Solution

1. Preparation

Gather necessary tools and safety equipment.
Park the vehicle on a flat surface and engage the parking brake.
Loosen the lug nuts slightly before lifting the vehicle.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands to ensure safety.

3. Remove Wheel

Fully remove the lug nuts and take off the wheel to access the brake assembly.
Tools required: Lug wrench, jack, jack stands.

4. Inspect Brake Components

Check the brake pads for wear; replace if they are below the manufacturer's recommended thickness (usually 3mm).
Examine the brake rotors for scoring, rust, or uneven wear; consider resurfacing or replacing if necessary.
Tools required: Caliper tool to measure pad thickness.

5. Clean and Lubricate

Clean the brake rotors with brake cleaner to remove any debris or contaminants.
Apply brake grease to the back of the brake pads and the caliper contact points to reduce noise.
Tools required: Brake cleaner, brake grease.

6. Reassemble

Reinstall the brake components, ensuring all bolts are tightened to the manufacturer's specifications.
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (usually around 80-100 ft-lbs).
