Rear Brake Line tubing size on Lower Control Arms

I just measured an OD of 5mm on my AE rear control arm.
The batteries on my calipers are dead so this in an eyeball
measurement but its close enough to 3/16 that it probably is.
5mm= .197 3/16th = .186

Fittings i don't know.
I googled "nissan flare brake fitting" and didn't come up with a solid answer.

3/16" --- 4.75mm

Suhhhhhhhhhhhhweeeeeeeeeeeeet.

thanks fellas.

I have those stock lines, I can check the thread pattern when I'm at the shop tomorrow.

no need. i'll take the stainless lines with me and size them up tomorrow morning. then i'll report back.

thanks!

well I think i got all the line i need.

found aluminized copper tubing too.

Also think I found the Z32 to Z31 bmc conversion line fitting. I think it has to be made into a bubble flare at the BMC though, which shouldn't be difficult if the BMC is out of the way.

Bought 3 of them, so if someone wants one…

I got some purple colour coded metric inverted flare brake line fittings, but they don't seem to be the proper ones. I'll have to exchange them in a couple of hours.

They are 11mm hex and they look about 2 mm too short in thread length. They had longer ones with 10mm hex head- which I recall being the size on the flare nuts. I'll be getting those ones.

Damn, these lower control arm lines have to be the weirdest shape.

bent them clean and round with the spring-bending tool and a baseball bat to wrap my bends around (works awesome due to the varying size of the bat).

Dropped in some ATE Super Blue to make bleeding a bit easier- visually… put my new hard-lines in with the new Goodridge stainless lines and all seems well.

My brakes felt firm until I turned the car on- and it got mushy again, so I gotta bleed the fronts and rears again. probably while the car is on to use vacuum assist to aid with the pressurizing of the lines?

I dunno- never had that problem with the last honda I did front hard-lines on.

Normally you'd have to pump them up a few times when you turn on the car.

yeah i know but they still feel a bit more groggy than usual. i'll bleed them in an hour and see what's up.

i have to flush the entire system with the ATE Super Blue anyways, so I'll flush the front lines too.
