Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Wheel Removal

Loosen lug nuts on the affected wheel while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Check the thickness of the brake pads. If they are worn down to 3mm or less, they should be replaced.
Replacement:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
- Remove the old brake pads from the caliper bracket and replace them with new ones. Ensure they are correctly positioned.

4. Inspect and Replace Brake Rotors (if necessary)

Check the surface of the rotors for grooves or warping.
If rotors are damaged, remove the caliper bracket to access the rotor.
Remove the rotor by unscrewing the retaining screws (if applicable) and pulling it off the hub.
Install new rotors, ensuring they are properly seated.

5. Reassemble Brake Components

Reattach the caliper bracket and torque bolts to the manufacturer's specifications.
Reinstall the caliper over the new pads and torque caliper bolts to the specified value.
Reinstall the wheel, hand-tightening the lug nuts.

6. Final Checks

Lower the vehicle and tighten the lug nuts to the specified torque.
Refill brake fluid if necessary, ensuring proper fluid level.
