Solution

1. Preparation

Tools Required: Socket set, torque wrench, brake cleaner, and soft cloths.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Lift the vehicle and secure it with jack stands for safety.

2. Inspect Brake Components

Remove the wheel using a socket set.
Inspect the brake pads:
- Check the thickness and material. If they are performance pads, they may generate more dust.
- Replace with a high-quality low-dust brake pad if necessary.
Examine the brake rotors for any damage:
- Look for scoring or uneven wear. Replace if necessary.

3. Clean Brake Components

Use brake cleaner to clean the brake pads and rotors.
Apply the cleaner to the wheels to remove excess dust.
Wipe down all surfaces with a soft cloth to ensure no residue remains.

4. Reassemble and Test

Reinstall the wheel and torque the lug nuts to the manufacturer’s specification (typically around 80-100 ft-lbs).
Lower the vehicle and perform a test drive to ensure brakes are functioning properly.
