Williams FW29 - front brake cooling inlets 15 April 2007
At hot races such as Bahrain and Malaysia, one main challenge is to avoid a progressive increase in brake disc temperature. To make it harder, these tracks have multiple, heavy braking points, with little time to cool the brakes inbetween. To ensure efficient cooling Williams have adopted a sophisticated twin inlet design for their front brakes, each inlet directing airflow to separate sections of the disc and calliper. The smaller, upper inlet feeds air mainly to the calliper. The larger, lower inlet directs air to the inner surface of the disc, generating a 'twister' effect in the centre, which helps extract heat via the disc's radial holes.
