Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, brake cleaner, safety glasses, gloves.
Safety Warnings: Ensure the vehicle is on a flat surface. Use wheel chocks to prevent rolling. Disconnect the battery if working on electronic brake components.

2. Raise the Vehicle

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

3. Remove the Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Remove the caliper bolts with the socket set.
Carefully slide the caliper off the rotor and support it without straining the brake line.
Inspect the brake pads for wear. If they are below the minimum thickness (usually 3mm), replace them.
To replace, slide new brake pads into the caliper bracket.

5. Inspect and Replace Brake Rotors (if needed)

Check the rotor surfaces for scoring or grooves. Measure thickness to ensure they are within specifications.
If worn, remove the rotor by unscrewing the retaining screws (if applicable) and slide it off the hub.
Install new rotors, ensuring they are clean and free of oil.

6. Reassemble Components

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to the specified torque (usually around 25-30 Nm, but check the service manual).
Reinstall the wheel and lug nuts, tightening to the manufacturer's specified torque.

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
