Installation and Fitment Tips

Confirm rear axle fitment by year, make, and model before ordering. Inspect rotors, caliper hardware, and pad contact surfaces during service, and clean the bracket areas before installing the new pads. Because this set includes shims and abutment clips, verify the existing hardware condition and replace any worn components as needed during brake service.
