While the Brabham BT53 was a strong contender good for 2 race wins, it was far from reliable as often the engine or the turbocharger failed. In sharp contrast to these negatives, Nelson Piquet amassed 9 pole positions during the season, proving that the car had great pace.
The car was however a mere evolution of the Brabham BT52 with minor changes to the position of the turbos and intercoolers. At the Canadian GP, Brabham developed a new frontal oil cooler positioned in the nose of the car. Nelson Piquet immediately won that race but did so with burnt feet, as the temperatures in the cockpit rose immensely because of the added oil cooler.
As of the English GP at Brands Hatch the team ran an updated car, the Brabham BT52B which was a bit sleeker and more performing. Piquet managed to be on pole 5 times with this car in the seven remaining races of the season
