  • 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 Review of Demco Brake Actuator - Surge Brake Actuator - DM8759922

Hello again etrailer fans, I'm Steven. Today we're looking at this Demco hydraulic brake actuator. Now this is an eight inch adjustable channel and this whole component is rated 8,000 pounds gross towing weight. So again, 8,000 pounds, 800 tongue weight. It has an eight inch channel up or down, and three inch side to side. Now you can put your adjustable coupler sold separately in this head.

This channel does have three positions, so two bolts for each position. So you got 1, 2, 3 positions. Now the hydraulic actuator simply activates your trailer brakes when towing vehicle slows or stops. Thus, you know this guy gets kind of pushed together. That's gonna activate automatically by push and brake fluid out to the trailer brakes or camper brakes.

It's got a very nice composite master cylinder here and a nice automotive style diaphragm cap that completely enclosed systems. They're gonna help prevent contamination of fluid and the glass reinforced nylon construction of the tank itself or reservoir rather. That's also gonna resist rust, corrosion, that kind of stuff. Now this does use what's called an acetal copolymer lining. So on this sliding in and out of here is gonna be very, very smooth operation as it telescopes in and out.

It does have the breakaway cable built in already. So simply hook this hook up to your safety chain attachment point on the tow vehicle. God forbid something does happen, it's gonna automatically pull this cable, turn this latch over here and apply the brakes automatically for a safe stopping. Now again, it's a heavy duty steel construction. Very nice made product.

It's got a weld-on installation, so you weld this onto the camper trailer. It is made in the USA. Very nice prime finish as you can see here, you could paint it any other color if you want to. It is considered what's called a model DA91. For those of you that are replacing one, maybe you know the model number, this is a DA91. Does have a nice one year warranty. And again, 8,000 pounds towing capacity, 800 pounds on the tongue weight. This is the Demco hydraulic brake actuator. I'm Steven with etrailer.com. I hope this information's helpful for you. Safe towing out there.
