Help with damaged left rear caliper brake line while mounting lowering spring

While mounting the Eibach lowering springs I ''of course'' stupidly damaged the hard brake line of the rear left caliper. And yes the line is pinched and definitely have to be replaced.

I checked the online GM parts store and this specific line in not listed, only the entire caliper.

https://www.ebay.com/itm/35346410752...29a6%7Ciid%3A1

I've heard places selling rebuild kit for most calipers and I was wondering if anyone knows any places that would sell this line and avoiding buying the entire caliper.

Any advise would be greatly appreciated..

On a side note for the one thinking mounting lowering springs, my advise is not trusting too much the Youtube videos. The front was fairly easy but the back is a PITA and none of the videos address the re-alignment necessary including camber re-adjustment, re-clocking the rubber bushings, torque specifications and rear camber adjustment bolts requiring replacement each time.
Just be aware that it is a lot more involved than the videos make it look.

That looks like it would be fairly easy to recreate. I make my own brakelines for my road race cars. Buy a decent quality flaring tool and a small hand held bender. Then buy a length of brake line and practice making that shape using the original as a template. Once you get the hang of it, bend up a duplicate piece. Then flare both ends (do NOT forget to slide the fittings on the end before flaring lol). It should fit right on. (Then paint it red of course )

PS any time you lower a car it changes the toe and camber and will need to be realigned. It also changed the corner weights and it should be re corner balanced too

Thanks for your reply! if I can't find a direct replacement I will definitely explore that route.

I was aware of re-clocking and full realignment after lowering but how is re-corner balancing done?

I feel your pain. I took the calipers apart to get powdercoated for my SLC, I discovered one of the crossover lines on the calipers was bent....but didn't notice this until a couple years after I got the kit. I looked everywhere to find a replacement, unfortunately no luck.

FYI SLC uses Gen5 SS Brembos. Considering I never could find a replacement line or part number, hate to say it but you may be in the same boat.

- Get the tools and make it yourself.
- Remove it to bring it to a local place that will bend it up for you.
- Find a used caliper to purchase, take the crossover and resell the caliper as is.

I didn't do any realignment for mine with Eibach springs. Quite frankly, I don't think its really that necessary for the amount of drop you're getting. It may be off slightly from OEM settings, but probably still in spec or close to it. Been driving mine this way for almost a year now, tires are wearing fine.

Sorry to hear about the mishap.

For future reference to anyone that wants a proper procedure for installing lowering spring. Use the SG3 Sport Suspension install document from GM.

It's severely pinched/flatten. Needs to be replace for sure. If it was only cosmetic I would've just touch them with some paint has I painted these.

I think you are right, make one might be the cheapest way to go about this.

A new caliper on Ebay is $311

Toe and camber will change perhaps not in a significant and noticeable way.

Have you re-clocked the rubber bushings or it was fine?
