Brake rotors typically last between 30,000 and 70,000 miles, though this can vary significantly based on factors such as driving style, road conditions, and vehicle type

. For an average driver putting on about 12,000 miles per year, this translates to roughly 2.5 to 6 years of use before replacement is needed

. Key points about brake rotor lifespan:

• Gentle drivers who mostly do highway driving may see rotors last up to 60,000 miles or more, sometimes even approaching 100,000 miles if conditions are ideal

• City driving with frequent stop-and-go or aggressive braking can wear rotors faster, sometimes requiring replacement as early as 20,000 miles

• Rotors wear more slowly than brake pads, which generally last 30,000 to 70,000 miles, and pads are often replaced multiple times before rotors need attention

• Rotors can sometimes be resurfaced ("turned") to extend their life if they become slightly warped or uneven, but this is limited to a few times before full replacement is necessary

• Signs that rotors need replacement include visible grooves, scoring, cracking, warping, or pulsation felt in the brake pedal during braking

In summary, brake rotors usually require replacement between 30,000 and 70,000 miles, with some lasting longer under ideal conditions and others wearing out sooner due to heavy use or poor driving habits. Regular inspection by a mechanic is the best way to determine rotor condition and timing for replacement
