Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and suspend it using a wire hanger to avoid straining the brake line.
Remove the old brake pads and inspect for wear. Replace if they are below the manufacturer’s specifications, typically 3 mm or less.
Apply brake grease to the back of the new pads to prevent squeaking.
Install the new brake pads.

4. Check and Replace Brake Rotors (if necessary)

Inspect the rotor surface for grooves or warping.
If damaged, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new rotors, ensuring they are clean and free of contaminants.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads and torque the caliper bolts to specifications (typically around 25-30 Nm, but refer to the service manual for specifics).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (usually around 90-110 Nm).

6. Final Inspection

Check brake fluid level and top off if necessary.
Pump the brake pedal to ensure proper engagement of the new pads.
Conduct a test drive at low speeds to confirm the noise has been resolved.
