If for some reason you refilled the resevior when the pads were worn/low it would overflow. Otherwise it should be fine.
Sean, I use a 2x4 and whack the rotor to pop it loose. If it's REALLY stuck, sometimes it's possible to wedge the end of a breaker bar between the caliper ear and the rotor and pry. Just make sure the end of the breaker bar clears the fender lip or it will dent the fender from the inside when the rotor lets loose.
