What's wrong?
The 2014-2015 West-Mark Sugar Tank trailer uses air brake actuators, also called brake chambers, to turn air pressure into braking force at the wheel ends. Inside each chamber, a rubber diaphragm moves under air pressure and helps apply or release the service and parking brakes. When the diaphragm seats correctly, the brakes release cleanly after the driver lifts off the brake or releases the parking brake.
In the recalled Haldex Life Seal Type 30/30 Long Stroke chambers, the rubber diaphragm is not completely attached in the parking brake assembly. That bad seating can keep brake force partly applied after release, which creates brake drag. Dragging brakes build heat at the wheel ends and can wear or damage brake parts.
During a pre-trip or post-trip walk-around, the warning sign is discoloration at the wheel ends. Treat that discoloration as a brake heat clue, not a cosmetic mark.
Who's affected?
Covers one Sugar Tank configuration across 2 model years, tied to the same air brake system.

| Units affected | 7 |
A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
Brake drag can overheat the wheel end and result in a wheel end fire. Watch for discoloration at the wheel ends during pre-trip and post-trip walk arounds, and treat that sign as a reason to stop using the tank until it is checked. Repair is free at any franchised West-Mark dealer.
What should I do?
- Check your VIN to confirm your 2014-2015 West-Mark Sugar Tank trailer is included in this recall.
- Contact a franchised West-Mark dealer to schedule the free Haldex air-brake actuator replacement that fixes the brake-drag risk.
- Bring the recall notice if West-Mark sent one, and reference recall number 16V399 when you call.
- Ask West-Mark customer service at 1-800-692-5844 if you need help locating the repair path.
- Use caution when moving the trailer before repair; brake drag can overheat the wheel end.
What happens at the repair
At the dealer, a West-Mark technician removes the Haldex Life Seal Type 30/30 long stroke air brake actuators and installs Haldex Gold Seal Type 30/30 long stroke actuators. The recall repair is free. West-Mark has already notified affected customers, and parts and labor for the actuator replacement are covered through the recall. The service work addresses the brake chamber diaphragm problem that caused brake drag on the affected Sugar Tank trailers.
