When brake rotors are worn beyond specifications, one of the key issues is that the effectiveness of the entire braking system is compromised. Worn rotors can lead to increased stopping distances, meaning that the vehicle will take longer to come to a complete stop, which can be especially dangerous in emergency situations. This is primarily due to reduced contact area and effectiveness of the brake pads against the rotors, as well as potential overheating and warping of the rotors, which can lead to brake fade.

Additionally, the risk of brake failure increases when rotors are excessively worn. This could happen due to the rotors cracking or becoming too thin, which could lead to structural integrity issues. If the rotors fail while driving, it could result in a sudden loss of braking power, which poses a significant safety hazard for the driver and others on the road.

In contrast, improved braking performance and no change in brake performance are misleading as they suggest enhanced or neutral conditions, respectively, which do not reflect the reality of worn rotors. A squeaking noise might occur due to inadequate contact but does not encapsulate the severe risks posed by substantial wear. Therefore, the primary concerns with rotors worn beyond specifications are indeed increased stopping distances and a heightened risk of brake
