CP2649-1 / CP2649-1 - Application Notes



In order to achieve optimum racing brake performance and prolong disc life it is essential that the brakes operate at the correct temperature. In general discs should run at similar temperatures front and rear and from side to side, dissimilar temperatures will lead to varying brake balance.

Under racing conditions disc bulk temperatures should normally be maintained in the range 400°C to 600°C for best performance. Disc face peak temperatures may be higher but should not exceed the maximum recommended for the pad material being used.

An effective method of checking maximum disc operating temperature is by using temperature paints applied to the disc AP racing paint kit contains three paints, Green (turns white at 430°C), Orange (turns yellow at 560°C) and Red (turns white at 610°C) plus thinners and brushes.
