Rick, that may be what I have here. Adapter to the factory Wilwood calipers was provided. It's a straight fitting (i.e. no banjo...I'm familiar with how those work).

My thinking is if you use sealant for the pipe threads on a mechanical fuel pump, why wouldn't you do the same with a brake line that is also carrying a thin fluid that is under pressure?

Because sealant will make a joint more forgiving if there are tiny mechanical discrepancies... up to maybe 100 psi or so.

At the thousands of PSI in a brake system, you have it mechanically perfect or it's going to leak. You hope all it does is leak...
