Solution
1. Preparation
  • Gather the necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the parking brake is engaged.
  • Use wheel chocks to prevent rolling.
2. Remove Wheel
  • Using a lug wrench, loosen the lug nuts slightly while the wheel is still on the ground.
  • Raise the vehicle using a jack and secure it on jack stands.
  • Remove the lug nuts and take off the wheel.
3. Inspect and Replace Brake Components
  • Brake Rotors:
    • Use a dial indicator to check rotor runout. If it exceeds manufacturer specifications, replace the rotor.
    • If replacing, remove the caliper bracket bolts and slide off the caliper. Then, remove the rotors.
  • Brake Pads:
    • Inspect the brake pads for wear. If they are below the minimum thickness, replace them.
    • Remove the old pads and install new ones according to the manufacturer’s specifications.
4. Reassemble Components
  • Reattach the rotor (if replaced) and caliper. Ensure bolts are tightened to the specified torque (typically 25-35 ft-lbs for caliper bolts).
  • Reinstall the wheel and hand-tighten the lug nuts.
  • Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually around 80-100 ft-lbs).
5. Test Brake System
  • Pump the brake pedal to ensure proper brake pad seating.
  • Conduct a test drive at low speeds to ensure vibrations have been eliminated.
