Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Disconnect the battery cable to eliminate electrical hazards.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set and carefully lift the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
Compare the thickness of new pads to the old ones to ensure they meet specifications.
Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotor surface for grooves or excessive wear. If damaged, replace the rotor.
Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Clean the hub surface and install the new rotor, ensuring it is properly seated.

5. Reassemble Components

Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications (usually around 20-30 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the recommended specification (typically 80-100 ft-lbs).
