Brakes seem to be holding on too tightly

Hi.
My car pulls slightly to the right under heavy braking. I checked the front hubs with the wheels off and found that after applying the brakes and releasing the right hand hub pads are stopping the hub spinning on at all when I try to set it spinning by hand, whereas the left hand one spins on about half a turn. As the car is jacked up there's no end float movement to push the pads out, so it's only the spring back of the seals that would release the pad grip. I wondered if what I'm seeing is normal. The car does roll freely when on the ground.
I've taken the pads out to make sure they're not binding. With no pads in both front hubs spin freely..
If the piston seals are too hard, or in the wrong way round, this is what I would expect to see. I don't want to start pulling the front calipers apart, but will if there's really a problem. How freely do others hubs spin?
Thanks.
