Trouble Shooting Brake Rotor Problems

Description of the defect: The disc has been subjected to excessive operating temperatures: in the outer area of the braking surface there are evident signs of overheating. High operating temperatures lead to the appearance of cracks.

Consequences: Distortion and pad "bouncing" when hot that causes vibrations during braking. With time, cracks form and the disc may break.

Advice: The worn disc must be replaced. Check the state of wear periodically.
