LiquidSpring suspension kits on RAM trucks can wear brake lines

NHTSA campaign 20E031000 · Reported 2020-05-13 · LiquidSpring LLC

high How serious is it? About this label

Serious: worn brake lines can cost you part or all of your rear braking and raise the risk of a crash, so act quickly even though no stop-driving warning was issued.

What's wrong, in plain English

LiquidSpring made certain adjustable rear suspension systems that were sold for 2019-2020 RAM 4500 and 5500 trucks. On these systems the flexible rear brake hose is routed so it touches a suspension part. The rubbing wears the hose down, and brake fluid can leak out. That can leave the rear brakes partly or completely useless. The parts also fail to meet the federal safety standard for brake systems.

What you should do

1. Check your VIN at nhtsa.gov/recalls, since the truck maker files its own recall for this part.
2. Contact LiquidSpring at 1-765-474-7816, extension 1, or your dealer to arrange service.
3. The dealer inspects the rear brake hoses and installs the mounting kit, replacing worn lines free of charge.

Official notice

Component: 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.
