At some point i usually replace flexible brake lines as part of a brake job, usually around the 100k mark or 10 years. But i'm not in the rust belt. Some things i replace before problems start.
Wouldn't be a BITOG brake thread without "make sure them flex lines ain't plugged in one d'rection".
Because its good advice. Brake lines do degrade, and while not extremely common, but on occasion, with age, they do fail internally and collapse when the master cylinder is released.
I prefer with brakes, to replace some items that are aged during a brake job, rather than wait for a brake line to fail on the road. I had this happen and it's not fun. It's also being considerate of the other drivers around you.
