Brake Line Fitting Size

[spinaldex]

I'm looking to stick an electric line locker where the hard line meets the soft line at the rear locker (short "why": axle swap, rear disks, no longer have an ebrake and need a temporary hold to give the foot a break when winching).

Now, the break lines are 3/16 right? But, I've been reading different posts and some say the fittings are 3/16 and other say the fittings are 3/8. Anyone know for sure which one?

Most of these line lockers come with 2 female 1/2" holes, so I want to get a few adapters and see how this works.

Thanks!

No one knows what the size and type of stock fittings are on the main line to the back?

They're 3/16, except at the proportioning valve, where they switch to metric.

I found like 15 different answers to this. Some people say that its 3/16 tubing with 3/8-24 fittings, others say its 3/16 fittings. Are you sure its 3/16? That looks super small to me looking at the fitting.

3/16 brake line with 3/8 fittings for the most part. its really best to take the fittings/line with you to make sure you get what you need
