  • Weld-On
  • 8000 lbs GTW
  • No Lockout
  • Straight Tongue Coupler
  • Demco

Surge-type actuator features a corrosion-resistant composite master cylinder and a primed finish. Adjustable channel lets you mount different coupler attachments (sold separately) in 1 of 3 positions. Weld-on application.


Features:

  • Hydraulic actuator activates trailer's brakes when tow vehicle slows or stops
  • Adjustable channel has 3 different mounting positions for coupler (sold separately)
  • Composite master cylinder is durable and efficient
    • Glass-reinforced nylon construction resists rust and corrosion
    • Large reservoir provides increased capacity for brake fluid
    • Automotive-style diaphragm cap creates completely enclosed system to help prevent contamination of fluid
  • Acetal copolymer lining provides smooth operation as actuator telescopes in and out
  • Breakaway included
  • Heavy-duty steel construction
  • Primed finish
  • Weld-on installation
  • Made in the USA


Specs:

  • Application: trailers with hydraulic drum brakes
  • Gross towing weight: 8,000 lbs
  • Maximum tongue weight: 800 lbs
  • Channel width: approximately 3"
  • Channel height: 8"
  • 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 3 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.

Video Transcript for Demco Brake Actuator - Surge Brake Actuator - DM8759922 Review

Today we're going to take a look at the Demco primed hydraulic break acuator. It has an 8-inch adjustable channel center and an 8,000 pound weight capacity. Now this hydraulic acuator will activate your trailer brakes when your tow vehicle slows or stops. The adjustable channel right here has three different mounting positions for the coupler. Now the composite master cylinder right in the front here, if I turn this over, you can see underneath, this composite master cylinder is very durable and efficient. It is a glass reinforced nylon construction which will help resist rust and corrosion.

It has a very large reservoir to provide increased capacity for brake fluid and at the top here, you notice here it has the automotive style diaphragm cap and that'll help create a completely enclosed system to prevent any contamination of your brake fluid. The acetol co-polymer lining on the inside of this will provide a nice smooth operation as the acuator telescopes in and out. The breakaway you can see right here, the cable and the breakaway itself is all included. This is a heavy duty steel construction. You can see it has a nice prime finish to it. It is a weld-on installation and it is made in the USA.

A few specs on this, the application again is for trailers with hydraulic drum brakes. Again, the gross towing rate capacity is 8,000 pounds. The maximum tongue weight capacity is 800 pounds. Now the channel width, let me try to turn this around so we can give you a measurement. The channel width, which is right here that it fits onto is going to be right at 3 inches.

The channel height, which is the adjustable portion right here is going to be right at 8 inches and again it's for mounting onto a straight 3-inch wide trailer ton. Now this does have a standard model number of DA91 and one last thing on this acuator I do want to mention is because this actuator does not include a reserve lockout, it is recommended that you equip your trailer with free backing breaks so that you can drive in reverse without the actuator triggering your trailer brakes. That should do it for the review of the Demco primed hydraulic brake actuator with the 8-inch adjustable channel center and an 8,000 pound weight capacity.

  • Replacement for Dico Model 5 Brake Actuator for 1980 V/M Boat Trailer With 4 Inch Channel Tongue
    Unfortunately, we don't offer a surge coupler to designed to slip over a 4 inch trailer tongue. I tried doing a Google search for a Dico model 5 to locate a recommended replacement, and got zero results and didn't get any results for 4 inch wide surge coupler either. I believe your best choice would be a weld on application like # DM8759922 which would weld to the top of the trailer tongue. You'll want to use a professional welder to do this for you. You'll also need a coupler like #...
