What's wrong, in plain English

On certain Ram 4500 and 5500 trucks equipped with Liquid Spring rear suspension systems, the flexible rear brake line may have been routed in a way that lets it contact a suspension part. That contact can wear through the line over time. A worn brake line can leak fluid, which can lead to a partial or complete loss of the rear brakes on the vehicle.

1. Check your VIN at nhtsa.gov/recalls.
2. Contact Braun Northwest customer service at 1-360-748-0195 to schedule service.
