Understood. Was looking at a car the other day for potential purchase. Owner said the parking brake needed adjustment. I tried the brake out and found that it seemed to hold OK. The lever's action seemed normal. The only thing I found that might be an issue is that the release button in the handle seems recessed too far and is tricky to push in. Seems like its more an issue with the button return spring in the handle than an actual parking brake cable adjustment or replacement.
thanks.
