Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang on the brake line).
Remove the old brake pads and inspect them for wear. If they are worn down to 3mm or less, replace them.
Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the thickness of the rotors with a micrometer. If they are below the minimum thickness, replace them.
If replacing, remove the rotor by removing the retaining screws or bolts.
Clean the hub surface and install the new rotor, ensuring it is properly seated.

5. Reassemble Brake Components

Reattach the caliper over the new pads and tighten the caliper bolts to the manufacturer’s specified torque (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands and remove the jack.
Tighten the lug nuts to the manufacturer’s specified torque (usually 80-100 ft-lbs in a star pattern).
Reconnect the negative battery terminal.
