Trouble Removing Slider Pin Bolt from Brakes

I am doing a front brake change on our '01 Xterra 4x4. My problem occurs as I turn the bolts with a ratchet, they loosen but do not come off. I don't get it. I keep turning and I feel like they become loose but I can't pull them out or anything. Is there some trick I don't know about or am I just having bad luck?

In Summary

-Tried to change brakes but I can't pull the pin bolts out.

-They just keep turning.

Thanks in advance.

Just pull em out with your fingers.. get a good grip on them with a rag or something non-slip.. pliers may work as well

Thanks.

I figured out the problem though, the nut that it is attached to was rolling with the pin and it would not loosen. Just keep spinning.
