Here is our Trailer Disc Brake Master Cylinder with a Pre-installed Electric Reverse Lockout Solenoid for Demco Actuators. If you're having problems with your trailer's Hydraulic Disc Brake Actuator not performing optimally, it may just be an issue with the Master Cylinder. Replacing the Master Cylinder can often cause a Hydraulic Trailer Brake System to work like new again! Since you will need to re-bleed the brakes and clear the lines, it is a good reason to flush out the lines and make sure everything is working at its best.
Since it comes with the required electric Reverse lockout bypass solenoid pre-installed, this Master Cylinder makes installation even easier! The Lockout Solenoid receives power from your Tow Vehicles Reverse Lights to allow you to reverse your trailer without the brakes engaging.
This Master Cylinder is the OEM replacement for the Disc Brake Versions of Demco Actuator Models DA66b, DA86, DA91, DA10, DA16, and DA20.
