I ordered a set of Goodridge stainless steel brake lines as I'm going to redo the brake system. I ordered part number 22054 which is for 2008-2012 coupes and convertibles with the sport brakes. I just figured it would be identical for the 2013's.

Well, I just read over on the370z.com forum that they changed the rear line setup slightly in late 2012 and I'm assuming this also pertains to the G37. Which is why it doesn't say it's compatible for the 2013 model year. Great.

I can't find an online application guide for Goodridge products, U.S. car lineup. I'd like to stick with the Goodridge lines as they generally route them exactly like the stock lines and use the brass distribution blocks. They're also TUV/DOT approved. I'd go with the Z1 lines but I do not believe they're DOT approved and not willing to take the chance.

Am I just SOL on using Goodridge stainless brake lines? I don't see an application for a 2014 Q60 either.

What change did they make? Is it something to do w/ the placement of the distribution fittings? Interested to hear what exactly they did, and why??

I inured the difference out. There are no brass fittings in the rear, just clips. Basically you'd need to go with non-sport (no metal lines out of caliper) rear lines and Sport front lines. I'm SOL. Just going to skip lines altogether as I'm not willing to risk things with the Z1 lines.

Presto

I moved the ss brake lines from my 09 sport coupe to my 13 sport coupe. I had got the lines from racing brake along with my 2 piece front and rear rotors . I did not notice any difference and the lines fit. I have tracked the car few times. Now I'm worried lol.

They changed the rear lines in late 2012 in the U.S. They may or may not have changed them in the U.A.E. If your lines looked identical and had the brass distribution blocks, chances are, they didn't change them in 2013. If you go to Z1's site, look up their premium lines. They have a build date for before and after 06/2012. The front brake lines are still the same.

If they worked on your car, you're probably just fine.

Presto

Mine is a USA spec car with an early 2013 build date. Will take a look at the oem rear lines I removed and see what they look like.

Ok lines made it to my mailbox despite USPS's best efforts not to deliver the items I order.

Rear lines:


Fronts are identical for all years so I know they'll work.


I will say this; they're heavy suckers. The package had a good deal of heft to it for a few hydraulic lines. Solidly made though and DOT approved. I won't have time to look at my rear brake lines until late in the weekend.

Ok took a look at the rear brakes on Sunday and did some comparison photos. I need to check my vehicle's build date but it is a 2013 and I would assume made in the fall or winter of 2012 at the earliest.

Here are pre-06/2012 rear braided lines from Goodrich.


Here's one end the stock brake line that'll be replaced showing the fitting which is identical to the Goodrich line on the same end.


Here's the brass block end of things, stock and the Goodrich line. Looks pretty much the same, right?


Now here's a closeup. Notice on the stock line, there's a U-shaped "clip" for lack of a better term which surrounds the hose end. But it doesn't actually clip in to anything. It looks like it's there to keep the assembly from rotating when tightened. This is a 2013 MY vehicle.

It looks like I'd be fine using the pre 06/2012 brake line here. Can anyone else see or think of a reason?

Looks like it ll fit, the best thing to do, is just to try it out...

That can be a dangerous thing with brakes. But point taken. I checked with Z1 this morning and sent them photos. They said shouldn't be a problem. I'd still like to know what exactly is different.

Edit: My build date is 08/2012 so theoretically, it should be the new setup. I've contacted Z1, even though I didn't buy the lines through them, to let them know and sent them photos. I think I heard Spencer say they have the same fitting on both ends (no brass block) on the later models. Would be worthwhile to check before ordering.

Another update, it's not the rears that changed, it's the front. I was going to pull a wheel tonight after work but I'm wiped. I'll get around to it sooner than later but Z1 told me one of the ends on the updated lines doesn't have the block.

Long overdue...here's the difference in brake lines pre and post 06/2012.

Pre-06/2012 Goodrich PN 24-5127
Post-06/2012 Goodrich PN 24-5117

I've only seen one shop that lists both part numbers and that's Welcome To Motorsport & The Z Store! Nissan-Datsun 240Z-260Z-280Z-280ZX-300ZX(Z31/Z32)-350Z-370Z Parts! I've searched high and low for a Goodrich catalog with part numbers and I've never found one.

I made the mistake of ordering the pre-06/2012 lines despite the fact I have a 2013 model year. I thought it was an error on the vendor's part. It's not.

So what's different? The front lines have one fitting that's different.

Here's the pre-06/2012 front lines. If you look at the bottom right of the photo, you'll see the lines terminate in a brass block. On the later model years, it's a straight fitting and it eliminates the brass block.


Here's a photo of that portion of the brake line on my car:

One last update. I was about to pull the trigger on the 06/2012+ Goodridge lines. I'd mentioned to Spencer at Z1 that I really wanted a DOT approved line. He inquired and the lines are indeed DOT approved from Z1 so I ended up purchasing from them.

Goodridge has one advantage over the Z1 lines, specifically the front lines. If you look at the photo of the front lines above, the Goodridge lines are permanently affixed to the center brass block just like OEM. The Z1 lines screw in and are a potential leak source if not threaded and screwed in correctly.

I found this thread after the fact. I fortunately have flare wrenches for the install.
