The heat treatment does not directly improve brake performance. The heat treatment increases the disc resistance against strains and thermal cracking. It also helps maintain stable brake performance for a extended period of time.
_x000D_ The surface of the heat treated brake discs has a burnt colour. Once it is used, the burnt surface will be removed by the pad, and changes back to the colour of normal cast iron. Please be aware that the effect of the heat treatment of the disc will not disappear even if the surface colour changes.
