Brake Rotors: lifespan, maintenance and replacement

Typical lifespan: 50,000–70,000 miles.

Maintenance schedule

• Measure rotor thickness — With every brake pad change
• Diagnose runout, thickness variation, cracks and surface damage — With vibration or brake service

Signs it needs replacing

• Pulsation or vibration when braking
• Visible grooves or scoring on surface
• Rotor below minimum thickness
• Blue discoloration from overheating

Tips

Follow the manufacturer's axle-service procedure. Resurfacing is only appropriate when permitted and the finished rotor meets the applicable thickness specification.
