Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on the braking system.

2. Wheel Removal

Using a lug wrench, loosen the lug nuts on the wheel where the noise is occurring.
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Brake Pad Replacement

Tools Required: Socket set, torque wrench, brake cleaner, anti-seize lubricant
Remove the caliper bolts using a socket.
Carefully slide the caliper off the rotor and support it with a bungee cord to avoid stressing the brake line.
Remove the old brake pads from the caliper bracket. If they are worn down, replace them with new pads.
Apply brake cleaner to the caliper bracket and rotor to remove any dust and debris.
Install the new pads into the caliper bracket.

4. Brake Rotor Inspection/Replacement

Check the rotor for any signs of wear or damage. If the rotor is warped or scored, it should be replaced.
If replacing, remove the rotor by unscrewing the retaining bolts (if applicable) and sliding it off the hub.
Install the new rotor onto the hub and secure it with the retaining bolts (torque to manufacturer specifications).

5. Reassemble and Test

Reinstall the caliper over the new pads and rotor, ensuring it slides easily.
Replace and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified torque.
Reconnect the battery.
