What's wrong?
In NHTSA campaign 17V660, the air-brake drop hose on 2015-2018 Ic Bus Resb and Re school buses is the flexible air line that feeds the service brake chamber at the steer axle. When the driver presses the brake pedal, air pressure travels through this hose so the brake chamber can apply the front brakes.
On affected buses, the drop hose fittings were not clocked at the correct angle. With the wheels turned fully and the suspension moving, the hose can sit too close to the tire or rim. The tire can rub the hose, wearing through the outside of the line until air leaks during braking.
A pre-trip inspection can show abrasion on the drop hose before the line opens further. The driver can also hear an air leak when the service brakes are applied, or feel the bus pull during brake application as the leak gets larger.
Who's affected?
Covers the Resb and Re bus lines across the 2015-2018 model years, all tied to the same brake system component.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
Brake air hose contact with the tires can damage the hose, make the brakes inoperative, or lengthen stopping distance, increasing crash risk. During inspection, look for hose abrasion. An air leak, brake pull, or worsening pull during braking means stop using the bus and call the dealer. Repair is free at any franchised Ic Bus dealer.
What should I do?
- Check your VIN to confirm your 2015-2018 Ic Bus Resb or Re school bus is included in this recall.
- Contact a franchised Ic Bus dealer to schedule the free repair for the misoriented air-brake drop hose fittings.
- Ask the dealer to reposition the drop hose fittings and replace any damaged drop hose or wheel speed sensor harness so the brake hose no longer rubs the tire.
- Bring the recall notice if Ic Bus mailed one. If not, reference recall number 17V660 when you call.
- Inspect for brake hoses touching the tires before use, and keep the bus out of service if a hose is damaged or braking feels abnormal.
What happens at the repair
At the dealer, the Ic Bus technician repositions the air brake drop hose fittings so the hoses stay clear of the tire when the wheels are turned fully. The technician also replaces any damaged drop hose or wheel speed sensor harness. The recall repair is free, with parts and labor covered. If you already paid for related work before the owner notice, Navistar's reimbursement plan applies. Follow the reimbursement instructions included in the customer notification, and keep repair invoices or payment records with your paperwork.
