Solution

1. Preparation

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

2. Remove the Wheel

Use a jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Secure the vehicle with jack stands.
Remove lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the pads; if less than 1/4 inch, replace them.
- Look for metal-to-metal contact indicating severe wear.
Replace Brake Pads:
- Remove the caliper bolts with a socket set and lift the caliper off the rotor.
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are seated properly in the bracket.

4. Inspect and Replace Brake Rotors

Inspect Brake Rotors:
- Check for scoring or grooves on the rotor surface.
- Measure rotor thickness; if below the manufacturer's minimum thickness, replace the rotors.
Replace Brake Rotors:
- Remove the caliper bracket bolts and remove the caliper bracket.
- Slide the rotor off the hub. If stuck, use a hammer to gently tap it free.
- Install new rotors, ensuring they are properly seated on the hub.

5. Reassemble and Test

Reattach the caliper bracket and caliper, tightening bolts to manufacturer’s torque specifications.
Reinstall the wheel and lug nuts, lowering the vehicle back to the ground.
Reconnect the negative battery terminal.
Perform a brake fluid check and top off if necessary.
