You need to push the piston back into the calipers alittle. I used a screwdriver (carefully). Then, the caliper & pads come off as one. BTW I found a great trick to push the piston all the way back into the caliper. I used 2 of those "Quick Grip-mini bar clamps" You know those 'one handed' clamps that you use to hold 2 pieces of wood together. You put one on opposite sides of the piston, and start gripping tighter. Took me 30 seconds to collapse them back in. And very easy! Finding a 7mm allen wrench was not
