Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Loosen the lug nuts on the affected wheel using a socket wrench.
Use a jack to lift the vehicle and securely place jack stands beneath.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper by unscrewing the caliper bolts with a socket wrench.
- Carefully slide the caliper off the brake pads and hang it using a wire to avoid stress on the brake line.
- Check the brake pads for wear; if they are less than 3mm thick, they should be replaced.
Replacement:
- Remove old brake pads from the caliper bracket.
- Install new brake pads in the caliper bracket ensuring they are seated properly.
- Reinstall the caliper over the new pads and secure with caliper bolts. Torque to the manufacturer's specifications (typically around 25-30 Nm).

4. Inspect and Replace Brake Rotors (if necessary)

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

5. Final Assembly

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and tighten the lug nuts to the manufacturer’s torque specifications (typically 100-120 Nm).
Reconnect the battery.
