Hi, oficially yes, but you can get away with a screwdriver used like a tommy bar. DON'T turn them in the wrong directioon or they'll release the handbrake mechanism from the piston which is a pain!. I found the safest way is to put a G cramp losely over the piston so you'll know when you're going in the right direction. Other than that is't relaticely easy!!
Good luck, rehards, Gordon
