Jack arrived at Indy in 1961 with the first rear-engined car for the race. The Cooper Climax was down on power compared to the roadsters, but was much faster through each turn.
Unfortunately Jack struggled with tire wear and was forced to make extra pit stops. He eventually finished ninth after qualifying 13th, but believed he had a car to finish at least fifth. The arrival of Jack’s car started a rear-engine revolution in the sport which exists to this day.

After a couple of years away from the Speedway, Jack returned in 1964 to qualify 25th in one of his own cars.
On the second lap of the race, Jack drove through a dramatic seven-car crash which claimed the lives of Eddie Sachs and Dave McDonald. It is thought that the heat generated from that crash weakened the fuel tank on Jack’s car and it eventually started to leak. Jack had started the race cautiously because he was beginning the race near the McDonald car.
Masten Gregory had refused to drive the car because it was too dangerous and McDonald took the seat which would claim his life. Brabham, who was the only international driver in the race alongside Jim Clark, lasted 77 laps and was classified in 20th spot.

In 1969, not one front-engined car qualified for the race and they never would again. The revolution started by Jack in 1961 was complete.
Jack came to Indy with his Repco-powered Brabham and while the combination was good enough to win him his third F1 title in 1966, he struggled in qualifying and would start 29th. The nagging ignition problems would force him from the race on lap 59.
This is the year that Mario Andretti would win his one and only Indy 500.

In his last appearance at the Speedway, Jack qualified his Brabham Offy in 26th spot. He ran strongly in the race until he burned a piston just 25 laps from home and was classified 13th. Jack was again the only international driver in the race. Stock car driver LeeRoy Yarborough would then drive the Brabham in the California 500 at the Ontario Speedway three months later and was leading with nine laps to go when he also suffered an engine failure and was classified ninth.
