Brake rotor goop?

I'm in the process of going through all my brake components and came upon this unusual substance cementing the "crossover" brake line to the front caliper. At first I thought the previous owner had gooped on some epoxy when he was splashing on that nasty red caliper paint but then I saw that all original AP calipers have this setup. Is it there purely to support the tubing or is there some complex engineering secret that I am unaware of?

It's just for support. They can be plastic, rubber, foam, or silicone adhesive in this case.

Ditto. This silicone survived when I used paint stripper to remove color from a set of calipers I put on the back of my Exige.

You can imagine the small motion that the tube would experience over time. This little up and down motion eventually makes the material brittle or works the fasteners loose. This material holds the tube in place to reduce the motion.
