The short answer
NHTSA received Halcore Group, Inc.’s report on May 23, 2020. Copied from NHTSA on Oct 19, 2026.
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.
Halcore Group, Inc.
(Halcore) is recalling certain 2019-2020 American Emergency Vehicle TraumaHawk 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, 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.
