Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety gear such as gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle based on where the noise is coming from.
Secure with jack stands to ensure stability.

3. Remove the Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Keep the lug nuts in a safe place for reinstallation.

4. Inspect and Replace Brake Pads

Inspection: Check the thickness of the brake pads; replace if less than 3mm.
Replacement:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang from the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads into the caliper bracket, ensuring proper orientation.

5. Inspect and Replace Brake Rotors (if necessary)

Inspection: Check for warping or scoring on the rotor surface.
Replacement:
1. Remove the caliper bracket bolts and detach the caliper bracket.
2. Slide off the rotor (may require tapping with a rubber mallet if stuck).
3. Install the new rotor, ensuring it sits flush against the hub.
4. Reattach caliper bracket and torque bolts to manufacturer specifications (typically around 70-90 lb-ft).

6. Reassemble and Test

Reinstall the caliper and tighten bolts to manufacturer's specifications.
Reattach the wheel and hand-tighten lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specification (usually between 76-100 lb-ft).
Pump the brake pedal a few times to seat the new pads.
