Can someone please help me ASAP! I'm trying to paint the brake calipers to my X3 and for some strange reason I am not able to take off the wheel. Is there some sort of ritual that is needed to take the wheels off...other then removing the bolts? It's a good thing I found this out in my garage and not on the road.

Please help!!!!
