Brake Line Fitting Size
 

What is the brake line fitting size for '83 SC?

I will be removing all 4 calipers and sending them out for full restoration. Upon removing, I would like to cap/plug the brake lines so the fluid doesn't drain out. I've not determined if I will plug/cap at the hard line or rubber soft line, but know the cap will need to be a male/female depending on where the plug goes.

Is the fitting size for 911 brake lines M10 X 1? Or something different?

Would a plug like these work?

I saw a trick recently - the bleeder screws fit the female end of the flexible line and can be used as plugs. Clever.

Admittedly, if you are removing all four calipers I'd likely drain the system and fill with fresh anyways unless you recently did so.

I just flushed the old fluid out. Not against doing it again, but would like to keep the system free of air while the calipers are out being restored.

I didn't think about using bleeder screws --- seems like the same idea as a plug. And, a more economical solution too

Back to my question --- is M10 X 1 the correct size?

Thanks!

Yes, M10 X 1 is the correct size

Appreciate the reply/confirmation here DJ.
