Changed brake shoes on my Brompton... older bike, CLB made single pivot calipers,
Kool Stop Salmon Continental molded shoes, a bit different from the shoe/padholder that CLB designed due to a threaded boss on the pad holder.
But cutting a strip out of an aluminum pie pan, folding it over, and wrapping it around the molded in stud on the KS pad, worked fine, just needed to get the stud in the center of the slot in the brake arm . and a bit wider flatwasher..
Kool Stop pads are a good upgrade for any rim brake .
