Jack Brabham
Brabham cars were designed and built by Motor Racing Developments Ltd. (MRD), which was jointly owned by Tauranac and Jack Brabham and built cars for customers in several racing series. The Formula One racing team, BRO, was a separate company wholly owned by Jack Brabham. It bought its cars from MRD but Tauranac had little connection with the race team between 1962 and 1965.
