Help with front brake leak

[*hotrods*]

Ok here's the deal. I'm doing a frame off nut and bolt restoration on a L78 69 Camaro. I went to bleed all the brakes and when I got to the front passenger side I noticed a leak were the hose connects to the caliper. I tried to tighten it and it still leaked. I then replaced the crush washer and it still leaked. Here's the kicker, everything is new including the hose, washer, caliper and crush washers.

So rather than have a leak a decided to replace everything again. I got a new factory style hose and bolt from Ricks 1st Gen. and got a new caliper from a different parts store. Well guess what, it leaks also. I went as far to take a 1/2" breaker bar to tighten then bolt and it still leaks a small bit, almost like a seep now. What is going on here? I have replaced hundreds of brakes before and never had anything like this.
