Thanks
First rule of thumb -- don't force anything. If something won't thread in with finger pressure, or very light help from a wrench, pretty good chance something is wrong and you won't like the outcome. Possible exception of lock or distorted nuts, but even then it should be obvious when something is too hard. Sounds like you're trying to thread the tube nut on the end of the brake lines directly into the Wilwood MC's? Without using the adapter that Papa pictured and is shown in the build manual? Won't work. The Wilwood threads are 1/8 in. NPT. As I recall there's a sticker on the MC that says that. Standard 3/16 in. brake line tube nuts used in these kits are 3/8-24. The adapter is mandatory and should easily thread together. Recommend a touch of thread sealant on the NPT threads into the MC.
