If there is any cracking, it can result in a structural failure of the rotor.

It might not look like it, but a brake rotor is one of the most stressed components on any car or truck. It’s not the plates that are under the most stress, but where the plates meet the hat of the brake rotor. If there is any cracking, it can result in a structural failure of the brake rotor. While doing a brake rotor safety inspection, it is essential to look for cracks in this area. In this video, Andrew Markel looks at how to inspect rotors for cracks, thickness and runout.
