Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Wear safety glasses and gloves.

2. Raise the Vehicle

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

3. Remove the Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.

4. Inspect and Replace Brake Pads

Inspect Pads: Check the thickness of the brake pads. If they are less than 3mm, replace them.
Remove Pads: Use a socket set to remove the caliper bolts and gently slide the caliper off the rotor.
Replace Pads: Install new brake pads, ensuring they are seated properly in the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Check Rotors: Look for signs of scoring or warping. If found, the rotors should be replaced.
Remove Rotors: Remove the rotor retaining screws (if equipped) and slide the rotor off the hub.
Install New Rotors: Place the new rotor onto the hub and secure it with screws.

6. Reassemble the Brake Components

Reattach the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.

8. Test the Brakes

Pump the brake pedal a few times to seat the pads.
Check for any unusual noises or issues.
