SKU# S4005001030

The ABS Valve (SKU: S4005001030) sold by Ranco.com Parts is a critical component of your anti-lock braking system (ABS) on your commercial trailer. The ABS valve works by dividing the open and closed lines from the master cylinder so it can stop the wheels of your trailer and prevent them from skidding. The rotation speed that the wheels generate is captured by the ABS computer via the wheel speed sensor. When an operator steps on the brakes, the air system sends pressure to the ABS module and then to the wheels. The ABS valve comprises the effectiveness of the ABS module and it is an integral piece of equipment that assures driving capability and safety. It is extremely important to ensure your dump trailer has a well working ABS system and having an operating ABS valve like this part is the key piece to having full confidence in your hauler. Make sure this specific brake valve fits your trailer before purchasing, and if you’re needing other replacement parts to your brake system, be sure to shop our other parts on our Ranco.com Parts Website before you get.
