Demco Brake Actuator - DM8758721

    • 500-Hour salt spray rating - great for marine applications

  • Breakaway included
  • Heavy-duty steel construction
  • Bolt-on installation
    • Requires 1/2" x 4-1/2" Grade-5 bolts (not included) for mounting
  • Made in the USA


Specs:

  • Application: trailers with hydraulic disc brakes
  • Gross towing weight: 8,000 lbs
  • Maximum tongue weight: 800 lbs
  • Channel width: approximately 3"
  • Channel height: 12"
  • Mounting: straight, 3" wide trailer tongue
  • Model number: DA91
  • 1-Year warranty


Note: Because this actuator does not include a reverse lockout, it is recommended that you equip your trailer with free-backing brakes so that you can drive in reverse without the actuator triggering your trailer's brakes.


When you apply the brakes in your tow vehicle, deceleration occurs and momentum pushes your trailer toward the rear of your vehicle. With surge brake systems, the hydraulic actuator is triggered as your trailer moves forward, once your tow vehicle starts to slow down. When this happens, the actuator contracts, applying force to its master cylinder. This in turn supplies the necessary hydraulic pressure to engage your trailer's brakes.


Adjustable Channel Design

The adjustable channel on this trailer brake actuator allows for ultimate versatility. Mount almost any type of coupler (sold separately) - from a standard ball coupler to a lunette ring or clevis attachment - to fit your specific application. In addition, the 5 mounting positions on the channel let you adjust the height of the coupler. Just place the coupler so that it matches the height of the ball mount or other hitch attachment on your tow vehicle and you will be able to tow your trailer levelly.


Sturdy, Corrosion-Resistant Construction

Made of sturdy steel, this hydraulic trailer brake actuator features a durable zinc coating that is designed to limit rust and corrosion. This zinc coat has a 500-hour salt spray rating, making the actuator perfect for marine use. In addition, the composite master cylinder is made of corrosion-resistant glass-reinforced nylon to further ensure durability for marine applications.
