After Lüthi's arrest on tax fraud charges in mid-1989, several parties disputed the ownership of the team. Middlebridge Group Limited, a Japanese engineering firm owned by billionaire Koji Nakauchi, was already involved with established Formula 3000 team Middlebridge Racing and gained control of Brabham for the 1990 season. Herbie Blash had returned to run the team in 1989 and continued to do so in 1990. Middlebridge paid for its purchase using £1 million loaned to them by finance company Landhurst Leasing, but the team remained underfunded and would only score a few more points finishes in its last three seasons. Jack Brabham's youngest son, David, raced for the Formula One team for a short time in 1990 including the season-ending Australian Grand Prix (the first time a Brabham had driven a Brabham car in an Australian Grand Prix since 1968). 1990 was a disastrous year, with Modena's fifth place in the season-opening United States Grand Prix being the only top six finish. The team finished ninth in the Constructors' Championship. Brundle and fellow Briton Mark Blundell, scored only three points during the 1991 season. Due to poor results in the first half of 1991, they had to prequalify in the second half of the season; Blundell failed to do so in Japan, as did Brundle in Australia. The team finished 10th in the Constructors' Championship, behind another struggling British team, Lotus. The 1992 season started with Eric van de Poele and Giovanna Amati after Akihiko Nakaya was denied a superlicense. Damon Hill, the son of another former Brabham driver and World Champion, debuted in the team after Amati was dropped when her sponsorship failed to materialise. Amati, the fifth woman to race in Formula One, ended her career with three DNQs.
