Does the bolt pinching the brake cable on dia compe side pull back out?

I'm having trouble replacing the brake cable on my old bike. It is an early 80s with dia compe side pull. I can't seem to thread the cable through the hole in the bolt which pinches the cable to the brake. Sorry I can't attach a picture right now but I will try later.

The bolt doesn't seem to back off enough to easily access the hole. It's quite a tight fit and I was wondering if maybe there's something wrong with it. This is the first time I've tried replacing the cable. Any cable, really. Is the bolt supposed to back out completely or was it designed to only back out just enough to make it difficult to push through a new cable? Or is the brake so old it's somehow deformed in that part that it won't make it easy to thread the cable?

Thanks

typically they will back out completely if you smack it with something. i think what happens is when the cable gets clamped down hard, the alloy on the caliper side of the clamp gets a little bit marred around the bolt, thus making it stick in there. newer or better condition brakes it will just back out and fall out all the way.

short answer: yes, tap it out.

Thanks. This is a big help. I will try to tap it out. I've been wanting to fix this brake for a couple of weeks now. Bye.

Sometimes you DO need to reach for a bigger hammer

The trick is knowing when

Yep, the design. Nasty. Brake pinch bolts are so much better these days, particularly the more recent high-end stuff. They clamp the cable real good without making a mess.
