Rear brake rewind screw

Rear brake rewind screw
Putting new brake pads in and winding the allen screw out to retract the piston. It worked on the left caliper but seized on the right one. When I forced it it stripped something (I think a little toothed wheel a the bottom of the hole - hard to see). Anyway piston wasn't looking great so I took to local motor factors and PX for a rebuilt caliper. Only problem is the new one did exactly the same. I've taken it back and will get it replaced for free.
My question is:
Am I doing something wrong?
Are these adjusters made of cheese and a well documented problem?
Or am I just having bad luck?!

cheese indeed. If you put a good fitting allen key in and put slight sideways pressure on the key while pulling it out in a downward direction, the key will grip the stripped piece and pull it right out. It's a little gear looking gizmo made of hardened sour milk. The "teeth" on the gear will fail if you look at them wrong. Once you've adjusted the caliper so that it wont back out anymore, you may attempt to compress the piston with *careful* pressure and you might get a couple more millimeters out of it. If you attempt to compress the caliper the way my dad taught me: "Put a C-Clamp on there and crank the **** out of it" you'll likely damage the caliper, but I'm pretty sure you are already aware of that.
Unfortunately, even if you pull out the allen key gear gizmo made of used french fry grease, there's not much you can really do with it. You can't buy a "cog of swiss cheese" from NAPA.

yeah, I've swapped a number of stripped ones out after too much force was put on them. It's just another thing to take out and lubricate along with your slider pins. With a little sideways pressure on the allen wrench as described above, it should slip right out.
