I think you need to grease the back of the pads and just swap it.
I recommend PosiQuiet, the mother of all StopTechs..which is extremely popular right now across all car forums,
highly underrated. I have some waiting to be installed
I'm only at like 36k miles though, but my brakes are squeaking..and they don't brake as good as they used to for sure.
I got my rotors re-machined at the dealer as per their TSB saying they're susceptible to warping, and after a trip to
the mountains where it was snowing and coming down the mountain fast in freezing weather...they warped and i experienced vibrations when braking.
Maybe that has something to do with the brakes going so fast..
