Solution
1. Preparation
  • Tools Required: Jack and jack stands, lug wrench, flashlight, brake pad gauge.
  • Ensure the vehicle is parked on a level surface and engage the parking brake.
  • Wear safety gloves and goggles for protection.
2. Lift the Vehicle
  • Loosen the lug nuts on the wheels before lifting.
  • Use the jack to lift the vehicle and secure it with jack stands.
  • Remove the wheels using the lug wrench.
3. Inspect Brake Pads
  • Locate the brake caliper and remove it by unscrewing the caliper bolts.
  • Carefully slide the caliper off the brake pads.
  • Measure the thickness of the brake pads using a brake pad gauge.
    • If the thickness is less than 3mm, replacement is necessary.
  • Inspect the pads for any uneven wear or cracking.
4. Inspect Brake Rotors
  • Check the rotor surface for grooves, warping, or scoring.
  • Use a micrometer to measure rotor thickness; if below manufacturer's specifications, replacement is required.
  • If the rotors are within specs but have minor issues, they may be machined to restore surface.
5. Reassemble Components
  • If brake pads or rotors are replaced, install the new components.
  • Reattach the brake caliper and secure it with bolts to the specified torque.
  • Reinstall the wheel and hand-tighten the lug nuts.
6. Lower the Vehicle
  • Carefully lower the vehicle back to the ground using the jack.
  • Tighten the lug nuts to the specified torque rating (typically 80-100 ft-lbs).
