1. Preparation

Gather tools and components:

Locate the parking brake cable under the vehicle.
Check for any frays or damage; replace if necessary.
If the cable appears intact, adjust the cable tension:
1. Locate the adjustment nut at the rear of the cable.
2. Use a wrench to adjust the nut, ensuring there’s enough slack for the brake to release fully.
3. Test the functionality by pulling the parking brake lever and releasing it.

3. Replace the Brake Switch (if faulty)

Locate the brake switch, usually mounted near the parking brake lever.
Remove the connector by pressing the tab and pulling it off.
