It is caused by the brake pads shifting backwards in the front calipers as they are worn. I have the same problem in my '83 turbo as well. The only way I have heard to fix it is to try to somehow tighten up the U-clip that holds the pads in the calipers, either by welding some metal into the grooves somehow, or to just find some rebuilt calipers that aren't worn. I never have done anything about it myself, it is not a critical problem with these cars. It's a 'quirk', it's Saab character. Gotta love those 8-valves though! Keep 'em on the road! -SAABhuman
