Racing in IndyCar is highly demanding on the brake system. The vehicles on track can regularly see temps reaching 900°C or higher which must be cooled down before the next application. The brake system has ducts that force air into the rotors and calipers when running so the heat can be dissipated. The issue is when the car stops the brakes heat soak. Keeping the brakes cool while in the pits is imperative to maintaining the integrity of the brake system. The fans must be easy to install and remove to keep in line with the very tight schedules demanded of the team during the sessions.
