Mopar Gods forgiveness

Oh ok I think I get it… you cut above or before the rusted nut/ coupler and spliced in from there? Am I understanding that correctly? Just eliminating the rusted damaged sections? The remaining brake hardlines should be ok?
Yes, thats how I did it. Some dont like splices. but I NEVER had an issue with one and a brake shop I talked with said he had installed hundreds over the years successfully. You can probably get a 12" splice/line kit at a local parts store. These are 2 I just see on Amazon- you would just cut off one end and use a connector w/ferrule. https://www.amazon.com/MuRealy-Brake-Line-Repair-Kit/dp/B0CCS1YQ3R/?tag=fabo03-20
