The defect
Braun Ambulances (Braun) is recalling certain 2019-2020 Demers MXP170E Type I and MXP150E Type I 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.
The risk
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.
