how often do rotors need to be replaced

Brake rotors generally need to be replaced approximately every 50,000 to 110,000 miles, depending on driving habits, vehicle usage, and environmental conditions. More specifically, most rotors last about 50,000 to 70,000 miles on average, but factors like aggressive driving, towing, frequent braking, and harsh environments can accelerate wear and require more frequent replacement. It's advisable to inspect rotors whenever brake pads are replaced, looking for signs such as warping, deep grooves, rust, blue tint, or if the rotor thickness falls below the manufacturer's minimum specification. If rotors are warped or too thin to be resurfaced, they should be replaced. Regular inspection roughly every 16,000 km (about 10,000 miles) is recommended for safety and optimal brake performance.
