Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Safety warning: Wear safety glasses and gloves.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel with the affected brake.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; replace if they are below the minimum thickness (usually around 3mm).
Remove Brake Caliper:
- Use a socket set to remove the bolts securing the brake caliper.
- Carefully slide the caliper off the brake rotor and secure it with a bungee cord to avoid strain on the brake line.
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Apply brake grease to the back of the new pads to prevent squeaking.
- Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors if Necessary

Inspect Rotors:
- Check for any grooves or warping on the rotors.
Remove Brake Rotor:
- If replacement is needed, remove the retaining screws (if applicable) and slide the rotor off the hub.
Install New Rotor:
- Place the new rotor onto the hub and secure it with retaining screws if applicable.

5. Reassemble Brake System

Reattach Caliper:
- Carefully slide the caliper back over the new pads and rotor.
- Reinstall caliper bolts and torque to manufacturer specifications (usually around 25-30 ft-lbs).
Reinstall Wheel:
- Place the wheel back onto the hub.
- Hand-tighten the lug nuts and then lower the vehicle.
- Use the torque wrench to tighten lug nuts to manufacturer specifications (usually around 76-80 ft-lbs).

6. Test Brakes

Pump the brake pedal a few times to seat the pads against the rotor before driving.
Recheck brake fluid level and top off if necessary.
