Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
  • Wear safety gloves and goggles for protection.
2. Raise Vehicle
  • Use a jack to lift the vehicle and place it securely on jack stands.
  • Remove the wheels to access the braking components.
3. Inspect and Replace Brake Pads
  • Inspect: Check the thickness of the brake pads; if they are less than 3mm, they need replacement.
  • Remove: Unbolt the caliper using a socket set and slide it off the rotor.
  • Replace: Remove the old brake pads from the caliper bracket. Install the new pads, ensuring they are correctly positioned and seated.
4. Inspect and Replace Brake Rotors
  • Inspect: Check the brake rotor surface for grooves or warping. Measure the rotor thickness with a micrometer.
  • Replace: If necessary, unbolt the rotor from the hub and replace it with a new one, ensuring it is torqued to the manufacturer specifications (typically around 80-100 lb-ft).
5. Reassemble
  • Reinstall the caliper over the new brake pads and rotor.
  • Tighten caliper bolts to the manufacturer's specified torque.
  • Reinstall the wheels and lower the vehicle back to the ground.
6. Final Checks
  • Pump the brake pedal several times to seat the new pads.
  • Check brake fluid level and top off if necessary.
  • Dispose of old brake components properly.
