Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise originates.
Secure the vehicle on jack stands for safety.

3. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set and slide the caliper off.
- Check the brake pad thickness; if less than 3mm, replace them.
Replace Brake Pads:
- Remove the old pads from the caliper bracket.
- Apply anti-squeal lubricant to the back of the new brake pads.
- Install the new brake pads into the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check the rotors for scoring, rust, or warping.
Replace Rotors:
- If damaged, remove the caliper bracket from the rotor.
- Remove the old rotor and install the new rotor, ensuring proper alignment.
- Reinstall the caliper bracket with torque specifications provided by the manufacturer.

6. Reassemble Components

Slide the caliper back over the new brake pads and secure it with bolts.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Remove jack stands and lower the vehicle back to the ground.
Tighten the lug nuts to the specified torque value in a star pattern.

8. Brake Fluid Check

Check brake fluid level and top off if necessary with the manufacturer's recommended fluid.

Tools Required:

Socket set
Torque wrench
Brake pad spreader
Brake cleaner
Anti-squeal lubricant
Jack and jack stands

Parts Required:

New brake pads
New brake rotors (if necessary)
Brake fluid

Estimated Repair Time: 2-4 hours
