In older vehicles that have had the cable adjusted multiple times, the cable can stretch. So if you have adjusted to the max and still cant get the brake to hold you may need to replace the cable. ( Check the pads first tho because I would suspect they are worn also).
Another reason would be if you see any frayed or broken strands in the cable.
The last would be if you have a hard time setting or releasing the brake. Then you can look at the cables and verify that there is a buildup of material inside the cable which prevents it from moving inside the sheath. You can usually disconnect it at both ends and push or pull it thru the sheath while it is still in place. If it moves freely then no need to replace it.

If it is the cable that is loose yes. Underneath the vehical there should be a steel cable runnig from the brake handle to the rear of the van. this single cable attaches to another cable -< there should be a bolt adjuster at the connection. If the cable itself is broken replace cable. (nanner)
Cable is rusted, bent, or hanging for some reason. Could also be the parking brake needs adjustment. The brake is not fully releasing.
Adjuster should be under the vehicle at the junction of the 3 cables Set parking brake to "3" clicks and tighten cable - vehicle should hold at this point
Check the emergancy brake cable- as it starts to wear, it stretches & leaves slack in the cable. There should be an adjustment to remove this slack. The tension in the cable pulls the lever to not make the switch for the brake light come on.
