A possible problem: the flare on the caliper end is a bit off-center and uneven (it looks worse than the photo shows). Time to step back.

Well, sitting overnight revealed a similar leak from the left rear caliper.

Just like the right side, the line going in to the caliper is leaking, despite a fair amount of tightening on the fitting.

And just like on the right side, the flare seems off-center. (Sorry for the fuzzy photo)

Meanwhile, I was experimenting with cleaning the original Fuchs wheels. I got most of the ancient wheel weight adhesive off from the inside. And then I got out my new citrus cleaner from Chemical Guys.

About 30 minutes with the cleaner and a scotch-bite pad, and the inside is looking good--good enough at least for this wheel, which will be my spare.

The outside also cleaned up a bit, but still has the nasty bit of curb rash.

Back on the brake lines. According to some reliable sources, stainless steel lines are a bit harder, and might take more effort to get the flares to seat properly. They recommend a process of tightening and loosening a fitting, and repeating 5 or 6 times, before a final tightening.

So, starting at the master cylinder, I applied this technique at every junction.

For good access to the fittings on top, I removed the rear calipers. These were the most leaky junctions.

And then re-installed the calipers and connected the flex lines. I still need to get to the fittings on the pressure regulator. But dinner time.

I think so. If you ask the question in a new thread, you will get more answers.

I got my spare mounted, a Vredestein Sprint Classic, 155SR-15, on a stock Fuchs wheel.

This tire is almost as tall as the ones on my 2017 991.

But the 991 rear is just a bit wider.

Test fit in the frunk: the width of the tire is just less than the spare cavity (see the tiny gap below the silver straight edge).
