I've got a 97 dodge ram 1500 that I've did the 2500 brake upgrade on. I ordered the jegs steel brake lines and put them on a few weeks ago as well, I just noticed that on the driver side both of the copper brake line cones or fittings where they go into in steel brake lines are leaking. Is there anyway to fix them or do I just have the replace the whole line?

 

Is the brake line that's leaking pre-bent/pre-made for your specific truck? If so, I'd try tightening the nut at the leak point with a good quality flare nut wrench. I ran into a similar issue, but my pre-bent brake lines were made of stainless steel, which definitely required extra tightening to get many of them to stop leaking, due to the hardness of the metal.

 

I agree with Atomic, I'd tighten them up a little more with a flare wrench.

Did you have any trouble installing these lines? I just replaced a number of brake lines on my truck and I had a few connections that were in odd spaces and were difficult to get them lined up just right. Wondering if something like that could of caused an issue for you.

 

I had a '97 Dakota that all the lines were one system and the fittings were the other. I don't remember which was metric and which was SAE, but I had to put adapter fittings in all of them. Without the adapters, they would tighten, but not seal.
