Depending on how long it sat and where it came from, the calipers "could be" seizing. My VX only gets about 3k miles a year so it sits in the garage a lot. I'm also in the mid atlantic, which gets it's fair share of road salts every winter. Due to the fact that it sits.... alone.... in a dark garage (queue violin), and has ugly elements to deal with on rare occasions, I find myself replacing calipers probably every 3-4 years. The signs they are going are, squeaking, failure to release from breaking (just sits at idle in drive when break is released), and slight grind when in motion (pads and rotors fighting to see who is best!). Were I to drive it more, it would be much less an issue since they would flex off most of the gunk, but I am a bad, bad owner.
