IIRC, there is a bit of a bump on the outside of the castings of all the 
calipers, just outside of where the center of the piston would be. For the OE 
style calipers, that would be where the compensating pin is anchored; the late 
calipers don't have this pin, but I think they just left the casting as is. Is 
this what you mean, or are yours even more prominent?

I'm not sure I'm remembering this correctly, in spite of the fact that I spent 
yesterday afternoon taking apart about 6 calipers. My new caliper pump worked 
great; I didn't have the slightest bit of trouble getting even the worst of 
them apart. There were a couple that I had to press down with nearly my full 
weight, though.

I figure that with this new pump I can put about 1500 psi behind one of those 
pistons. That's about 15 times what I used to be able to do. I used to spend 
hours getting a medium stuck one apart; now it takes about 10 minutes, which 
includes the fiddling time that it takes to plug the first piston opening so I 
can pump out the second piston.

I was probably close to 1000 psi with some of these pistons. At 1000 psi, there 
would be about 2150 pounds of force pushing that piston out. No wonder these 
were hard for me to do before.  ;-p

I'm gonna have a few calipers ready to go here in a couple of days, but I'm 
still looking for good used early calipers. My experience yesterday seems to 
indicate that old ones that have been stored a long time might actually be in 
fairly decent shape once I get them all apart.

So, yes, Keith, I'm interested in that stash you have. I wonder how much that 
box will weight....
