I dunno from what I read. Other than a damaged fork, it "appears" that there is a definite solution, or at least a most likely one... the brake cable hanger is too far way from the brake. The solution seems to be changing to a fork crown hanger or go to linear brakes. Also the '96 Outpost fork does not look that stout.

My vote, when you are able, it to go with linear brakes. I have a couple of mountain bikes and one has cantilever brakes, so I'm not against using them. Flat bar linear brake levers are cheap and easy to find.

Since you are one the road, you may want to shorten the brake pads, per the info in the attached link in a earlier post. Regardless, I would think you would want to refrain from too much downhill speed until you can fix it.
