NHTSA campaign 20V313000
Hazard
Frazer is recalling certain 2019-2020 emergency vehicles built on RAM 4500 and 5500 chassis, equipped with certain Compressible Liquid Adaptive Suspension Systems (C.L.A.S.S.), part numbers DS135RS3A, DS135RS3AF, DS135RS3-DM. 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.
Consequence
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
Frazer will notify owners, and dealers will 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. This recall is expected to begin June 1, 2020. Owners may contact Frazer customer service at 1-888-372-9371.
