A friend had leaks all over the place because he bought stainless brake lines. Those are especially hard. I suggested copper flare washers and it solved his problems. I ended up going with plain steel pre-bent brake lines and I had a few connections I had to go back to and used the loosen and re-tighten method to get them to stop leaking. I loosened and re-tightened over and over about a dozen times for each connection before re-testing for leaks.

On 3/4 ton trucks I believe the front of the master cylinder goes to the rear brakes, it is on the 1/2 ton trucks the front of the master cylinder is for the front brakes.

I think it's true if you were cross threaded you would have a big leak. So you're almost there...
