Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Inspect Brake Pads

Remove the wheel using a socket set.
Inspect the brake pads for uneven wear; replace if less than 3mm thick.
Check for glazing (shiny surface); if present, replace pads.
Ensure anti-rattle clips are intact and properly fitted.

3. Check Brake Rotors

Use a micrometer to measure rotor thickness; replace if below minimum specification.
Inspect for scoring or grooves; machine or replace rotors if damaged.
Clean rotors with brake cleaner to remove dust and debris.

4. Examine Brake Calipers

Inspect caliper movement; ensure they slide freely on guide pins.
Check for leaks in the caliper; replace seals if necessary.
Lubricate the caliper guide pins with brake lubricant.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Pump the brake pedal several times to reset brake pads to the rotors.
Test drive the vehicle to confirm that the noise has been resolved.
