Features:

  • Hydraulic actuator activates trailer's brakes when tow vehicle slows or stops
  • eZ-Latch coupler mechanism for simple, secure hookup and disconnect
    • Lets you hook up when latch is in closed position - just drop coupler over hitch ball and latch will snap into place
  • 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
    • Snap hook on safety cable ensures secure connection to breakaway lever
  • 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
  • Ball size: 2-5/16"
  • Gross towing weight: 12,500 lbs
  • Maximum tongue weight: 1,250 lbs
  • Mounting: straight, 3" wide trailer tongue
  • Model number: DA10
  • 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.


eZ-Latch Coupler

The coupler portion of this trailer brake actuator features a simple-to-use latching mechanism known as the eZ-Latch. With this mechanism, hooking up is as easy as dropping the coupler over your trailer hitch ball. The latch does not need to be tugged or manually activated to allow the ball into the coupler socket, nor does it have to be secured in place. Just make sure that the coupler is properly lined up with the ball when you lower it, and the rest is automatic.

Video Transcript for Review of Demco Brake Actuator - Surge Brake Actuator - DM8101802

Ellen: Hey everyone. I'm Ellen here at etrailer.com and today we're taking a look at the Demco hydraulic brake actuator. This is going to be for your drum brakes to help you stop safely and effectively with your trailer, so you'll have an item to provide that braking force. This kind of takes the place of a brake controller in your vehicle. It's going to be a mechanical and hydraulic system to apply that braking force to the brakes in your trailer. So as you come to a stop, the tongue of the coupler is going to push on the actuator and force that hydraulic fluid out to your brakes and get everything to a safe stop.

We'll have a nice primed coupler here.This does have a 2 and 5/16 inch ball coupler with the latch at the top, so we can get that secured up. This is going to bolt on to our trailer tongue, so it has this plate at the bottom to go around the tongue of your trailer and bolts in place. It does not come with any hardware for that. You can also weld it on if you prefer. It's just going to require those half inch by four and a half inch grade 5 bolts if you do decide to bolt it on.

The master cylinder has a composite composition, so it's going to be a glass reinforced nylon. So that's going to resist any kind of rust and corrosion. It's also going to have a nice large reservoir, so we'll have plenty of brake fluid to stop our trailer. And it also has a automotive style diaphragm here at the top.It's going to help to keep out any air from contaminating that system, keeps that brake fluid fresh so we don't have to worry about it getting contaminated while sitting in that reservoir. Inside our actuator here, we'll have an acetol co-polymer lining.

So that helps to make the operation smooth as that actuator moves in and out. The whole thing is made out of a heavy duty steel construction.As far as the specs with this, again, this does work for trailers with hydraulic drum brakes. Our ball size is 2 and 5/16. The gross towing weight that this will work with will be 12,500 pounds. Maximum tongue weight will be 1,250 pounds.

Of course, you do want to check with the owner's manual in your vehicle, check your hitch, make sure that you're not exceeding any of the recommended towing weights for your system there. And you always want to go off of the lowest number of any component in your system. The mounting is going to be for the straight three inch wide trailer tongues. The model number for this going to be DA10 and it does have a one-year warranty and it is made in the USA.One last note I want to leave you with is that since this does not include a reverse lockout, it is recommended that you equip your trailer with free backing brakes. That way, you can drive in reverse without having the actuator get triggered as you push that actuator back. This cable here is going to be for your safety breakaway system. So if in the event of an accidental disconnect, this cable is going to pull on this lever and apply the brakes. This just attaches to the safety chain loops on your towing vehicle, but that's going to do it for our look at the Demco hydraulic brake actuator. I hope this video has been helpful in deciding if is going to be right actuator for you. If not, we do have a lot of other configurations available here at etrailer.com, so check them out..

See what our Experts say about this Demco Brake Actuator

  • Demco DA10 Brake Actuator for 4" Square Trailer Tongue
    I do have a solution for you, but the Demco Hydraulic Brake Actuator # DM8101802 is made to fit the more common 3" wide trailer tongues, so the mounting bracket won't work with your 4" trailer tongue. Instead, I recommend the Demco # DM8103102. This is the same actuator you were looking at but doesn't include the mounting bracket. You will be able to weld this to your trailer frame no problem.
