Pretty much, the only thing Brain knows is. 1. Shalltear was around E-Rantel 2. Momon defeated a vampire near E-rantel.

We the readers know it was shalltear, but to everyone else it was a random strong vampire, even Brain does not know whether it was or wasn't shalltear, he might suspect but that doesn't mean he knows.

Even if he did however, he could not link Shalltear and Momon to Nazarick much the same way he's well acquainted with Sebas tian and he doesn't suspect that he's from nazarick either.
