What's wrong?
The hydraulic brake line on a 2022 Blue Bird Vision School Bus carries pressurized brake fluid through the brake system. Near the Ford 7.3L engine, a small loop-style retaining clamp is supposed to hold that line in place. That clamp keeps the brake line from moving against nearby parts while the bus is driven.
On affected buses, line personnel did not install the retaining clamp near the engine. Without that clamp, the brake line can rub against surrounding hardware. Repeated rubbing wears the line and allows brake fluid to leak. Once enough fluid is lost, hydraulic pressure drops and the service brakes lose function.
Before failure, the driver can see a low brake pressure warning in the vehicle cluster. A visible brake fluid leak is also a warning sign. If either appears, the bus needs service before it returns to route duty.
Who's affected?
The affected equipment centers on the .250 loop clamp used with the hydraulic brake hose and related brake fasteners.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific bus is included in this recall.
What's the safety risk?
Loss of braking ability increases the risk of a crash. A low brake pressure warning or visible brake fluid leakage can appear before the braking problem, so treat either sign as a reason to park the bus and call the dealer. Repair is free at any franchised Blue Bird dealer.
What should I do?
- Check your VIN to confirm your 2022 Blue Bird Vision School Bus is included in this recall.
- Contact a franchised Blue Bird dealer to schedule the free hydraulic-brake-line inspection and missing-hardware installation.
- Ask the dealer to inspect the retaining clamp near the engine, because missing hardware lets the brake line rub and leak brake fluid.
- Bring the recall notice if Blue Bird mailed one. If not, reference recall number 21V778 when you call.
- Drive cautiously until the repair is complete. Avoid hard braking and leave extra following distance.
What happens at the repair
At the dealer, a Blue Bird technician inspects the hydraulic brake lines and checks for the retaining hardware that keeps the line secured near the engine. If hardware is missing, the technician installs it. If the brake line has been damaged, the technician replaces the line as needed. The recall repair is free, including parts and labor. Blue Bird lists standard labor times of 12 minutes to secure the hydraulic brake line and 102 minutes if brake line replacement is needed.
