In 2000, he switched to the CART circuit, finishing as runner-up in 2001, but came back to IRL on 2003. In the final race at Texas Motor Speedway, he suffered a serious crash that almost cost him his legs. His car locked wheels with Tomas Scheckter's car, that sent Bräck's car flying into the catch fencing and it broke apart. After recovering from his injuries, he raced in the 2005 Indianapolis 500, replacing an injured Buddy Rice who effectively replaced him in the 2004 race, although this appears likely to be his final race.
As of 2006, Brack lives in Belgium and has retired from open wheel racing. Brack spends most of his time currently as the lead member of a rock band.
