Melissa, no need for a video. It is the bolt that holds the brake line to the master cylinder. The reason to not let the lever go all the way is because you can let air back into the system.
Your troubleshooting skills are good I would have done the same thing to diagnose the caliper/MC question. Get a friend to help you. Just take off the calipers and stick one brake pad in each. Open the reservoir to ensure you don't run out of fluid. Then pump the lever until all of the pistons are fully extended to the pads. Now you should be able to just wiggle the pistons loose. Get two cans of brake clean, a dental pick, and a wire tooth brush. Use the dental pick to gently pick out the seals. Most likely you can reuse them but it is better to get rebuild kits. Now use the pick, and tooth brush to scrape all the dried brake fluid out. Put the pistons on a buffing wheel. Then reassemble with a thin coat of silicon brake grease. If you have access to a wire wheel buff the slide pins to remove any rust. If not Emery cloth sand paper works. Take a pic of your master cylinder and I'll tell you where the relief while is.
