• Fitment issues when replacing an original drum-in-hat rear rotor

Installation Notes and Tips

Confirm rotor dimensions, bolt pattern, and caliper type before installation. BR3203 is a rear, solid, drum-in-hat rotor, so it should be matched to the exact Mercedes-Benz model year and brake configuration listed above. Clean the hub mounting surface before installation and verify rotor runout after assembly for proper brake performance.
