+1...Common problem. You do not have to remove the caliper. After you get the pad off, then carefully pull out the two pucks that are attached to the shim. They fit tight into the pistons and have a tendency to corrode. Clean and use sparingly copper anti seize on the pucks and between the shim and new pad. An alternative is to delete the shim/pucks entirely as they will not affect the operation of the brakes. I did several years ago (done all the time by everybody on the track) and I'm still waiting for the first squeal or chatter. just insert the new pad with just a little anti seize on the outside sliders and the piston face. Don't forget to pump the brakes and check the reservoir before you back the car out of the garage or you'll get a real scare, been there done that......
