Have you noticed leaking in your yard truck truck brake system or even a malfunctioning of your brakes altogether? You may need a replacement on your Tractor Protection Valve. This protection valve is part of the pneumatic system that maintains the air in the brake system and allows air to pass to the trailer and back to the truck. When this part malfunctions, the air system may leak or fail to release the trailer brakes.
