Vehicles equipped with the brake sales code BR3 (Performance Disc/Disc brake combination) use heavier brake rotors. The BR3 front brake rotor is approximately 6 mm thicker than the standard front brake rotor. The BR3 rear brake rotor is approximately 3 mm thicker than the standard rear brake rotor. The BR3 brake rotors can be easily identified by the recessed machined area near the hub center (Fig. 118) (Fig. 119).
