The defect
Halcore Group, Inc. (Halcore) is recalling certain 2017 Horton ambulances, models 623, 603F, 453, and 457, built on Ford F-350, F-450, or F-550 chassis equipped with Compressible Liquid Adaptive Suspension Systems (C.L.A.S.S.) made by LiquidSpring. Due to an incorrect torque specification, the rear brake caliper banjo bolts may have been overtightened.
The risk
The improperly tightened banjo bolts may result in a partial or complete loss of rear brake power, increasing the risk of a crash.
