Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel corresponding to the affected brake system.
Raise the vehicle with a jack and secure it on jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads. If they are below 3mm, they must be replaced.
Remove Brake Caliper:
- Use a socket set to remove the caliper bolts.
- Carefully slide the caliper off the rotor and hang it using a bungee cord or wire (do not let it dangle from the brake line).
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket with brake cleaner and a brush.
- Install new brake pads in the caliper bracket, ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for any grooves, scoring, or excessive wear. Measure rotor thickness with a micrometer.
Remove and Replace Rotors:
- If replacement is needed, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Clean the hub surface with a wire brush.
- Install new rotors, ensuring they are properly aligned and secured.

5. Reassemble Brake Components

Reattach the brake caliper over the new pads and rotor.
Torque caliper bolts to manufacturer's specifications (typically between 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands and remove the jack.
Tighten lug nuts to the manufacturer's specified torque (usually around 100 ft-lbs).
Reconnect the negative battery terminal.
