Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect and Clean Parking Brake Mechanism

Tools Required: Socket set, brake cleaner, wire brush
Remove the rear wheels to access the parking brake components.
Clean the parking brake shoes and drum or rotor surfaces using brake cleaner and a wire brush to remove any debris or rust buildup.
Visually inspect the components for any signs of damage or excessive wear.

3. Adjust Parking Brake Cable

Tools Required: Wrench set, pliers
Locate the parking brake adjustment mechanism, usually found under the vehicle near the rear axle.
Use a wrench to loosen the adjustment nut and pull the cable to release tension.
Adjust the cable until there is slight resistance when the parking brake lever is pulled.
Re-tighten the adjustment nut securely.

4. Test and Reassemble

Reinstall the rear wheels and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
Test the parking brake by engaging and releasing it multiple times to ensure it operates smoothly.
If the brake releases properly, reassemble any components removed during the inspection.
