took my passenger hub off yesterday to change a wheel bearing.
took the hub to a garage to get the bearing pushed in. put it all back together and the caliper is rubbing on the disc.

not my picture but the red arrow shows where it's rubbing.
discs aren't warped as it's rubbing all the way round, put new pads in today.
strange thing is, when you look, there is a 2-3mm gap between caliper and the disc, but when driving you can hear the grinding.
and it's definitely the caliper and disc because the disc is marked and the caliper has lost it's paint, just looks clean.
any suggestions as its driving me mad? thanks
