Thanks for the link to JB. I'm sure something will affix them solid. Primary concerns for brake application is shear and heat under extreme conditions.
For pads: Having trouble finding the page link and technical specs of this early formula. The compound is one of the best I've experienced and wear like none other. If I can't find the rubber compound, the alternative is somehow attaching a metal back holder for other brand slide in pad cartridge. Has anyone attempted a conversion? Epoxy or machined plate? I do have some slim aluminum channel stock and was thinking of a peg in the center + JB metal epoxy. The channel stock would be cut to pad length and tab locked at one end.
This grouping happened to be included with a brake set I just acquired. Although kind of a shame in that it looks like someone intentionally removed the rubber compound. All things considered were freebies and worthwhile experimenting with. Ultimately would like to use for a vintage gravel bike build.
