Renault R27 - rear rim shields 08 April 2007

These were in use in Australia, but their role is far more relevant in Malaysia due to the severe temperatures. Heat generated under braking by friction between the brake disc and brake pads is dissipated through the small central hole. To avoid problems with brake fading, it is paramount that the working temperature of the discs does not exceed the optimum range. It is very difficult to cool them here due to the track's close sequence of braking points - and the high ambient temperatures. Any solution that can effectively cool the discs will help give the car a well-balanced and efficient braking capability.
