Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect the Brake Light Switch
  • Locate the brake light switch mounted on the brake pedal assembly.
  • Tools Required: Screwdriver, possibly a socket set.
  • Remove any covers or panels obstructing access to the switch.
  • Check the switch for proper alignment with the pedal; it should activate when the pedal is pressed.
  • If misaligned, adjust the switch position and ensure it clicks when the pedal is pressed. If faulty, replace the switch.
3. Check the Brake Fluid Level
  • Open the hood and locate the brake master cylinder.
  • Inspect the brake fluid level; it should be between the "MIN" and "MAX" marks.
  • If low, top off with the recommended brake fluid type (usually DOT 3 or DOT 4).
  • Reconnect the battery terminal.
4. Test the Brake System
  • Reconnect the negative battery terminal.
  • Start the vehicle and check if the brake light is still illuminated.
  • Test the brake pedal for firmness and proper function.
