Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a hydraulic floor jack to lift the front or rear of the vehicle, depending on which brakes are noisy.
Secure the vehicle on jack stands for safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Store lug nuts in a safe place.

4. Inspect and Replace Brake Pads

Remove the caliper by loosening the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor, ensuring not to damage the brake line.
Remove the old brake pads and inspect them for wear. If they are worn down to less than 3mm, replace them.
Install new brake pads, ensuring they are properly aligned and seated.

5. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or warping; if damaged, remove the rotor by unscrewing the retaining screws.
Install a new rotor, ensuring it is clean and free of debris.

6. Reassemble Components

Reattach the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque (typically around 25-35 Nm, but verify with the 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 (usually around 90-120 Nm).
