NHTSA's recall notice

As NHTSA's recall record states it for campaign 20V284000.

Defect description

REV Ambulance Group Orlando, Inc. (REV) is recalling certain 2018-2020 Type 1 ambulances built on Ram 4500 and 5500 chassis equipped with Compressible Liquid Adaptive Suspension Systems (C.L.A.S.S.), part numbers DS135RS3A, DS135RS3AF and 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.

Safety 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.

Manufacturer remedy

REV will notify owners, and dealers will 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 began July 15, 2020. Owners may contact REV customer service at 1-855-661-9232.

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
