Tuhia he haere tonu mō tēnei rārangi - I whakakapia e Brabham a Schenken ki a Carlos Reutemann nō Argentina mō te tau 1972. I noho tonu a Hill ki te kapa, engari i tukuna e Brabham te Argentinian ki te BT34. I te 1972 Argentine Grand Prix i kite a Reutemann i te pou i tana Grand Prix tuatahi engari i mutu i te tuawhitu. Ko te Argentinian i reti mai i Awherika ki te Tonga me te ngoikoretanga o te punaha wahie. I whati a Reutemann i tana waewae i muri i te ngoikoretanga miihini i runga i tana Rondel Racing i uru atu ki Brabham i Thruxton i te wa o te whakataetae Formula Tuarua. Kaore i whakamahia te BT34 i te Spanish me Monaco Grand Prix. Mo Belgium, i uru a Brabham ki te waka tuatoru mo te Brazil Wilson Fittipaldi, engari i reti ia me te pouaka nekehanga pakaru. I mutu te tangata Brazil i te tuawaru i te French Grand Prix. I mutu a Fittipaldi i te tekau ma rua i Ingarangi ahakoa i mutu tana motuka i te huringa 69 me te aukati pakaru. Ko te tangata nō Pirihimana te tuawhitu i te Whakataunga Nui o Tiamana. I mutu a Fittipaldi i ngā whakataetae e whā whakamutunga o te tau, i pakaru te parahi i Austria, i pakaru te whakaahunga i Itari
, kua pakaru te pouaka nekeneke i Canada me te ngoikoretanga o te miihini i te United States.
