Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety glasses, gloves.
Park the vehicle on a flat surface, engage the parking brake, and ensure the engine is off.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are making noise.
Secure the vehicle with jack stands to prevent it from falling.

3. Remove the Wheel

Use a lug wrench to loosen the lug nuts and remove the wheel.
Place the wheel aside in a safe location.

4. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Inspect the brake pads for thickness; if they are below 1/8 inch, replace them.
Brake Rotors:
- Check the rotor surface for any grooves or scoring. If damaged, they should be resurfaced or replaced.
Calipers:
- Ensure the calipers move freely and are not stuck. Lubricate sliding pins if necessary.

5. Replace Components (if needed)

If pads or rotors are worn:
- Remove the old brake pads and install new ones, ensuring they are positioned correctly.
- If replacing rotors, remove the old rotor and install the new one, ensuring it is securely fastened.

6. Reassemble

Reattach the caliper over the new pads and rotor, tightening the caliper bolts to manufacturer specifications (usually around 25-35 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque (usually around 80-100 lb-ft).
