Scoring or grooves on brake rotors indicate potential failure because they can compromise the braking system's efficiency and safety. When rotors exhibit these signs, it often means that the rotor surface has become uneven due to friction from brake pads that are either worn down or have hardened. This uneven surface can lead to decreased contact between the rotor and brake pads, resulting in increased stopping distances and reduced braking performance. If not addressed, this situation can escalate to more serious issues, including rotor warping or complete brake failure, which poses significant safety risks while driving. It is crucial for inspectors to identify such conditions early to recommend necessary repairs or rotor replacement to ensure the vehicle operates safely.
