I just did the very same job new chrome calipers and chrome master. I rebuilt the master with the Suzuki rebuild kit which consisted of a spring, cup, rod and dust seal. I really do not like reusing seals or brake components once they have been removed. I can tell you it took me a long time to get fluid down to the new calipers. I am old school and do the old pump and dump. I finally removed the bleeder valves and poured some dot 4 directly into the calipers. Worked perfectly. I did the pump and dump again and got fluid right away with air. After a few cycles of pump and dump I had a decent brake lever. Let it sit awhile and refilled the master, back to pump and dump and now the brakes are perfect. It did take some time.
I do not think you have a leak if you're not seeing any fluid coming out anywhere. You're just not getting any fluid into the calipers. Pull the lines at the calipers and see if you have fluid to that point. If so, your master is doing its job. Then try to put some fluid through the bleeder valves very slowly (it won't take much). It will take some time but stick with it before you go tearing apart the calipers. I will tell you if you have a leak it will present and if it does not, you're just wasting time and money changing everything out because you will still have a hell of a time bleeding the brakes from all new empty pieces. Personally, like I said when it comes to brakes I would have replaced and did replace the seals and entire guts on the master.
