Chrysler 4509553AB Brake Rotor

Loosen the wheel lug nuts, raise the front or rear of the vehicle, and support it securely on jackstands while applying the parking brake. Remove the front or rear wheels and reinstall the lug nuts with the flat side toward the disc to hold it firmly against the hub. Remove the brake caliper and visually inspect the disc surface for score marks and other damage; deep grooves over 0.015-inch require disc removal and refinishing by an automotive machine shop, while light scratches and shallow grooves are normal. To check disc runout, place a dial indicator about 1/2-inch from the outer edge of the disc, set it to zero, and turn the disc, ensuring the reading does not exceed the specified runout limit; if it does, the disc should be refinished. It is recommended to resurface the brake discs to eliminate brake pedal pulsations, and if not resurfaced, deglaze them with sandpaper or emery cloth. The disc must not be machined to a thickness less than the specified minimum thickness, which is cast into the disc and can be checked with a micrometer at several points. For removal, loosen the wheel lug nuts, raise the vehicle, and place it securely on jackstands before removing the wheel. If removing a rear disc, block the front wheels and release the parking brake. Remove the caliper and any retaining clips from the wheel studs, then pull the disc off the hub. If the rear disc won't come off, remove the plug from the parking brake adjusting access hole and turn the adjusting star wheel to retract the parking brake shoes. Installation is the reverse of removal, ensuring the caliper guide pin bolts are tightened to the specified torque.
