I guess I'm glad that I'm the only one having issues with brake line failures. I bought the truck new in Salt Lake City, and moved to the Gulf Coast. Yeah, I drive it on salted roads in the mountains, and take it to the beach. But I had two other cars that I drove for 10 years each in the same conditions, and never had a brake line fail.
Now, have you folks looked at the routing of these brake lines? If you do, you'll see what I mean about the job being easier if you take the ABS module out of the equation. I don't know if I can get those 4 lines that run from the engine compartment to the ABS module in there. The brake lines were probably originally installed before the frame was put on.
