how to test for sticky calipers?

I'm trying to diagnose a noise that only occurs when I accelerate from a stop. One possibility that has come up has been that the pads are contacting the rotor and then getting "stuck" in that position.

How do I go about testing the caliper to see if this is in fact the case? i.e. how do I test the retraction of the pads?

If they are sticking, what do I need to resolve the situation? If it's a seal, are there kits available?

Thanks!

anyone?

I'm not sure if this is going to be an issue with the parking break lines, or something actually in the caliper. Anyone have any idea how to check the caliper?

other than getting someone to ride with you to help pinpoint what corner the noise is coming from, physically taking everything apart and inspecting the movement of the caliper sliders (where most problems happen for me anyway)... you can see if one corner reads hotter with one of those infared temperature guns or a tire/brake pyrometer

If one is riding weird and dragging/locking up you should be able to take off wheel and inspect the brakes and see that one pad is more warped than the other, and prob. has a lot more brake dust build-up
