Actuator features a corrosion-resistant composite master cylinder and zinc plating with a 200-hour salt spray rating. Manual lockout keeps brakes from actuating when in reverse. Adjustable channel lets you mount different couplers (sold separately).

  • Manual reverse lockout lets you reverse without actuating your trailer's brakes
    • Rotate tab on actuator to left before backing up to activate lockout
  • Composite master cylinder is durable and efficient
    • Glass-reinforced nylon construction resists rust and corrosion
    • Large reservoir provides increased capacity for brake fluid

  • Breakaway included
  • Heavy-duty steel construction
  • Zinc plating offers corrosion resistance
    • 200-Hour salt spray rating

Specs:

  • Application: trailers with hydraulic drum brakes
  • Gross towing weight: 8,000 lbs
  • Maximum tongue weight: 800 lbs
  • Channel width: approximately 3-1/2"
  • Mounting: 3" wide channel tongue
  • Model number: DA91
  • 1-Year warranty


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.


Manual Reverse Lockout

This actuator has a manual reverse lockout that you can activate so that you can back up without triggering your trailer's disc brakes. To activate the lockout, just rotate the tab on the side of the actuator to the left. Once the lockout has been activated, you can back up your trailer without triggering the trailer brakes. Always remember to restore the tab to its original position before towing normally.


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 200-hour salt spray rating. In addition, the composite master cylinder is made of corrosion-resistant glass-reinforced nylon to further ensure durability.

  • 2 inch Coupler Recommendation for Demco Hydraulic Brake Actuator w/ Manual Lockout # DM8760011
    For a 2 inch hitch ball coupler to fit the 3 inch channel of the Demco Hydraulic Brake Actuator w/ Manual Lockout # DM8760011 the Bulldog Collar Lok coupler part # BD028584 would fit and work well.

  • Demco Hydraulic Brake Actuator for Drum Brakes with Lockout
    The Lockout Solenoid Kit # DM5837 you referenced is not designed to fit the DA86 model of Demco actuators, which is the part # DM8608601 you referenced. There is an alternative option for a similar hydraulic drum brake actuator with a lockout that I recommend checking out, the Demco Hydraulic Brake Actuator w/ Manual Lockout - Drum - Zinc - 8" Adjustable Channel - 8K # DM8760011. This is just the channel portion of the coupler and I recommend adding the Demco Trailer Coupler - Adjustable...

  • Replacement Surge Brake Actuator Assembly for Boat Trailer 3" Straight Bolt Pattern
    The Demco Hydraulic Brake Actuator # DM8669112 will fit the 3" frame on your boat trailer. I have attached a picture that will show the different bolt patterns as this on will sit above the frame and not quite on the frame. The 3 hole straight that you have will have bolt holes that are 0.85" below the top of the frame while the 3 hole standard holes on the # DM8669112 are 1.5" below the top of the frame rail. I recommend the Demco Hydraulic Brake Actuator w/ Manual Lockout # DM8760011....

  • Is Lockout Solenoid Included With Titan Brake Actuator Coupler # T4750700
    The Titan Zinc-Plated Brake Actuator, part # T4750700 you referenced does not have a solenoid included. There are three types of systems you can choose from. Either a system like part # T4750700 that has no solenoid, a coupler with manual lockout, or brake couplers with an electric solenoid lockout. If you are wanting a brake coupler with an electric lockout I recommend the Titan Zinc-Plated Brake Actuator w/ Drop Electric Lockout, part # T4750720. This has the same features as the coupler...

  • Actuator Needed to Use Demco Manual Reverse Lockout Kit For Hydraulic Brake Actuators
    No; the Demco Hydraulic Trailer Brake Actuator # DM72VR is designed for use with free-backing brake systems and does not have a lockout feature- so you wouldn't be able to use the Manual Reverse Lockout Kit # DM5939 with that actuator. To use the Manual Reverse Lockout Kit you would need an actuator like the Demco Hydraulic Brake Actuator w/Manual Lockout # DM8760011 . This kit requires 1/2" x 4-1/2" Grade 5 bolts (not included) for mounting as well as a coupler similar to # CT-5003-Z...

  • Recommended Replacement Surge Brake Actuator For Atwood 85778 For Drum Brakes or Disc Brake Upgrade
    You are correct that parts are no longer available for your Atwood 85778 brake actuator. I recommend the Demco Hydraulic Brake Actuator w/ Manual Lockout # DM8760011 as a replacement if you wish to keep your drum brakes. A Demco Trailer Coupler # DM12688-95 will attach to the 3" channel on the actuator for a 2" ball connection. It really comes down to if you are happy with the performance of your current drum brakes. I like seeing disc brakes used in heavy duty applications, on boat...
