Great write-up! I just wanted to point out two things. One, when you disconnect the brake line from the old caliper, you say to take the cap off the brake fluid reservoir. This will result in brake fluid pouring out of the line. It's better to keep the cap on, and you will lose less brake fluid and make less of a mess. Two is, when you used a bottle or more of brake fluid to bleed the calipers with your buddy's help, you flushed the system. There's no reason to pay someone $100 to flush it again.
That said, great info and pictures! It's interesting to see the difference in parts.
