If there is a significant difference between the drag with the pads in (after pressing and releasing the brake) and with the pads out, suspect old tired piston seals in the calipers.

A gently push should eaily turn the wheel, but dont' expect it to keep spinning more than half a turn or so, if that. You should be able to turn the wheel with you palm flat on the tire without pressing down more than a tiny bit.

There is always some noise from the pads brushing the rotors, they never move very far away, but it should only be a hissing noise that doesn't add any drag to speak of.

If stepping on the brake and then releasing it makes the wheel very hard to turn, one or more pistons is sticking in the bore.
