The defect
Custom Truck And Body Works is recalling certain 2020 Dodge 4500 and 5500 vehicles. In the affected suspension systems, the rear brake caliper flexible line may have been routed so that it contacts a suspension component, possibly causing excessive wear and a loss of rear brakes.
The risk
A worn rear brake caliper flexible line may cause brake fluid leakage, which may result in a partial or complete loss of the rear brakes, increasing the risk of a crash.
