Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, torque wrench, caliper tool, and a runout gauge.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspection: Use a runout gauge to check the rotor for warping. If the runout exceeds manufacturer specifications, replace the rotor.
Replacement:
1. Remove the caliper bolts and carefully slide the caliper off the rotor.
2. If applicable, remove the caliper bracket by unscrewing the mounting bolts.
3. Remove the old rotor and clean the hub surface to ensure a flat mounting surface.
4. Install the new rotor, ensuring it is correctly seated.
5. Reinstall the caliper bracket and caliper, tightening bolts to the manufacturer's specified torque.

4. Inspect and Replace Brake Pads

Check the condition of the brake pads. If they are worn or damaged, proceed to replace them.
Replacement:
1. Remove the caliper using the same method as above.
2. Use a caliper tool to compress the caliper piston back into the caliper housing.
3. Replace the old pads with new ones, ensuring they are correctly oriented.
4. Reinstall the caliper and torque the bolts to the specified value.

5. Reassemble and Lower Vehicle

Reinstall the wheel and tighten lug nuts by hand.
Lower the vehicle from the jack stands and ensure it is on the ground.
Use the torque wrench to tighten the lug nuts to the manufacturer's specified torque.
