Tie Down® Disc Brake Actuator.
The oversized master cylinder delivers all the pressure you need for your disc brake trailer! That's up to 6,600 pounds of SAE-certified capacity. Just bolt it on, hook up your 5-pin connector, and the Actuator delivers the kind of safe, reliable braking you want.
Featuring an electric solenoid that senses when your vehicle shifts into reverse and locks out the brakes for trouble-free hauling, even when you're on soft ground or backing up a hill. Steel construction, aluminum cylinder. Break-away cord sets and stops the trailer in the event of separation.
