Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Disconnect the battery to prevent electrical shorts.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts of the wheel to be serviced.
Lift 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; replace if less than 3 mm.
- Look for uneven wear patterns.
Replacement:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it (do not hang it by the brake line).
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly aligned.
- Reinstall the caliper and torque the bolts to manufacturer specifications (typically around 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if needed)

If the rotors show signs of scoring or are below the manufacturer’s minimum thickness, replace them.
Remove the caliper bracket if needed to access the rotor.
Slide the old rotor off the hub.
Install the new rotor, ensuring it is seated properly.
Reinstall the caliper bracket if removed.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (typically 76-83 ft-lbs).
Reconnect the battery.
Pump the brake pedal several times to seat the brake pads.
Test drive the vehicle at low speeds to ensure the noise is eliminated.
