Jeep 2AMV4762AC Front Brake Rotor

Loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands while applying the parking brake, then remove the wheels. Visually inspect the disc surface for score marks and other damage; severe wear indicates the disc must be replaced, while light scratches and shallow grooves are normal and won't affect brake operation. To check disc runout, place a dial indicator about 1/2-inch from the outer edge of the disc, install the lug nuts with flat sides facing in, and tighten them securely. Set the indicator to zero and turn the disc, ensuring the reading does not exceed the runout limit; if it does, the disc should be refinished, or alternatively, deglazed 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. Remove the brake caliper without disconnecting the brake hose and hang it out of the way, then take off the caliper mounting bracket retained by two bolts. Remove the lug nuts and pull the disc off the hub, cutting off any retainers holding the disc in place if necessary. Installation is the reverse of removal, ensuring the caliper mounting bracket fasteners are tightened to the specified torque, followed by lowering the vehicle and tightening the wheel lug nuts to the appropriate torque.
