Just did my second CX5 front brake job. Here's a tip for removing rotors should they be rusted on like mine were...again, despite having disassembling the assembly and coated them on the inside with anti-seize after I bought it new. On the hub of the rotor you'll see a threaded hole, should be for a 7mm bolt to fit in it. Most likely the bolt with strip through the rusted threads, so I have an 8mm bolt that I just force into the hole, it usually does the trick and pops off the rotor, make sure you douse the hub with lubricant. It always seems to be the driver's side that gets rusted on for some reason.
