As I noted, lots more to do, compared to installing conventional caliper brakes......
BTW, the original Campy pad holders have have small Allen grub screws that can push out the ends of the pad slightly, by means of a flex plate between the pad and holder, to provide a bit of toe-in with the pads and avoid the screechies, so it will be a good reason to retain them, as much as possible and just update the pads with more modern compound Kool Stops.....
An additional note, one has to regularly open and clean out the caliper casing, as these calipers tend to build up with a lot of road grit and debris thrown up by the tires that get through the seams of the casing. You do not want that stuff mucking up the mechanism of the calipers and cause wear ar all the pivots and joints in it....
