Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on brake components.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel with excessive brake dust using a lug wrench.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper by unscrewing the caliper bolts with a socket set.
- Slide the caliper off the rotor and support it to avoid straining the brake line.
- Check the brake pads for uneven wear. If one pad is significantly thinner, it may need replacement.
Replace Brake Pads:
- If replacement is needed, remove the old pads.
- Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Clean Brake Rotor

Inspect Rotor:
- Check the rotor for any scoring, warping, or excessive wear. If damaged, it should be resurfaced or replaced.
Clean Rotor:
- If rotor is in good condition, clean it with brake cleaner to remove any dust or residue.

5. Reinstall Components

Reattach the caliper over the new brake pads and torque the caliper bolts to manufacturer's specifications (typically 20-25 ft-lbs).
Reinstall the wheel and torque lug nuts to specification (usually 80-100 ft-lbs).
Lower the vehicle back to the ground.
