• Service replacement for Mercedes-Benz rear brake maintenance

Installation Notes and Tips

Verify rotor diameter, thickness, and bolt pattern against the vehicle before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake vibration, and inspect pads and caliper hardware at the same time to avoid uneven wear. Confirm rear-position fitment for the exact Mercedes-Benz model and trim, including AMG Package applications where noted.
