NHTSA campaign 20V291000
Hazard
Halcore Group, Inc. (Halcore) is recalling certain 2018-2020 Horton Emergency Vehicles (HEV) Type I & Type III ambulances built on a Ram 4500 or 5500 chassis and equipped with 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. The affected system component is the rear brake caliper flexible line which may be causing brake caliper to wear due to contact suspension components.
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
Halcore 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 began June 5, 2020. Owners may contact Halcore customer service at 1-800-447-0343.
