Solution

1. Preparation

Gather necessary tools and parts.
Safely lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the braking components.

2. Inspect Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set.
- Lift the caliper off the brake rotor and support it with a bungee cord (do not let it hang by the brake line).
- Remove the brake pads from the caliper bracket.
- Measure the thickness of the pads; replace if they are below the manufacturer’s minimum thickness.

Tools Required: Socket set, bungee cord.

3. Inspect Brake Rotors

Sub-steps:
- Check the surface of the rotors for grooves or scoring.
- If warped, replace the rotors; otherwise, consider resurfacing if within specifications.

Tools Required: Rotor gauge (if resurfacing), torque wrench for reinstallation.

4. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
- If replacing, install new brake pads into the caliper bracket.
- If rotors are replaced, install the new rotors and torque to specifications.
- Reinstall the caliper over the new brake pads and secure it with caliper bolts.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Pump the brake pedal to ensure proper seating of pads.
Test the brakes at low speed to confirm noise has been eliminated.
