NO LET UP IN McLAREN’S DEVELOPMENT PACE (Part II)
Working in conjunction with the new front wing, the McLaren brake ducts have also been given an overhaul. The vane has ditched its horseshoe shape for a flatter, more conventional outline. Its base is distorted to create, between the vane and the tyre, an air outlet canal that extends into a bent fin (instead of an horizontal one) in a manner similar to the Red Bull. As for the duct itself, it is now located on the outside of the fin and not on the inside.
The brake drums have been modified once again, with an oversized outlet discharging the hot air. The gradual evolution in the design of the drums – from the small water drop-shaped holes to the intermediate solution seen in Sochi – shows that McLaren is trying to exploit the airflow differently in this area.
