I removed my calipers today and dropped my front tire out of my 99 Low rider and upon the reinstall I went to spin the tire and the pads scratch the rotor a bit. I dont remember if they rubbed before i undid it all or not. is there suppose to be a little bit of drag on the rotors from the pads or did they compress a bit when removed? The pads are almost new so I know those dont need replacing. Thanks for the help!
