Chrysler 2AMV9994AB Front Disc Brake Rotor

To inspect the brake disc, loosen the wheel lug nuts, raise and support the vehicle on jackstands, and remove the wheel. Reinstall the lug nuts to hold the disc in place, and if working on the rear brake disc, release the parking brake. Remove the brake caliper and pads, but avoid disconnecting the brake hose from the caliper to avoid bleeding the brakes later. Suspend the caliper out of the way with wire. Visually inspect the disc surface for score marks and other damage, addressing deep scoring by removing and refinishing the disc. Check for disc run-out with a dial indicator, and if it exceeds the allowable limit, refinish the disc. The disc should be resurfaced regardless of the indicator reading to ensure a smooth and flat surface, eliminating pulsation. Check the disc thickness with a micrometer to ensure it meets the minimum allowable thickness.
