Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the vehicle's battery to ensure safety.

2. Inspect Brake Pads

Remove the wheel using a jack and lug wrench.
Inspect the brake pads for thickness; replace if below the manufacturer-recommended minimum thickness (typically 3mm).
Check for uneven wear and any signs of cracking or damage.

3. Inspect Brake Rotors

Remove the brake caliper using a socket set.
Inspect the rotor surface for any grooves, scoring, or excessive rust.
Measure rotor thickness with a caliper to ensure it meets specifications; replace if below the minimum thickness.

4. Clean and Lubricate Components

Clean the brake components with brake cleaner to remove dust and debris.
Apply brake grease to the back of the brake pads and the caliper sliding pins to prevent noise.
Ensure that the brake caliper slides freely.

5. Reassemble and Test

Reinstall the brake caliper and torque bolts to manufacturer specifications (typically around 30 ft-lbs).
Reinstall the wheel and torque lug nuts to specifications (usually 80-100 ft-lbs).
Reconnect the battery and conduct a test drive to assess brake sound and performance.
