A Brief Discussion on the Forms and Causes of Cracks in Brake Discs by Brake Manufacturers

One reason why brake discs need to be replaced is due to cracks. There are two forms of cracks; One type is cracks generated on the friction surface; Another type is cracks that occur on the heat dissipation ribs.

Due to repeated heating and cooling; Fine cracks on the friction surface begin to develop and propagate near the thin layer of the friction surface. Therefore, cracks occur under high-speed braking or strong braking conditions. Cracks occur on the heat dissipation ribs, which are subjected to tensile, compressive, and bending effects caused by thermal expansion. This type of crack occurs during high-speed braking, strong braking, or prolonged braking.
