    NHTSA recently issued a warning to those that live in the salt states about rusting brake lines. The upshot of the multi-year study behind the advisory was that GM and other truck makers installed brake lines that did indeed suffer corrosion in the states with rough winters where salt is used on roadways. The corrosion caused failures and accidents. These were documented in the report. GM later changed its brake line design to add a more robust protective layer. That is likely the most cost effective way to prevent trouble, but is it the best way?

Some readers wrote in to say that replacing brake lines is inevitable and changing them as part of long term truck ownership should be expected. We looked for products that might offer a better than OEM resistance to corrosion and found that stainless brake lines are offered. Indeed, Dorman, one manufacturer, markets the stainless brake lines as a solution to this very problem. Looking at the Dorman site we noticed right away that the kits are primarily for 2000 to 2006 model year GM truck and SUV models. Exactly those that might be due for a replacement.
