Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the ignition is off.
  • Wear safety gloves and goggles for protection.
2. Raise the Vehicle
  • Use a jack to lift the vehicle securely and place jack stands under the appropriate jack points.
  • Remove the wheel using a socket set.
3. Inspect and Replace Brake Components
  • Inspect Brake Pads and Rotors:
    • Check the thickness of the brake pads; replace if they are worn below the manufacturer's specified minimum thickness.
    • Examine the brake rotors for scoring or warping; replace if necessary.
  • Replace Brake Pads:
    • Remove the caliper bolts and slide the caliper off the rotor.
    • Remove the old brake pads and install new ones, ensuring they are properly aligned.
  • Replace Brake Rotors (if necessary):
    • Remove the rotor by unscrewing any retaining screws.
    • Install the new rotor and secure it with the screws.
4. Inspect Wheel Bearings
  • Check the wheel bearing for any play by wiggling the wheel.
  • If there is excessive play, remove the hub assembly to access the bearings.
  • Replace any worn or damaged wheel bearings with new ones.
5. Reassemble and Lower the Vehicle
  • Reattach the brake caliper and tighten the caliper bolts to the manufacturer’s torque specifications.
  • Reinstall the wheel and hand-tighten the lug nuts.
  • Lower the vehicle from the jack stands and torque the lug nuts to the specified value.
