Solution

1. Preparation

Tools Required: Socket set, jack stands, lug wrench, brake cleaner, torque wrench
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are making the noise.
Secure the vehicle with jack stands to ensure stability.

3. Remove Wheel Assembly

Use a lug wrench to remove the wheel nuts and take off the wheel.
Ensure the wheel is placed safely aside for reinstallation later.

4. Inspect and Replace Brake Pads

Sub-steps:
- Remove the brake caliper by unscrewing the caliper bolts with a socket set.
- Carefully slide the caliper off the rotor and suspend it with a bungee cord or rope to avoid straining the brake line.
- Remove the old brake pads from the caliper bracket.
- Inspect the brake pad backing for wear indicators and replace if they are worn down to the indicator line.
- Place new brake pads into the caliper bracket, ensuring they are correctly positioned.

5. Inspect and Replace Brake Rotors (if necessary)

Check for any visible damage on the brake rotors. If they are scored or warped, they need replacement.
Remove the rotor by loosening the retaining screws (if applicable) and sliding it off the hub.
Install the new rotor, ensuring it is properly seated.

6. Reassemble Brake Components

Reattach the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer's specified torque value (typically around 20-30 ft-lbs, but consult service manual for specifics).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

7. Lower the Vehicle and Test

Remove jack stands and lower the vehicle.
Tighten the lug nuts in a criss-cross pattern to ensure even pressure.
Pump the brake pedal several times to seat the brake pads before test driving.
