    I would suggest opening the master cylinder (where you add brake fluid) and getting a woodworking type clamp from a hardware store to slowly push the piston back into the caliper bore. Be very careful not to scratch the piston or damage the rubber seal around the piston. When you have pushed the piston back in and installed your brake pads dont forget to re-tighten the master cylinder lid.
