You were the one who brought up the issue of using a hammer and punch,
with your categorical statement that "I don't believe it was ever
appropriate."

The subject of this thread was centering a modern high quality Shimano
brake, not steel caliper Raleigh brakes of decades ago. Even those
brakes recognized the problem and made spring bosses pressed onto
knurled center bolts that were pressed in place to assist adjusting
brake position.

That's not correct. The "spring bosses" were either threaded onto the
center bolts (for the cheaper models) or were a slip fit over the center
bolts. The part involved was a single casting, nothing knurled, no way
to rotate the front vs the back.

Let's leave the hammer and punch in the historic bin.
There is no place for them on any recent aluminum alloy brake caliper.

That's true.
