C&V Mechanics - Help with Loose Spring on Altenburger Centerpull Brake

Last night I'm in the garage running cables on a Raleigh Grand Prix that has Altenburger centerpull brakes. First of all, this is the first time I've dealt with center pulls......and I think I hate them. Trying to get the brake cable just the right length, keep tension on the cable, keep tension on the cable carrier, squeeze the brake arms, tighten the bolt...all with two hands! I've got to be doing something wrong.

After a long fight I finally got the rear brake in order and moved to the front. First thing I noticed was that one of the arms was way too loose. The spring has no tension and I can spin it with no trouble. It doesn't look bent and I haven't noticed it doing this before. This being my first time dealing with it, and because this was at 2am, I'm afraid there might be something I'm missing, like the spring not being seated correctly or something. Before I start looking for either a new spring or a different brake, has anybody had this issue before or know if it's a repair or a replace situation?

Own one. Makes adjusting brakes almost effortless. I used them on centerpulls the other day, no problem.
And I've never worked on Altenburgers, but on Weinmann's there are two posts, one on the arm, one on the base, for the spring to press against. Maybe it's not seated on one (or both) of those. If not, it's not the easiest thing to do, but can be done with perseverance and flathead screw driver.

I've thought about that third-hand tool before but have never needed it with dual pivot brakes. Maybe that's the way to go with centerpulls. I did notice the two posts and the spring is getting seated between them, but there's not enough tension on it to do anything. I can just slide it out of position (away from the posts) with one hand. It's like the spring was squeezed too tight, past the point of no return.
