Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a flat surface and engage the parking brake.
  • Use wheel chocks to prevent movement.
2. Lift the Vehicle
  • Use a jack to lift the front or rear of the vehicle as needed.
  • Secure with jack stands for safety.
3. Remove Wheel
  • Use a socket set to remove the lug nuts and take off the wheel.
4. Inspect and Replace Brake Pads
  • Inspect Pads:
    • Remove the caliper bolts with a socket wrench.
    • Carefully lift the caliper off the rotor without stretching the brake line.
    • Check the brake pads for thickness and wear. Replace if less than 3mm thick.
  • Replace Pads:
    • Remove the old pads from the caliper bracket.
    • Install new brake pads ensuring they seat properly.
    • Apply brake grease to the backing plates of the new pads to prevent squealing.
5. Inspect and Replace Brake Rotors (if necessary)
  • Inspect Rotors:
    • Check for scoring or grooves. Replace if damaged or if thickness is below manufacturer specifications.
  • Replace Rotors:
    • Remove the caliper bracket by unscrewing its mounting bolts.
    • Slide the rotor off the hub.
    • Clean the hub surface and install the new rotor.
    • Reinstall the caliper bracket.
6. Reassemble and Lower Vehicle
  • Reinstall the caliper over the new pads.
  • Tighten caliper bolts to the manufacturer's torque specification (typically 25-35 lb-ft).
  • Reattach the wheel and secure it with lug nuts. Tighten to the specified torque (usually 85-100 lb-ft).
  • Lower the vehicle and remove wheel chocks.
