I found all 4 calipers were leaking at the banjo bolts as well as a few hard brake lines. The lines were no big deal, I even expected it a little. I purposely try not to tighten flared lines too tight for fear of crushing the double flare. I find the leaking lines and loosen and tighten them (a little tighter each time) until the leak stops. The C5 front calipers just needed to be tightened to the correct 30 lb ft of torque.
The rear Explorer calipers were more of a pain. They take 22 lb ft. (which I did), so I loosened them up and torqued again 3 times. Still leaked. I snugged the banjo bolt and then turned the hose block with a wrench back and forth to try and seat the copper washers. The leak was less, but still there. I loosened and torqued to 24 and then loosened and torqued to 26. That did it.
With the leaks addressed, I pumped the brake pedal several times and then stood on it for a solid minute. Checked again and no leaks. Now I can bleed all 4 corners.
This isn't done for me (the leaks) until a test drive with everything heated up and another check of every connection, but as you can see, that won't be for a while.
Looks nice though
