Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and securely raise it using a jack and jack stands.
Wear safety goggles and gloves.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Carefully remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Pads: Check the thickness of the brake pads. If they are less than 1/8 inch thick or worn unevenly, they need replacement.
Remove Old Pads: Use a socket set to remove the caliper bolts. Slide the caliper off the rotor and hang it using a bungee cord (do not let it dangle by the brake line).
Install New Pads: Remove the old pads and install new pads in the caliper bracket. Ensure they are seated correctly.

4. Inspect and Resurface/Replace Rotors

Check Rotor Condition: Measure rotor thickness with a caliper. If below minimum specifications or if there are deep grooves, replace or resurface the rotors.
Remove Rotors: If replacing, remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
Install New Rotors: Place the new rotor onto the hub and secure it.

5. Reassemble and Test

Reinstall Caliper: Slide the caliper back over the new pads and secure it with bolts to the specified torque (usually around 20-25 ft-lbs).
Reattach Wheel: Place the wheel back on and hand-tighten the lug nuts.
Lower Vehicle: Carefully lower the vehicle to the ground and then fully tighten the lug nuts in a star pattern to the manufacturer’s torque specification (typically around 80-100 ft-lbs).
