Solution

1. Preparation

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

2. Remove Wheel

Use a lug wrench to loosen lug nuts slightly while the vehicle is on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheel completely.

3. Inspect Brake Components

Brake Pads: Remove the brake caliper by unscrewing the caliper bolts. Inspect the brake pads for wear; replace if they are less than 3mm thick.
Rotors: Check the rotors for scoring or uneven wear. Measure thickness with a micrometer; replace if below manufacturer specifications (usually around 24mm for most rotors).
Caliper: Ensure the caliper slides are not sticking. Lubricate with appropriate brake grease if necessary.

4. Replace Brake Pads and Rotors (if needed)

If replacement is necessary, install new brake pads by sliding them into the caliper bracket.
If replacing rotors, remove the old rotor and install the new rotor, ensuring it is seated properly.
Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer’s specification (usually around 25-30 ft-lbs).

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque (typically 80-100 ft-lbs).
Pump the brake pedal to seat the pads against the rotors.
Test the brakes in a safe area to ensure the noise is resolved.
