Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Brake Fluid Level

Locate the brake fluid reservoir, typically found near the back of the engine bay.
Remove the cap and check the fluid level against the markings on the reservoir.
If low, top off with the recommended brake fluid (DOT 3 or DOT 4).

3. Inspect Parking Brake Switch

Locate the parking brake switch, usually found near the parking brake lever.
Disconnect the electrical connector from the switch.
Use a multimeter to check for continuity when the lever is engaged and disengaged.
If the switch is faulty, replace it with a new one.

4. Examine Parking Brake Cables

Inspect the cables for fraying, kinks, or other signs of wear.
Ensure the cables are properly connected at both the lever and the rear brakes.
If damaged, replace the cables.

5. Test Parking Brake Operation

Reconnect the negative battery terminal.
Engage and release the parking brake several times to ensure proper function.
Check the dashboard for the parking brake light status.

6. Final Checks

After repairs, verify brake functionality by testing the vehicle on an incline to ensure the parking brake holds properly.
