My brakes ARE Shimano, but they do not use pad inserts. The only way to change pads on these (BR 6403) is to replace the entire shoe. Unfortunately, the only compatible shoe available anymore is the BR 6403. They work ok in dry weather, but they are taller and shorter than modern pads, so they rub past the brake track, and they suck in the rain.

Here is another suggestion that will work. Let's say the caliper hole is 3mm for the current pads. Measure the new pads to determine the diameter of the stud - say 4mm. Then use a 4mm drill bit to carefully enlarge the hole to accept the new pads.
That would probably work, and there's little chance of "whoops, I drilled too much" with that. Thanks.
