Bolts were hand torqued to ~14 lbs(my torque wrench doesn't read accurately that low), the best I could estimate. When it leaked, I tightened a little more each time until I thought I had reached the point where I would strip it. Lines are installed now, I don't need a video, it's just quite annoying that I did this on a Sunday and wasn't able to get it finished until Tuesday because it was leaking(was sick Monday).

Didn't have problems with any of the other lines or hardware.

The thing about it is that even tightened all the way, the lines leaked without applying pressure.

Once the bolt and washers were replaced, no leaks at all while bleeding the system.

Brakes are definitely stiffer now, and I am happy with the pedal response.

Definitely worth the buy.

 

I decided to remove my comment, I'll try being nice...

 

This is just a guess but I think those scores or grooves are there to press a super sealing 3 circle bump crushed washer, or, ridged for the washer's pleasure maybe. A lot of drain plugs have something similar for rubber gaskets. Bad washer or too much torque.
It really didn't seem probable that all StopTechs bolts were getting accidentally precisely machined there. Especially when you see how sloppy the fluid bore hole is cut.

 

Makes sense. Thanks for the input. I noticed that too, but didn't think anything of it.

Must have been the washer. I undid the other 3 lines to check, and only 1/4 bolts had the scoring.

Checked all four Nissan OEM banjos also, and no scoring on those either.
