Williams FW34 - brake ducts 24 March 2012 Brake ducts are being
used more and more by the teams for aerodynamic benefit. The
front ducts are used to improve the flow of air in the space
between the tyre and the chassis, whilst the rear ducts are used
to boost downforce. Williams (and subsequently Sauber) have
introduced front ducts without an inlet. The British team have
also added a small turning vane to improve airflow efficiency.
