I've been reading up a lot on this issue of before 06/2012 vs. after 06/2012. I recently picked up a set of Techna Fit lines that were supposed to fit 2013 MY.

https://conceptzperformance.com/tech...v36_p_3142.php

Upon receiving the lines and performing additional research I learned about the minor change Infiniti made to the brake piping in 06/2012. See details below. Basically they changed the front brake lines from a banjo bolt type connection to a "retaining clip" system like the one in your pic above. The rears remained the same. You can see the difference if you compare a 2013 FSM to a 2012 FSM too, section BR-20.

I got all worried and contacted CZP saying that their product description was wrong, but I'm FAIRLY certain that the difference between pre-6/2012 and post 6/2012 only matters if your front SS line is the type that re-uses the front OEM hard brake line to the caliper. Both the goodridge and the Z1 PREMIUM lines are manufactured in this way, which is why they are shorter and have a brass block.

The Z1 STANDARD SS lines, Technafit lines, Stoptech lines, all have a longer stainless with no brass blocks and a banjo bolt type of connection. These types of lines go DIRECTLY from the caliper (via banjo bolt) to the hard line on the frame of the car.

At this point I am just conjecturing because there are very few people with 2013 MY cars and SS lines. Even those that do (4DRZ if you are reading this...) don't recall the minor details of the install. I am planning on the install this weekend and am hoping for the best.

The change is the inboard fitting, one closest to the inner fender wall, NOT the fitting on the hard line running off the caliper.

I should have updated this thread with photos but I did do a DIY installation thread where there are photos in the DIY section.

Z1 lines for 06/2012 and up (the V-shaped two-piece is the front)


Good ridge lines for 05/2012 and below (just the fronts)

Yup thats what I was expecting to see! Thanks tor the pics and elaboration, I think ive already seen your diy thread but didnt realize it was you.

I guess what I'm trying to get at is that the distinction between pre and post 6/2012 only matters if the aftermarket front lines run from the frame to the inboard fitting that you mentioned. In other words, setups that do not require you to remove the oem hardline piping. This is because the change is at the inboard fitting.

for aftermarket "long" front lines that go straight from caliper to frame (and require removing the oem hard line coming out of the caliper), there should be no distinction between 2012 and 2013.

Does that make sense to you at all or do you think I'm going to have issues during this install?

Edit: actually I think when you say "inboard fitting" you are referring to the connection sitting on the inner fender wall, which was not what I was expecting. Doesnt the fsm show that the change was at the outboard fitting?

Yep, you'll still have issues as the fitting in question is on the other end of the line opposite of the hard line that runs into the caliper. It makes things a PITA. I will say this, I've had no issues or leaks with the Z1 lines and I personally would not run a line that doesn't follow the OEM rout and mounting methods/points. Goodridge does have an updated line.

Ape Factory

It's inboard, not outboard. If you look at the goodridge lines with the brass block at the end, that's the same end as the new lines from Z1 which only has brass block in center. The outboard fitting is identical on both (closest to caliper).

Thanks for all this info!
Im going to do ss lines on my 13 IPL.
Im guessing ill need to determine build date or is knowing its a my13 good enough?

@PNW_IPL: just look at your door sill sticker, it will say the build date of your car. Mine is MY2013 and build date was 09/2012.

@Ape Factory: your DIY thread said "While mostly the same, this is for cars made 06/2012 and on. The difference before that date can be seen in the front lines which has an additional brass block on the outboard side of the line." I am still fairly confident that the standard Z1/Stoptech/Technafit lines, the inboard fitting should be the same. Anyway, I guess I will find out for sure this weekend.

PNW_IPL, I will keep you posted so that you know what your shopping options are...all we know for certain is that if you are purchasing SS lines that follow OEM configuration (hardline to hardline), e.g. Z1 premium lines, Goodridge, you MUST make sure to buy the model that is designed for 06/2012 vehicles or later.

For the non-OEM configuration lines (e.g. Stoptech, Technafit, Z1 standard lines)...well that is where Ape Factory and I are disagreeing. I will find out this weekend...

Thanks man. My build date is 4/12

Update: I put the lines on. I've driven maybe 20 miles with the new lines, no leakage yet. I am getting a clinking sound but I believe that has more to do with something that happened during the install and not due to the lines, maybe I left a bolt loose or something. That being said, I'm uncomfortable with the way the lines are routed. The OEM hard line neatly routes around the back of the wheel spindle, and because it's a hard line, there is no flex and no potential for the line to come in contact with anything. The same cannot be said for any aftermarket line that runs straight from the caliper to the frame.

Overall I would agree with Ape, although the Stoptech/Technafit lines do FIT, I definitely would prefer the OEM setup. It feels so unnecessary and wasteful to remove the OEM hard line. The installation would have been MUCH simpler and the routing much "safer" if the hard line were re-used.

It's an even bigger deal for 2013 MY cars because the design of the OEM brake line includes a metal plate that juts out of the spindle as part of the OEM brake line configuration. It was tough getting the aftermarket lines to clear this plate and it is unnerving to see the brake line so close to this plate.

Darn man. No good.

As a follow-up to the noise I mentioned earlier, it was my battery which had gotten slightly dislodged and was making a metal clinking sound while driving. Thankful it wasnt something brake related.

OEM mounting is the only way to go. The Z1 premium lines aren't that much more and Goodridge does make a line for 06/12 and up build dates. I've had zero issues with the Z1 lines leaking. Did it once and was done.

My car is a 2013.
My build date is 04/12
My front lines have retaining clips at both ends.
I thought i should have a brass block at one end because im before 06/12?

Ape Factory

It should according to everything I've read. You're positive on the build date? That's a pretty early build date to be a 2013.

PNW_IPL

Positive. I lowered my front and checked the lines to see.

Its a 2013 IPL. Canadian model. Of that means anything.
It definitely has clips at the caliper and where it connects to hardline. Only brass is in middle where it attatches to knuckle.
