Don’t do it.

When I opened the box, I was really hyped, as the kit seemed of high quality. Wanted steel lines, as the car is 99% track dedicated.

Started with the left/rear, and I could not get the new line to thread on the OEM fitting. Tried a bit, but it kept cross threading to the point I was beginning to be concerned I was ruining the OEM fitting.

Went to the right/rear, and it went on like butter. Back to the left and it wouldn’t go. Put the OEM rubber line back on, and it threaded.

Move to the front …. And neither would thread. So, 3 of the 4 lines are goobered.

So, will be sticking with the OEM rubber and sending this kit back. Lots of trouble for nothing. Had read where some others had issues, and I guess it’s systemic. Perhaps a bad batch

So i never had issues with threading my 2 front lines, seated and tightened like normal, only issue i had was it never fully sealed. Wasn't going to bother trying rear. Was forced to run my event on oems
I've been in contact with goodridge support, their engineers reviewed my pics and was told to contact vendor for warranty claim which isn't a good sign. Wouldn't suggest going that route, they know something is up.

I ordered mine through wild hammer and they sent me a second set to test again to see if they have the same issue before going the warranty route. Gonna retest my fronts this week. If they have thread issue or leak both sets going back for RMA

I don’t think I feel like trying again anytime soon, so will look to see if I can get a return with the vendor. I was only doing this as a bonus while doing vented pistons. What should have been an extra few minutes ended up taking a bunch of time, only for me to not get the lines on.

IMO … If your flare fittings were not sealing, I suspect it’s because the flare itself is not being pressed down to seal because the nut is not threading. Did it leak right away or only after you used the brakes?

Weird. I bought them for my Mercedes AMG and they fit like a glove.

Yea i actually pushed back on the trying again but i'm on stands anyway so not as much a big deal, plus i'm curious at this point.
Thread tightens down to the line like normal and tq tight as possible, leak was only found after bleeding. Drips from front left under pressure and right about half as much.

So i actually attempted to order mine few months back and they were out of stock, and recently in stock. I'm suspecting issue is with the new inventory.

Weird thing for me was how well the one threaded. So smooth I could practically torque it down with my fingers. I never got to the point of bleeding or putting under pressure though, so can’t say for sure it wouldn’t have leaked.

So I bought the Spieglers for my '22 SS 1LE in late 2022. I had trouble with the RR flare nut to the new line. Felt like it wanted to cross thread. I decided to cut that nut off, bought a new nut and created a new flare. Line went on with no problems. This is not the first time that someone has had issues with installing SS lines, there's other posts here about it.

I gotta wonder if it is a quality issue on the GM flare nut and there's enough variation in manufacturing that the aftermarket threads sometimes have trouble. I don't know.

I tested my replacement set i was sent while i had a wheel off. Installed no issue, cleaned and tightened as expected. Bleed with no issues. Closed the bleed valves and went in and stood on the brakes for a min for some constant pressure. Nice and firm, got happy for a sec. Then peaked back at the lines and saw attached.
This set is leaking about half as much as the previous ones but still doing it.
Reinstalled oem, via same process, and zero issues. Think i'm just gonna stay oem for now.

I considered this as well, but would be hard to test the theory.I never had issues threading and was similarly able to almost hand tight them but the flare is really whats in question for me.

[USMUCL]

I also wondered if it could be the GM nuts . . . or perhaps a combination, i.e. "tolerance stack."

Interesting that mine wouldn't even cleanly thread. That said, since the seal is made by the line flares being pressed against "crush" points in the new lines, I still theorize that imperfect threading has your flairs not mating flush.

Regardless, I'm not willing to try again. This was always just a bonus while I had the front calipers off for vented pistons. Plus, the GM crush washers are very specific and the track fluid expensive. I don't feel like chasing my tail.

I'm already having nightmares about the new pistons leaking, LOL.

Closing this out …. The vendor was RCA Garage, and they handled a warranty claim for me direct with Goodridge. RCA was great.

Goodridge required me only to destroy them and offer a picture as proof …. then they refunded the total cost.

Not sure if that’s indicative of a known problem, or just good customer service. But, alls well that ends well.

Have done several sets of lines and I have found the easiest way is to have the hard line loose when connecting the new line then lock it in place for the final tightening. I also used a brake line flared wrench and got them as tight as possible and they stopped leaking. There is a slightly different flare on the Goodrich lines but they do seal.
