I did a couple searches, and found some related issues, but it wasn't clear if the answers were going to the same part I'm hitting...

I've got a busted hardline at the back of my brake system, and we've got the coupler to splice in new brake line, but I'm not getting any love trying to find the new adapter to go into the center rubber line. (The lower connector in the picture)

I'm thinking I'm looking for a 6mm hardline with a metric adapter ending in a bubble flare? Sound right? By all rights it sounds like Pep Boys should have it (light blue adapter?) but not so

Anyone ever order this online?

 

I have had little success finding adapters/fittings for our cars at local auto parts stores. It seems like as soon as you mention metric fittings and bubble flare brake lines, you are SOL. Most of my trouble is from trying to find fittings to plumb in non stock modifications though. Your case does sound like something local auto parts stores should have or could order. If not you may have to go to your local GM dealer to get it.

You could try making you own brake line. It does not have to be metric sized line. Just get one as close in size as possible to the broken piece. Cut the flare off and discard the fitting if they do not fit your flexible hose. Use the nut from the old brake line. Slide the nut over the new brake line and flare the new brake line with a bubble flare tool. This is what I had to do on my car.

The bubble flare tools are often hard to find. You may have to go to a tool supply store (the guys that mechanics, dealers, garages go to to buy specialized tools) to get one. Another option is to go to the local GM dealer and ask one of their mechanics to flare the line for you. If the guy is cool he may not even charge you for it. I have done this a few times since the bubble flare tools are too expensive to justify buying one.

 

I just thought of another option. How about the salvage yards. They may have this brake line.

 

well, we have 1/4" (6.35mm) line - the old fitting is TOAST. It took a map gas torch heating it orange to get it off. I've been to Murray's, they have some metric stuff, nothing that fits. Autozone was useless, went to Napa and they only carried standard sizes in line and fittings and suggested I visit the chevy dealer. Went to the Chevy dealer and they get all their parts from the Napa I visited -including their brake fittings (WTF?)

I really need some help, we've got it down to this being the only part keeping my car off the road - I've had it over a month and would like to drive it

 

Guys-

Before you start making your own lines or using salvage parts, try going to a hydraulic supply company.

Alot of hydraulic components come from Europe and they usually carry lots of metric stuff.

Much better than an auto parts store......

 

I have the same problem after installing the earls lines in the rear.I have tried 10 different auto parts stores and even midas and meineke were no help. I went to the dealer and they want 50 dollars for a roll enough to go from the front to the back.They also said the line size was 6 mm x 25 bubble flair. It might be the only choice besides getting a used one from the junkyard and double flareing it.Keep us posted how you made out.

 

got the problem solved!

Local auto parts store guy knew exactly how to solve my problem! You install the GM metric to 3/16" adapter (blue) and a 3/16" to 1/4" adapter. This is the solution he nets out to a bunch of people, and we got it on the car and it worked great!

Then mating the 1/4" line to the 6mm line worked out great using the double flare tool and a 1/4" union.

I was _not_ going to find one in a boneyard and I was floored when the guy at Autozone actually pulled out a box of compression fittings!!!

 

We have a store called NOTT CO (formerly called Dadco). They are the people that supply NHRA and NASCAR race teams all their lines and fittings for everything. I have never walked out empty handed or without what I need to finish a job. Br1dgeman knows what he is talkin about. They also are a Parker Push-Loc Outlet. Mavbe you have one of these around you.
