Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Use a lug wrench to loosen lug nuts while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect the brake pads for wear; replace if they are less than 3mm thick.
Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the brake pads, supporting it with a bungee cord or similar device to avoid straining the brake line.
Remove the old brake pads and replace them with new ones, ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for any visible damage or warping. Use a micrometer to measure rotor thickness.
If replacement is necessary, remove the rotor by unscrewing the retaining screws or using a hammer to tap it off if it's stuck.
Install the new rotor and ensure it is seated flat against the hub.

5. Reassemble and Reattach Wheel

Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer's torque specifications (typically around 25-35 ft-lbs).
Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the proper torque specification (usually 80-100 ft-lbs).
