Ferrari F14 T - front brake cooling, part one 06 July 2014

The airflow that cools the front brakes needs to be very well managed. The cold air comes in the main forward-facing brake duct opening (centre of picture) and passes through the cooling holes and across of the hot brake disc, taking away the excess heat. This airflow is then exited (red arrows) through the spokes of the front wheel and then mixes with the airflow that is coming around the outside of the front tyre. If any of this hot turbulent airflow is allowed to escape inside the wheel, the car's underfloor will produce less downforce, meaning the car will have less grip.
