What's wrong?
The rear brake banjo bolt on these 2017 Horton Ambulance 453, 623, 457, 603, and Cco vehicles is the fitting bolt that fastens the rear brake hose to the brake caliper. It lets brake fluid pass into the caliper while sealing the hose connection, so hydraulic pressure reaches the rear brakes when the pedal is pressed.
These ambulances were built with LiquidSpring C.L.A.S.S. kneeling rear suspension kits. The retrofit used rear brake banjo bolts with an incompatible torque specification, so the bolts were at risk of being stretched or broken during installation. A stretched or damaged bolt can loosen or leak at the brake line connection. Continued use can lead to partial or complete loss of rear service brakes.
Owners can notice abnormal brake pedal feedback or reduced braking ability before the problem becomes severe. If leakage or looseness is found at the banjo bolt, do not drive the ambulance or retighten the bolt.
Who's affected?

- Bring the recall notice if Horton Ambulance has mailed one. If not, reference recall number 17V122 when you call.
