If the brake lines are exposed to salt during wintertime, corrosion could ensue. Should the brake lines perforate from corrosion, brake fluid leaks could start causing ineffective braking, which could lead to a crash. On affected vehicles, corrosion could occur either in the area of a four-way joint connector, or wherever the factory hadn't installed resin-cover protection.
Dealers will clean, inspect, and test brake lines for rust perforation. If they're found to be good, dealers will apply anti-corrosion compounds to the areas of concern. If a brake line is found to be perforated, all the brake lines will be replaced on affected vehicles. Complete brake line replacement is very labor-intensive and time-consuming process, so if this proves to be an issue, plan on leaving the vehicle for a day, possibly two depending on the dealer's backlog of cars in line waiting to have other service done in addition to this recall.
The best way to determine if a vehicles is involved in this action is to call local dealers with the vehicle in question's VIN (Vehicle Identification Number) and ask them to run a database search.
