Video Transcript for Review of Demco Brake Actuator - Surge Brake Actuator with Lockout - DM8204702

Hello everybody, this is Jeff at etrailer.com. Today we can take a look at the Demco Hydraulic Disc Brake Actuator with the electric lockout and it's for a 2 and 5/16 diameter ball. Has a 20,000 pound gross toying weight capacity and you can see it's in a nice prime finish. Now this hydraulic actuator will activate your trailer's brakes when the 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 a surge brake system like this, this actuator's then triggered as the trailer moves forward once your tow vehicle starts to slow down and when this happens, this actuator will contract, applies force to the master cylinder back here.

And this in turn supplies the necessary hydraulic pressure to engage your trailer's brakes. This one uses a nice acetyl copolymer lining which provides a nice smooth operation as the actuator will telescope in and out. This one does use an easy latch coupler mechanism for a nice, simple, secure hookup and disconnect. Basically, it'll let you hook up when this latch is in the closed position like it is now, you just drop the coupler over the hitch ball and the latch will snap into place. You don't have to get out, open it, close it.

I wanted to try to demonstrate that. I happen to pull, here's a 2 and 5/16 size hitch ball. So if I can lift this up and you can see if I put it on there, with it on there, and then you just put the weight, push it down. If you noticed, it snaps right into place. That lever snapped into place to keep it there and you can see that you're connected.

No problem. So you don't have to open and close the latch all the time and you just leave it in this position. Now when you go to disconnect you just pull up on the latch it's a trigger latch right up here, release it, whoops. And then you'll be able to see once you put that up in the up position, it releases it. You can take it off the ball and now you're detached.

Simple as that. So it makes it very easy to connect and disconnect. And you swing this back over here. This is a heavy duty steel construction. Has a sturdy reinforced outer casing, as we mentioned, has a nice prime finish to it. Now the master cylinder in the back here it is a heavy duty aluminum master cylinder. It's very durable, rust proof, and efficient. It is built for high pressure applications and allows 50% greater displacement than a standard master cylinder. Under this shield back here, you should be able to see there is an electric reverse lockout solenoid. This will let you back up without actuating. your trailers brake. Basically that's solenoid will activate automatically when you shift into reverse. It does have wires on it, so it does have to be wired into your trailer connector, which will then connect your tow vehicle so that it can detect when you're in reverse. It does come with the breakaway cable and the latch hook. That's all included and it is required by law cause this will prevent a trailer runaway situation. And the way it does that is you take your hook, has a latch on it, and you, when you hook up your trailer to your tow vehicle then you take this hook and hook it to the tow vehicle. And what that does is in case this comes detached from the tow vehicle, it will pull on this cable which would activate that lever, which again would allow the pressure in here, supplies the pressure to engage the trailer brakes in a runaway situation. So again, this breakaway cable comes, is included, and it is required by law. Now this is a weld on installation. It is designed to mount to a straight 3 inch wide trailer tongue. It is made in the USA. Specs again, this is, for trailers with hydraulic disc brakes. Gross towing weight capacity is 20,000 pounds. Tongue weight maximum is 2,000 pounds. And this does also go by a model number of DA20. But that should do it for the review on this Demco Hydraulic Disc Brake Actuator with the electric lockout for a 2 and 5/16 diameter ball. Has a 20,000 pound gross towing weight capacity.
