Brake Caliper Slider Pins

[BennyHill]

I am rebuilding the rear brake calipers and have noticed that one of the slider pins on each carrier has a small amount of free play / rock. The other slider pins do not have the same free play and move smoothly without any rock. I have tried swapping the pins over, but the problem is the same, so I know there is a diference in the bore of the hole in the carrier.

Is this normal, or should both pins be rock free?
