Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Brake cleaner
- Torque wrench
- Allen wrench set (for caliper removal)
- Safety glasses and gloves
Safety Warnings:
- Ensure the vehicle is on a flat surface and engage the parking brake.
- Allow the brakes to cool before inspection.

2. Remove Wheel

Loosen lug nuts slightly while the car is still on the ground.
Jack up the vehicle and secure with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Check the thickness of the brake pads. Replace if below manufacturer specifications (typically less than 3mm).
Brake Rotors:
- Inspect for any scoring, warping, or uneven wear. Replace if necessary.
Calipers:
- Ensure the caliper is not sticking. Clean any debris or corrosion around the caliper and piston.

4. Clean Brake Parts

Spray brake cleaner on the brake pads, rotors, and calipers to remove dust and debris.
Wipe down with a clean cloth.

5. Reassemble Components

If brake pads or rotors were replaced, install new components, ensuring proper alignment.
Secure the caliper and torque bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and torque lug nuts to manufacturer specifications (usually around 100-120 ft-lbs).

6. Test Drive

Lower the car and remove jack stands.
Conduct a short test drive to ensure brakes are functioning properly and listen for any remaining noise.
