* Each disc brake rotor is marked with a minimum thickness dimension. Replace any rotor that does not meet the minimum thickness dimension. **Each disc brake rotor is marked with a unique discard weight. The weight is indicated on the carrier section of the brake rotor, and can vary for each rotor in an axle set.
