Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
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.
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.”
