Interesting find today. The inside of the tire was wet with BFS again.
I pulled the right front tire and brake caliper off. Sprayed it all down with BraKleen.
I found that the brake line banjo bolt was not tight(I could move the line on the caliper).
I tightened it and went to the other side and it was slightly loose also(it did move with some effort).
I set the right caliper back in place and will wait a day and see if everything looks dry.
I guess, even though I was very careful not to pull on the brake lines while installing the new front springs, I must have pulled them a bit.(just enough to move them and cause the leaking).
I do recall last year, as I installed the 2 new front calipers, that I didn't like the cheap looking solid copper washers(for the banjo bolt) that came with the calipers. The originals had concentric rings in the surfaces. I recall not feeling any squish, just a tight bolt.
