Solution
1. Preparation
  • Tools Required: Wrench set, brake fluid, OBD-II scanner, multimeter, socket set, jack and jack stands.
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Disconnect the battery to avoid any electrical issues.
2. Check and Replenish Brake Fluid
  • Locate the brake master cylinder reservoir.
  • Remove the cap and check the fluid level.
  • If low, top up with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
  • Replace the cap securely.
3. Inspect and Replace Brake Pads and Rotors (if necessary)
  • Tools Required: Socket set, torque wrench.
  • Lift the vehicle using a jack and secure it with jack stands.
  • Remove the wheel using a socket set.
  • Inspect brake pads for thickness (replace if worn below 3mm) and check rotors for scoring or warping.
  • If replacement is needed:
    1. Remove caliper bolts and take off the caliper.
    2. Replace brake pads and ensure they are properly seated.
    3. If rotors are worn, remove the rotor and replace with a new one, ensuring proper alignment.
    4. Reinstall the caliper and torque bolts to the manufacturer's specifications.
4. Check Brake Light Switch
  • Locate the brake light switch, usually near the brake pedal.
  • Use a multimeter to check for continuity when the pedal is pressed.
  • If defective, disconnect the switch and replace it with a new one, ensuring it is properly adjusted.
5. Reconnect Battery and Test
  • Reconnect the battery terminals securely.
  • Start the vehicle and check if the brake warning light is still illuminated.
