Anyway to test calipers off of a car??

[spooled_u]

About 5 months ago I purchased dual piston 93+ awd calipers from Gary (MitsuGraveyard), and since then I'd blown my motor and sold my car since then. The calipers look really dirty and I'm sure they need re-lubing on all the pins and guides, but I'm wondering if theres anyway to tell if the pistons are seized up. I really don't want to go through the trouble of doing the swap and putting them on my car and then realizing that they don't work. They've been sittin in my basement for almost half a year.

Suggestions anyone??

Compressed air will pop the piston out of the caliper. If it doesn't, then you could have problems.

How much are reman calipers? If you have the core, calipers can be really cheap. I bought 2 fronts for $26 once.
