Solution

1. Preparation

Tools Required: Socket set, brake cleaner, jack and jack stands, torque wrench, safety glasses, gloves.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts on the affected wheel.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts.
Carefully slide the caliper off the brake rotor.
Inspect the brake pads for thickness; replace if they are worn down (less than 3mm).
- Sub-steps:
  - Remove old pads by pulling them out of the bracket.
  - Install new brake pads in the same orientation as the old ones.

4. Inspect and Replace Brake Rotors (if necessary)

Check the surface of the brake rotor for scoring or warping.
If the rotor is damaged, remove it by unscrewing the retaining screws.
Install new rotors by aligning them and tightening the retaining screws to the manufacturer's specifications.

5. Reassemble Brake Components

Reattach the caliper over the new pads and rotor.
Secure the caliper bolts to the manufacturer's torque specification.
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and then tighten the lug nuts to the correct torque specification.
