What's wrong?
The rear brake banjo bolt on a 2017 Aev Traumahawk ambulance secures the rear brake hose fitting to the brake caliper. That fitting carries pressurized brake fluid into the caliper when the driver presses the brake pedal, so the caliper can clamp the rear brake pads and slow the vehicle. The bolt also helps seal that fluid path.
On affected ambulances with LiquidSpring kneeling rear suspension, the brake line retrofit used banjo bolts with an incompatible torque specification. During installation, that incorrect torque can stretch the bolt or break it. Continued use can leave the rear brake connection loose or leaking, which can lead to partial or complete loss of rear service brakes and result in a crash.
An owner or operator can notice abnormal brake pedal feedback or reduced braking ability before the failure becomes more serious. If inspection finds leakage or looseness at the rear brake banjo bolt, do not drive the vehicle or retighten the bolt.
