Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

Tools Required:

Jack and jack stands
Lug wrench
Brake cleaner
Socket set
Torque wrench

2. Remove Wheel

Loosen the lug nuts on the wheel where the noise is present.
Use the jack to lift the vehicle and place it securely on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the socket set.
Carefully slide the caliper off the rotor and support it (do not let it dangle by the brake line).
Remove the old brake pads from the caliper bracket.
Inspect the brake pads for wear; if they are below the manufacturer’s recommended thickness, replace them.
Install new brake pads in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor for any scoring or warping using a straight edge.
If the rotor surface is damaged beyond acceptable limits, it must be replaced.
Remove the rotor by unscrewing any retaining bolts; clean the hub surface.
Install new rotor and torque bolts to the manufacturer's specifications.

5. Reassemble and Test

Reattach the caliper over the new brake pads and torque the caliper bolts to the specified torque setting.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and fully tighten the lug nuts in a crisscross pattern to ensure even tightening.
