The 30 year old one that I misplaced didn't transmit any torque last time I
used it. It was just a big convenient handle for me to twist while banging
on the screw. As I recall, I never used it against any bearings.

The scheme expressed on the DIY web was that the old one would make it's
way out, and the new one would have to have a portion of the head ground
off to fit back in. Punching the stud was a worthless endeavor, and I knew
it. My DIY was a lot more worthy in the past. I have rebuilt piston and
rotary motors, and did some impressive parking lot repairs, but that was
long ago, before I found it more convenient to have someone else do the
work for me.
Disk pads is about the only thing I've done in several years, because the
price is so outrageous compared to the amount of labor.

That sounds like a recording from the shop. ;-)
I'm going to take the knuckle off and down to him for pressing, and replace
the bearing and four studs. If I do this one day on the other side, I
don't think I'll even bother to take those two screws out to get the disk
off. I'll just haul it down to him as part of the knuckle.
