Working on my Empi disc brake kit. I installed new brake lines. The one on the right was bad. Changed both. A bitch. Worked on the left side first. I didn't remember the rotor hard to get on but I like to have never got it off. I knocked it off with my dead blow hammer. I think I put grease on the splines when I put it on but it was hard to get off. I was wondering if anyone knows how to loosen it up where it goes on easier. I figure it should slide on and off pretty easy. Any suggestions? Thanks
