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 actuator is triggered as your trailer moves forward while the tow vehicle slows. The actuator telescopes, applying force to its master cylinder, which in turn supplies the necessary hydraulic pressure to engage the trailer's brakes.

Video Transcript for Review of Dexter Axle Brake Actuator - Surge Brake Actuator with Reverse Lockout - DX56FR

Jeff: Hello, everybody. This is Jeff at etrailer.com. Today, we're going to take a look at this Dexter DX 7.5L bolt-on disc brake actuator with the electric lockout for a two-inch hitch ball. It has a 7,500-pound weight capacity. Now, you'll use this actuator to synchronize your trailer's disc brakes with your tow vehicle brakes. This hydraulic actuator activates the trailer brakes when your tow vehicle slows or stops.

Basically, what happens is when you apply the brakes in your tow vehicle, the deceleration occurs, and the momentum will push this trailer toward the rear of your vehicle. So, with the surge brake system, this actuator is triggered as your trailer moves forward while the tow vehicle slows. The inner portion of this actuator will telescope in. It applies force to the master cylinder, which in turn, supplies the necessary hydraulic pressure to engage your trailer's brakes. If you look on the front of this, has a nice low-profile coupler latch to ensure easy, secure connection.And when I say "low profile," it doesn't have anything sticking up high like on some of your couplers, has a latch way up high that, after time, it could get hit and get bent, things like that.

This one's all nice and low-profile, out-of-the-way coupler latch. Now, this is an over-the-center latch mechanism, which will only engage when the actuator is fully seated on a two-inch hitch ball. And what I wanted to do is demonstrate that. Here's an example of a two-inch hitch ball that this will fit on. First thing you want to do is when you go to install it, you'll slide out this tethered safety pin here, and that'll let you open the latch.

And the way you open it is this little knob right up at the top, this rounded portion. Just slide that, and it'll release, and it's spring-loaded, opens up.Now, you're ready to attach. Here's your two-inch ball, drop it right over it. It attaches on there, put the latch down to lock it into place. And then, for extra security, you'll slide this safety pin back in.

And what that safety pin does, what's nice is if, by chance, this got hit and it actually opened, it wouldn't open all the way, so it stays attached. That pin will keep it from opening all the way. And then, to remove it, again, just slide out your safety pin, move that latch open, and then, you can just disconnect from the hitch ball. Simple as that. Very easy connection and disconnection from the hitch ball.Now, this also does include this breakaway cable if you notice here. This breakaway cable is required by law. Basically, what this cable does, it prevents a trailer runaway situation by applying the brakes on the trailer. And the way it does that, this should always be hooked to your tow vehicle, so if, by chance, this comes disconnected from the hitch ball and goes into a runaway situation, this cable will be pulled, which would activate the brake system back here, and it'll apply the brakes on the trailer, keep it from a runaway situation.Now, this one does include the electric reverse lockout solenoid right back here. I raised that up, you can see in there some wires. There's an electric reverse lockout solenoid that will let you back up without actuating your trailer brakes. Basically, that lockout is automatically activated when you shift your tow vehicle into reverse. The solenoid wires that are on there will wire into your trailer connector, and that connector connects to your tow vehicle, so it'll detect when you go into reverse. The solenoid will ensure that that hydraulic actuator does not activate your trailer's brakes and allow you to back up your vehicle.Now, to use that feature, it does recommend that you have a five-way, six-way, or seven-way trailer connector on your vehicle. The master cylinder, you flip this down, you'll be able to see the end of the master cylinder right here. It is constructed of aluminum rather than plastic or steel. It gives you increased strength and corrosion resistance. And right above where the master cylinder is, it has this nice flush brake fluid filler cap. And the reason it's nice and flush, the same way you don't have. A lot of the caps are very tall, and they can get hit and broke and things like this. This one's nice and flush, so prevents it from any damage.And the same way, you just twist it to open it, check your brake fluid or put in more brake fluid. Now, this actuator does have a zinc-plated finish, which offers excellent corrosion resistant, and it is a bolt-on installation. You can see the holes back here. It is designed to fit a three-inch by five-inch straight trailer tongue. This part is made in the USA. Again, the application is for hydraulic disc brakes. The ball size it fits on is a two-inch diameter, and the weight capacity is 7,500 pounds. But that should do it for the review on the Dexter DX 7.5L bolt-on disc brake actuator with the electric lockout for a two-inch hitch ball and has a 7,500-pound weight capacity.

Review from a similar DX7.5L in Brake Actuator


I slipped this into my boat mate trailer for 2001 moomba. Took about an hour to hook up and bleed the system with a buddy. Works great! If you can use simple tools and are mechanically savvy this is a no brainer.

Review from a similar DX7.5L in Brake Actuator


I received my order two days ago, Quick shipping but it was the wrong part. I called and spoke with Noah who sent me an email asking me to take a picture of the part and add my phone number. I did right a way and still have not heard back. I emailed Noah today asking about the status no reply, now Im on a 9min hold to try and talk with someone about my replacement past. The wrong part looks like a good part if it fit my trailer.


Comments
Mark, Im sorry Noah didnt reply to you in a timely manner. We will get this taken care of and send out the correct part.

The product is exactly what I ordered and it was shipped quickly. Only problem is it is missing the upper cap to cover the brake fluid reservoir. I did call Customer Service and they said they would send one ASAP. The photo online shows it is included with the product. I’m waiting on receiving it.

This product doesn’t fit over 3” tongue. Its the exact same size as a 3” tongue.Unusable. Had to remove the internal portion and modify my trailer tongue to fit. Arrived as the worst packaged item I’ve ever received. It was barely still in the box. Whom ever packaged this didn’t have a clue what they were doing.
