Video Transcript for Review of Dexter Axle Brake Actuator - Replacement Inner Slide - DX39FR

Jeff: Hello everybody, this is Jeff at etrailer.com. Today, we're going to take a look at this replacement inner slide for the Dexter DX 7.5L disc brake actuator for 2-inch hitch balls. It has a 7,500 pound weight capacity. Now this is the replacement inner slide that'll fit into your existing outer housing on your Dexter DX 7.5L or the legacy UFP disc brake actuator. Basically this inner slide is the portion that will telescope inside the outer housing of your surge brake actuator upon breaking, and it applies the force to the master cylinder to supply hydraulic pressure to apply the brakes on your trailer. If you notice on this one, it uses a nice low-profile coupler latch to ensure nice, easy, secure connection.

This is an over center latch mechanism, which will only engage when the actuator's fully seated on your 2-inch hitch ball. And I want to demonstrate that, I happen to pull a 2-inch hitch ball that this would fit onto.And just to show you how to install this, you pull out this tethered safety pin right here that allow you to open the latch. If you look on top of the latch, it has this round portion that goes back and forth. If you just push that over it'll release it, and that'll open up your latch, just like that. And with your latch open, you can see that when you're over the 2-inch ball, it'll fall right into place, put your latch back down, and now you're hooked onto the ball.

And then for extra safety, slide this safety pin all the way through, and that'll keep the latch locked onto the ball. If by chance this does get hit or something and it unleashes it or unlatches it, that latch won't open all the way it'll still stay attached to the ball, and then you just push it back down.And then to totally remove it, just slide your safety pin back out, slide open your latch, and that'll open all the way, and you can remove it from the ball just like that. So it's a very simple way to connect and disconnect from your hitch ball. Also, if you notice it has this breakaway cable, which is included. Now this breakaway cable is required by law, this will attach to your tow vehicle.

And what this does is when it's attached, it will prevent a trailer runaway situation. So if this trailer happened to become detached from your tow vehicle, it would pull on this breakaway cable, which would then activate the master cylinder to apply the brakes on the trailer to prevent a runaway situation. Now, the master cylinder itself, let me flip this over and you'll be able to see it. Right here, this master cylinder is a constructed of aluminum rather than plastic or steel. It gives you a nice increased strength and corrosion resistance.And if you notice on the back of the master cylinder right here, you'll see it has the Selectric reverse lockout solenoid.

This will let you back up without actuating your trailer brakes. The solenoid, you can see the wires here is wired to your reverse light circuit, and it activates automatically when you shift into reverse. Again, the application on this is single axle trailers with disc brakes. The ball size we mentioned it fits on is a two inch diameter hitch ball. Weight capacity is 7,500 pounds. But that should do it for the review on this replacement inner slide for the Dexter DX 7.5L disc brake actuator, for 2-inch hitch balls. It has a 7,500 pound weight capacity..

I received the inner slide damaged. The inner slide was in a cardboard box with shipping paper. The hydraulic fitting was at a 45 degree angle to the fitting and 1/2 of the threads were damaged/pulled off where the fitting was threaded. In addition, I proactively requested help to verify my inner slide to ensure I was going to order the correct one. The one I received is not a direct replacement as the rear pin is no where near the correct location. The only way to potentially make it work is to drill a new hole through the trailer to accept the new slide. I want to return this unit and get the correct replacement that will install without modifying my trailer.
