What's wrong, in plain English
Certain Compressible Liquid Adaptive Suspension Systems sold for use on Ram 4500 and 5500 trucks were built so the flexible rear brake caliper line may rub against a suspension part. That contact can wear through the brake line over time. A worn line can leak brake fluid, which can lead to a partial or complete loss of the rear brakes on the vehicle.

Official notice

- SUSPENSION:REAR
- Summary
- LiquidSpring LLC (LiquidSpring) is recalling certain Compressible Liquid Adaptive Suspension Systems (C.L.A.S.S.), part numbers DS135RS3A, DS135RS3AF, DS135RS3-DM, sold for use with 2019-2020 RAM 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. As such, these parts fail to comply with Federal Motor Vehicle Safety Standard (FMVSS) number 105, "Hydraulic and Electric Brake Systems."
- Safety 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.
- Remedy
- LiquidSpring has notified the purchasers, and the affected vehicle manufacturers will file recalls to have their dealers inspect the rear brake caliper flexible lines for wear and install a kit to modify the rear brake caliper flexible line mounting, and if necessary, a kit to replace worn brake lines, free of charge. The recall May 13, 2020. Owners may contact LiquidSpring customer service at 1-765-474-7816, extension 1.
