  • 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 5 positions. Weld-on application.


Features:

  • Hydraulic actuator activates trailer's brakes when tow vehicle slows or stops
  • Adjustable channel has 5 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
  • Breakaway lever activates your trailer's brakes if the trailer disconnects from the tow vehicle
    • Snap hook on safety cable ensures secure connection to lever
  • Acetal copolymer lining provides smooth operation as actuator telescopes in and out
  • Heavy-duty steel construction
  • Primed finish
  • Weld-on installation
  • Made in the USA


Specs:

  • Application: trailers with hydraulic drum brakes
  • Gross towing weight: 20,000 lbs
  • Maximum tongue weight: 2,000 lbs
  • Channel width: approximately 3"
  • Channel height: 12"
  • Mounting: straight, 3" wide trailer tongue
  • Model number: DA20
  • 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.

Video Transcript for Review of Demco Brake Actuator - Surge Brake Actuator - DM8203322

Hello everybody, this is Jeff at etrailer.com Today we're gonna take a look at this Demco 12" Adjustable Channel Center Hydraulic Drum Brake Actuator. It has a 20,000 lb weight capacity. Now this Hydraulic Actuator will activate your trailer brakes when your tow vehicle slows or stops. Basically, what happens, is when you apply the brakes in your tow vehicle, deceleration occurs and the momentum will push your trailer toward the rear of your vehicle. So with the surge-brake system the actuator is then triggered as your trailer moves forward, once your tow vehicle starts to slow down. So when this happens, this actuator will contract and applies force to the master cylinder in the back here.

And this in turn supplies the necessary hydraulic pressure to engage your trailer's brakes. Now, they do use an Acetal copolymer lining between the inner and outer case. It provides a nice smooth operation as this actuator telescopes in and out. You'll notice on the front here, it is an adjustable channel. It has five different mounting positions for your coupler.

Now, the coupler is not included. We do sell that separately on our website. The channel height on this, if we put a ruler on it, the very bottom to the top, you can see is right at 12". And the channel width, which will always be measured inside the inside, is gonna be right here at 3". If you notice, this has a nice prime finish to it to help prevent rust and corrosion.

It is a heavy-duty steel construction, and we've mention the master cylinder in the back here. It is a composite master cylinder, which is durable and efficient. It is a glass-reinforced nylon construction which will resist rust and corrosion, and it offers a large reservoir it provides increased capacity for your break fluid. And right up at the top here you can see it has an automotive-style diaphragm cap, which creates a completely enclosed system to help prevent contamination of your break fluid. Right here you can see it does have the breakaway cable.

That's all included with the hook on it. Now this breakaway cable is required by law, and it'll prevent a trailer runaway situation. Basically what you'll do is, when you hook up, you'll take this hook and hook this to your tow vehicle. So with this stretched out, in the case of it if it becomes detached, it'll pull on this cable, which will activate this lever, which again, will apply the brakes in a runaway situation. Now this is a weld-on installation mounting. It's designed to mount onto a straight 3" wide trailer tongue. This part is made in the USA. Application, again, this is for trailers with hydraulic drum brakes. Gross towing weigh capacity on this is 20,000 lbs. Maximum tongue weight of 2,000 lbs. This part also goes by the part number of, our model number of DA20. One last note I do wanna mention on this actuator is because this actuator does not include a reverse lockout, it is recommended that you equip your trailer with either a reverse lockout solenoid, that'll install right back here, or to have free-backing brakes on your trailer, so that you can drive in reverse without the actuator triggering your trailer's brakes. But that should do it for the review on this Demco 12" Adjustable Channel Center Hydraulic Drum Break Actuator, with a 20,000 lb capacity..
