There's really nothing wrong with the brake lines.
I ordered these for a customer's Chevy 1500. Whether it was my researching fault or not these did not end up fitting. I tried contacting the seller for return period that was almost a week ago. I never got an authorization to return the item comma as well as it set a 20% restocking fee if I did. This is usually what happens when somebody is Drop Shipping items period no return to my message and charging a high fee to return it so overall I'm not pleased with the transaction
