Description

This is a replacement aluminum construction Trailer Disc Brake Master Cylinder for Demco Brand surge actuator Actuators, which comes with the Demco reverse bypass Solenoid assembly Preinstalled. If your Hydraulic Trailer Disc Brake Actuator is not performing optimally, it may just be the Master Cylinder that is the issue. Replacing the Master Cylinder can often cause a Hydraulic Trailer Brake System to work like new again, since you will have to empty all the lines and re-bleed the brakes, it is a good way to flush out any troubling parts and make sure everything is installed and working at peak performance. This master cylinder has a corrosion resistant sturdy aluminum body, so you don't have to worry about rusting out the inside of the master cylinder reservoir!

This aluminum body master cylinder is similar in size to the Composite Construction Demco Master Cylinder with Reverse Bypass, but it has a few key differences. The aluminum construction master cylinder has a larger 1 1/4" bore, while the standard composite has a 1" bore, effectively allowing the master cylinder to push more fluid to your trailer's brakes. This makes this aluminum assembly the top choice for triple axle trailers that need the extra pressure to properly actuate their disc brakes. However, using this larger bored master cylinder can cause issues with smaller single axle and tandem axle trailers; since the extra fluid can cause your brakes to "shudder" when the brakes are applied. Because of this key difference the aluminum master cylinder is installed as standard equipment on Demco actuator's over 10,000 lb capacity.

This Master Cylinder kit makes replacing parts and repairing the Actuator Unit even easier since it comes with the required electric Reverse lockout bypass solenoid pre-installed. 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.

Features:

- Disc Brake Master Cylinder

- Pre-installed Lockout Solenoid

- Easy 4 bolt installation, hardware included

- fits DA66b, DA86, DA91, DA10, DA16, and DA20.
