Nellified

I have a 2002 IS300 and I took my caliper off and tried to pull the rotor off and it would not budge. It looked like it requires a pulling tool to get it off so I didnt hit on it or anything. I cannot find any info on taking the rotors off so are they just rusted on or do I need a special tool.

I was listening to cd in my 1993 es 300 Pineer 6 disk changer ans when I changed disks, it tried to read and it said ERR. I tried to put a lens cleaner disk in the changer, but it did not help. I cannot find a replacement and there are some on eBay but they are too hard to get. Everytime i put a cd in the changer it says err and will not play. I need help.
