Brakes going soft after raising car?

I made them with steel line and bent them with a brake tube bender to mirror factory (as much as I could). The picture of the fittings, all of the flares look like the middle and one on the left. I ended up buying a flare tool to make better flares, that picture shows store bought (left), flares with new tool (middle) and flares with cheap rentals (right)

The only things not new in the brake system is the prop valve and lines from MC to prop valve. I got the prop valve locally from someone. Traded my stock distribution block for his prop valve...

I was going to ask if you used a double flare on those lines. The one on the right looks like a single flare and for brake systems that is bad. That flare won’t hold up under brake line pressures and it will fail. Then you’ll have a big poop sandwich on your hands.
