Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle with a jack and secure it on jack stands.
Remove the wheel completely.

3. Inspect and Replace Brake Rotors

Inspection: Use a dial indicator to check for rotor warpage.
Replacement:
- If warped, remove the caliper brackets using a socket set.
- Remove the brake caliper and hang it securely using wire to avoid stress on the brake line.
- Remove the rotor; it may require a hammer to dislodge if it's stuck.
- Install the new rotor, ensuring it is seated properly.
- Reinstall the caliper and brackets, tightening to the manufacturer's torque specifications (typically around 75-85 ft-lbs).

4. Inspect and Replace Brake Pads

Check the thickness of the brake pads; if below 3mm, replace them.
Remove the old brake pads from the caliper bracket.
Apply brake grease to the back of the new pads to reduce noise.
Install the new pads securely in the caliper bracket.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the manufacturer’s torque specifications (typically around 100-150 ft-lbs).
Test drive the vehicle at low speeds to check for any remaining vibrations.
