A: To inspect the brake disc, start by loosening the wheel lug nuts, raising the vehicle, and securing it with jackstands. Remove the wheel and then the Brake Caliper without disconnecting the brake hose; hang the caliper safely using a piece of wire, ensuring it doesn't hang by the hose. In 4WD models, retain the disc in place with two lug nuts. Visually examine the disc surface for damage, checking for score marks and deep grooves, which may require disc removal and refinishing by an automotive machine shop. Verify both sides of the disc and investigate disc runout by using a dial indicator to ensure it doesn't exceed allowable limits. For 4WD or 1993 and later 2WD vehicles, remove the retaining lug nuts, slide off the disc, and replace it. When installing, adjust the wheel bearing as necessary, ensuring proper cleaning and repacking if the disc was machined. On 4WD models, simply position the disc over the wheel studs. Reinstall the caliper and Brake Pad assembly over the disc, secure it on the steering knuckle, and tighten the caliper mounting pins to the specified torque. Reinstall the wheel, lower the vehicle, and depress the brake pedal several times to establish contact between the brake pads and the disc. Brake system bleeding is only required if the brake hose was disconnected. Thoroughly assess brake operation before returning the vehicle to normal service.
