I need some help removing the front rotors on my 03 X. I got the caliper off and tied it off to the side. I have the rotor screws off, so the rotor is loose. But I can't get the caliper *holder* (is that what you call it) off. That seems to be in the way removing the rotor. It has two 19mm bolts that I just can't get off! I've soaked it with WD40 to no avail. Anybody got any advice for me? ...apart from putting it all back together and bringing it to a shop...
