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. Bolt-on or 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
  • Acetal copolymer lining provides smooth operation as actuator telescopes in and out
  • Breakaway included
  • Heavy-duty steel construction
  • Primed finish
  • Bolt-on or weld-on installation
    • Requires 1/2" x 4-1/2" Grade-5 bolts (not included) for bolt-on mounting
  • 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 Demco Brake Actuator - Surge Brake Actuator - DM8202522 Review

Speaker 1: Today we're taking a look at the Demco Hydraulic Brake Actuator. Now the model number on this is DA20. The hydraulic actuator activates your trailer's brakes when your tow vehicle slows or stops. So you'll notice here at the front it does have the adjustable channel design. This has five different mounting positions for a coupler. Couplers are sold separately, so if you need one and don't already have one, you can find some options at Etrailer-dot-com.Now internally, the unit features a composite master cylinder.

It's very durable and efficient. It's made from a glass-reinforced nylon construction, so it's designed to resist rust and corrosion. Has a really nice large reservoir which provides increased capacity for brake fluid. And it has the automotive style diaphragm cap that creates a completely enclosed system to help prevent contamination of the brake fluid.You'll notice back here is the connection nipple for the brake line. Overall, really nice design.

It's made from a steel construction and it already has the prime finish on it, so that way it can be painted to match to your trailer.Now internally, it features the acetol co-polymer lining, which provides smooth operation as the actuator telescopes in and out. The cable right here is your breakaway cable, so that's included. And it has the clip on here which would connect to the vehicle. So in the event where the vehicle separates from the trailer, it'd pull this cable, pull that lever, move it over to the brakes on position, and then it would activate the trailer's brakes, bringing your trailer to an eventual stop.When it comes to the installation, it can be bolted on. You'll notice it has the bolt on brackets here at the bottom.

Mounting hardware not included. It could also be welded onto the trailer tongue. Now if you want to do the bolt on installation, it does require half inch by four-and-a-half inch Grade 5 bolts, for bolt on mounting. The product is made in the U.S.A., it's designed for trailers with hydraulic drum brakes. The gross towing weight capacity for this unit is 20,000 pounds.

Maximum tongue weight capacity is around 2,000 pounds. The channel width right here, this is designed to accept three-inch channel bracket accessories, so it's about three inches internal width. Channel height from top to bottom overall is 12 inches tall.It's designed to mount on a straight, three-inch wide trailer tongue. And again, the model number on this unit is DA20. Now 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.That's going to do it for today's look at the Demco Hydraulic Brake Actuator.
