Hope this helps and not hinders!
I have changed my rear pads (2015 Spyder F3) three times and the trick is to balance the caliper on a piece of wood or brick and to insert a pair of long nosed pliers into the two holes on the piston and to Push and Turn at the same time. I have noticed that if the pads are really worn then the piston seems to have gone beyond its thread and turning has no effect - you then have to support the caliper and push and turn at the same time. One time out of three I just had to screw it back in so I have learned the hard way!
BTW - I need a rear caliper repair kit - any ideas?
