Solution

1. Preparation

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

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which brakes are making noise.
Secure the vehicle with jack stands to prevent it from falling.

3. Remove Wheel

Use a lug wrench to loosen and remove the wheel nuts.
Take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Inspection: Check the brake pads for thickness. If they are less than 3mm, replace them.
Replacement:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it with a hanger or bungee cord to avoid straining the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated.

5. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for any scoring or warping. If they are damaged:
- Remove the caliper bracket bolts.
- Slide the caliper bracket off.
- Remove the rotor by pulling it straight off the hub.
- Install new rotors, ensuring they are clean and free of grease.

6. Reassemble the Brake System

Reattach the caliper bracket and caliper, tightening the bolts to the manufacturer's specified torque value (usually around 25-35 ft-lbs, check your service manual).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle back to the ground using the hydraulic jack.
Tighten the lug nuts to the manufacturer's specified torque (typically 75-90 ft-lbs).

8. Test the Brakes

Before driving, pump the brake pedal several times to ensure proper seating of the brake pads.
Test drive the vehicle to verify the noise has been resolved.
