Williams FW29 - brake ducts 30 September 2007
The unexpectedly cool weather conditions at Fuji did the teams no favours in terms of managing brake temperatures. Most were expecting to use relatively large brake cooling ducts, designed for dry-weather running in warmer temperatures. Sunday's rain and cooler temperatures, however, forced them to either blank off part of the duct opening, or - as Williams did - switch to a smaller duct. Williams also removed the small additional calliper-cooling duct that normally appears on top of the main duct. A similar solution was used at Monza - in that case for drag-reduction purposes.
