Well, it's basically a tension (like a tension on a string) that wants to cause the brane to contract.

Well, for that to be the case, it would need to be independent of scale. That is, if I stretched the brane (via cosmological expansion), the tension would remain the same. This may be the case, but I'm not so sure.
