PL Custom Emergency Vehicles (PL Custom) is recalling certain 2019 Dodge RAM 5500 emergency vehicles equipped with the LiquidSpring Compressible Liquid Adaptive Suspension Systems (C.L.A.S.S.). 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.”
