2006 sierra brake rotor
 

Ok, I have taken rotors off of lots of trucks, however, I cannot get the front rotor off of my 2006 sierra. Am I missing something or do I just need a bigger sludge hammer. I am replacing it, so it does not matter if I ruin it.

I am soaking it with sea foam and I am hitting it with a sludge, no luck yet.

any ideas?

You may need to put some heat. I had that same problem but the hammer eventually won.
