Since I live in Northeast, have to face the rust issue. I have been watching 2 metal brake lines between ABS module and master cylinder inside the engine bay degrade to the point that spot with white powderlike substance has eaten into the surface of the metal tubing. Probably roadsalt, that has a super easy access to the engine bay - the truck is '99 so it has exposed engine bay from the bottom. Should I replace? If so, is disconnecting lines between ABS and master cylinder a DIY job - in regards to relieving pressure etc? I don't want to damage ABS module.

Please advice, thanks in avdance.

I would have it done ASAP I have a 1994 f150 and I was lucky the line burst in my drivway as I was backing out truck. It cost me about $150

Is changing brake lines between ABS and master cylinder a DIY job? I used to routinely change lines on cars without ABS, but this one is different. Please help.

Sorry I can't be of more help. Mine did not have ABS and I just ran it to the local gas station and he replaced 2 lines. Good luck
