Brake rotors typically need to be replaced every 50,000 to 70,000 miles, but the actual lifespan depends on several factors, including:
Signs That Brake Rotors Need Replacement:
- Vibration or Pulsation: If your steering wheel or brake pedal shakes when braking, the rotors may be warped or uneven.
- Squealing or Grinding Noise: A high-pitched squeal or grinding sound could mean the rotor surface is damaged or excessively worn.
- Visible Scoring or Grooves: Deep grooves or heat spots on the rotor surface indicate wear and overheating, reducing braking efficiency.
- Increased Stopping Distance: If your car takes longer to stop, worn rotors may be reducing brake performance.
- Thickness below Minimum Spec: Rotors have a minimum thickness. If they are too thin, they lose heat dissipation ability and must be changed.
Other Considerations:
- Driving styles: Aggressive braking wears rotors faster.
- Brake pad quality: Hard pads may wear rotors sooner.
- Environment: Frequent stop-and-go traffic or mountainous terrain can accelerate rotor wear.
Replace or Resurface?
- Resurfacing is only possible if the rotor is thick sufficient and not heavily scored or warped.
- Replacement is better for severely worn, warped, or thin rotors.
