Solution sought for loose Raleigh brake bridge fitting.
On my new to me 1978 Raleigh Competition G.S.,
I'm tempted to just remove this thing. A sleeve goes through the bridge. On the outside, there is a disk that seems firmly attached to the sleeve and on the back or inside, the edge is peened over like a rivet. This eyelet-like thing is loose which makes the brake loose. I'm looking for ideas. I already tried a radiused rear spacer and filed some of the inside peened over part in an attempt to firm up the whole assembly and I'm about to file off a little more.
The black spacer is attached to a loose sleeve.

I would take the brake caliper off, then use a toothbrush with mineral spirits to clean under the "rivet head". Dry that out with a Q-tip, then repeat with alcohol or lacquer thinner. This should remove any grease or wax under that head. Then push some JB Weld under the head, all the way around, cleaning any visible excess with a Q-tip. Let dry overnight, then reassemble. If there is any JB Weld visible, you can paint over it with black model paint.

Oof, I think I know that issue. Best fix is to whack out the peened bits, braze in a proper sized tube, and clean it up. I'm thinking that would be a lot of work to do that. I have a bunch of these in a couple of different sizes:
I'm wondering if you could get your bits on, drill out the bridge for a slip fit, and JB weld one of these in? Do you have someone who could braze it in place for a good permanent fix? Glossy black would be pretty easy to touch up.

Two votes for JB Weld. I’ll give that a shot and ask Santa for a small OA kit. I think I can be nice for 1 more month.

I'm not understanding why adding a washer wouldn't work.

What runs through the brake bridge is a piece like in Gugie's picture. And IT is loose. I can tighten the brake up against the "piece" which results in the brake and piece as a unit being loose as they relate to the bridge.

Should do the job of keeping the brake from shifting position under load.
