What's wrong?
The quick release valve in the air brake system on 2017-2018 Evans Flatbed Trailer models helps release brake air pressure at the right time. Inside that valve is a diaphragm, a flexible sealing piece that moves with air pressure and keeps air routed where the brake system needs it.
On affected trailers, that diaphragm is exposed to constant pressure from the supply side of the brake system. It was not designed for that use. Over time, the diaphragm degrades, and air leaks from the quick release valve. When the brake system loses air through that leak, the emergency brakes engage instead of staying released for normal travel.
There is no warning sign before failure. An owner or driver can discover the problem only when air starts leaking from the valve or the emergency brakes engage.
Who's affected?
This recall is tied to trailers built in a specific production window, so matching the model year is only the first screen.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
Partial or full emergency brake application can overheat the wheel end or create drag that slows or stops the trailer, increasing crash risk. If the trailer feels like it is dragging, slowing unexpectedly, or resisting tow, pull over safely and contact the dealer. Repair is free at any franchised Evans dealer.
What should I do?
- Check your VIN to confirm your 2017-2018 Evans Flatbed Trailer is included in this recall.
- Contact Evans customer service at 1-704-436-2590 to schedule the free service-center repair.
- Ask the service center to install the heavy duty diaphragms in the quick release valves, the repair that stops air-brake leaks that can apply the emergency brakes.
- Bring the recall notice if Evans has mailed one. If not, reference recall number 17V632 when you call.
- Keep extra space and stop using the trailer if the brakes drag, the wheel-end overheats, or the emergency brakes apply before the repair.
What happens at the repair
At the service center, an Evans technician installs heavy duty diaphragms in the quick release valves so the air brake system no longer leaks through those valves. The recall repair is available now, and the installation is free of charge. Parts and labor are covered under campaign 17V632. Schedule the trailer with an Evans service center and ask what access they need to the brake valve area before the appointment.
