Line wrench size for rear brake lines

[Rymanrph]

I got ready to swap out my rear brake line for a longer line last night and when trying to remove the flex line, the fitting was giving me some trouble. It seemed to be somewhere around 3/8", but my 3/8" line wrench was way too big. Maybe 11mm?

 

Anyway, I sprayed it down with some PB Blaster to let it sit for a while. I just don't want to round off the fitting trying to remove it. Can someone tell me what size line wrench I need to get it off?

Are you asking about the end of the rubber hose itself, or the flare nut on the steel line that goes into the upper end of the hose?

The flare nut that goes into the rubber hose right where its held in place with the C clip. I have a new longer Dakota hose to swap in.

It's metric for sure, 10mm IIRC. get yourself a set of metric flare nut wrenches. Your nuts will thank you. :D

Actually, it's a 3/8" SAE.

Ah well, must be a Renix thing. All my brake line flare nuts are metric. Sorry for the confusion. :(

No, I have the flare nuts and the flare nut wrenches spread out on the garage floor right now because I'm re-doing all the hard lines on a 2001 Cherokee. Not a metric brake line fitting in sight.
