What is the consequence of cracked rotors extending to the edge during an inspection?

Cracked rotors extending to the edge during an inspection indicate that the structural integrity of the rotor has been compromised. Rotors play a critical role in the vehicle's braking system, and any significant damage, particularly cracks that reach the edge, can greatly affect braking performance and safety.

When the cracks extend to the edge, there is a risk of further deterioration that could lead to brake failure, posing a serious risk to the driver and others on the road. Therefore, such a condition is classified as an automatic failure during an inspection, since the vehicle would not meet the safety standards required for roadworthiness. Ensuring that the braking system is fully operational is crucial for the safety of all road users, making it essential for the vehicle to fail inspection under these circumstances.
