Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Use a socket set to loosen the lug nuts on the wheel where the noise is noticed.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Examine the brake pads for wear. If they are less than 1/8 inch thick, they should be replaced.
Check the rotors for any grooves or excessive wear. If damaged, they need resurfacing or replacement.
Inspect the brake calipers for proper operation and ensure they are not stuck.

4. Replace Brake Pads (if necessary)

Remove the caliper by unscrewing the caliper bolts using the socket set.
Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Apply anti-squeal lubricant to the back of the new brake pads.
Install the new brake pads into the caliper bracket.

5. Reassemble the Brake Components

Reinstall the caliper over the new brake pads and torque the caliper bolts to the manufacturer’s specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern.

6. Test the Brakes

Pump the brake pedal to ensure the pads seat properly against the rotor.
Take the vehicle for a test drive to confirm the noise has been resolved.
