I've never done it personally but I've read the procedure. You'll need an air compressor. Remove the brake line if it's on there and stick the tip of the compressor in the hole. Use the air pressure to pop the pistons out. It's best to do one at a time, so use something to block one piston while you're removing the other.
when installing the piston into the caliper make sure all is clean and lubed with brake fluid. Hold caliper in vise bore facing up at same time you are starting piston into bore apply light air pressure (blow gun from air compressor) into the brake line fitting while holding the piston up against the seal/wiper boot. Doing this makes the rubber seal around the piston so the correct surface is in contact with piston. Slowlly slide piston into bore so once it's started past the rubber it will slide in. Doing this keeps from having to use a pick or similar to work the rubber around the piston to get it started into the calipers bore without damaging seal.
Only enough air pressure is needed to keep the rubber expanded and sealed to the piston,once started release air.
