Assuming this is a DRW, unbolt the extension and remove it. Remove the caliper. Remove the caliper support and I think the rotor just pops off, may take a little persuasion.
The rears are a little different because the rotors bolt in from the back side so you have to pull the hub. Don't think the fornts are like that thouhg but all I have is an SRW and they don't bolt on.
