Monaco Grand Prix F3 support race, finishing second behind Tom Pryce in a March 743. Brise excelled in the new car in 1975, winning six consecutive races, at Snetterton,
Oulton Park, and twice each at
Brands Hatch and
Silverstone, enough to win him the MCD International
Formula Atlantic Championship. As a result of these achievements, he was contacted by
Frank Williams in April, to make his Formula One debut standing in for
Jacques Laffite. ==Formula One career==
