Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the ignition is off.
Gather necessary tools and parts.
Secure the vehicle with wheel chocks and jack stands.

2. Remove Wheel

Loosen the lug nuts on the wheel where the noise is coming from using a socket set.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket set.
Carefully slide the caliper off the brake pads and hang it using a bungee cord (do not let it dangle from the brake line).
Check the thickness of the brake pads; if they are worn below 3mm, replace them.
Remove the old pads and install new pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotors for wear or scoring; if they appear damaged or below the minimum thickness, replace them.
To remove the rotor, remove any retaining screws and slide the rotor off the hub.
Install the new rotor, securing it with screws if applicable.

5. Reassemble Components

Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and torque the lug nuts in a crisscross pattern to the specified torque value.
Lower the vehicle back to the ground.
