Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Tools Required: Jack and jack stands, lug wrench, brake pad thickness gauge, torque wrench, OBD-II scanner.
Safety Warnings: Always wear safety glasses and gloves when handling brake components.

2. Remove Wheel

Loosen the lug nuts with a lug wrench while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Check the thickness of the brake pads. Replace if they are below the manufacturer’s specified minimum thickness (usually around 3mm).
Brake Rotors:
- Inspect the rotors for any scoring, rust, or warping. Replace if necessary.
Brake Hardware:
- Examine shims and clips for wear. Replace any damaged components.

4. Clean and Lubricate

Clean the brake caliper and rotor surfaces using brake cleaner to remove dust and debris.
Apply brake grease to the back of the brake pads and any contact points to reduce noise.

5. Reassemble

Reinstall the brake components, ensuring they are properly aligned.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts to the manufacturer’s specified torque.
