There is a 9/16 headed bolt at the bottom of the caliper it's on the left side of the first pic. remove that, then there is a slide that you can knock out with a screwdriver. Don't lose the spring, it is a flat shim with the ends turned down so it clips to the thing you slid out. Spread the caliper with the screwdriver so the pads will slide off of the rotor and there you have it. Rich
