Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative terminal of the battery to prevent electrical issues.

2. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" markers.
- If low, top off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Reinstall the cap securely.

3. Inspect and Adjust Brake Light Switch

Locate the brake light switch under the dashboard, near the brake pedal.
Visually inspect the switch for any damage or misalignment.
If necessary, adjust the switch by turning the adjustment screw to ensure it activates when the brake pedal is pressed.
If the switch is defective, proceed to replace it:
- Disconnect the electrical connector.
- Remove the switch from its mounting location.
- Install the new switch and reconnect the electrical connector.

4. Verify Emergency Brake Lever Position

Ensure the emergency brake lever is fully released.
If the lever is stuck, lubricate the pivot points with appropriate lubricant.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the vehicle and check if the emergency brake light is still illuminated.
Test the functionality of the brake system by pressing the brake pedal.
