How often should one replace brake rotors to ensure optimal vehicle performance and safety? Is there a specific mileage or time interval that mechanics generally recommend, or does it depend on various factors such as driving style, road conditions, and the type of vehicle? What are the telltale signs that indicate that the brake rotors may be deteriorating, and how can one ascertain whether the rotors have reached their limit? Should one consider not just the thickness of the rotors but also factors like warping or scoring on the surface? Is there a significant difference in lifespan between OEM and aftermarket rotors, and how might performance vary under different circumstances? Are there specific habits or maintenance routines that could extend the lifespan of brake rotors? Ultimately, how does one balance cost considerations with safety implications when it comes to replacing brake rotors in a timely manner?
