Re: HHH > STINGER
If there isn't a spring tension screw then the older ones may have a bunch of holes at the base of the lever post, on the fork. Try mounting the brake arm with it's little metal direct spring into a hole. They progressively will had more tension on the wire/spring as the metal wears out over the life of the bike. This system is usually on older V-brakes.
It sounds like you need more spring tension.
or it is the levers.
Direct-pull cantilevers have double the mechanical advantage compared with traditional brakes, so they require special brake levers. Direct-pull brake levers pull the cable twice as far, half as hard. The lower mechanical advantage of the lever compensates for the higher M.A. of the cantilever. It is not generally safe to mix and match levers/cables between direct pull and other types for this reason.
* Conventional brake levers used with direct-pull cantilevers will usually not pull enough cable to stop in wet conditions without bottoming out against the handlebars. In dry conditions, they either won't work, or will grab too suddenly.
* Direct-pull brake levers used with any other type of brakes will feel nice and solid when you squeeze them, but due to their lower mechanical advantage you'll need to squeeze twice as hard to stop as you should, so unless you are a lightweight rider with gorilla-like paws, this combination isn't safe either.
To make a brake lever with low enough mechanical advantage for direct-pull cantlevers, the cable must run twice as far from the lever's pivot point.
Hopefully you get it all sorted out. V-brakes usually require a lot of fidgeting to get just right.
