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..

This replacement inner member slide fits into the existing outer member housing of your Dexter DX7.5L and Legacy UFP surge brake actuator. For use with single-axle trailers with hydraulic disc brakes.by: Robert 05/02/2024
Exactly what I needed. Everything fit as described. Doing business with etrailer is always a pleasure. From help with ordering the correct parts to answering any questions, they alway have come through for me. Will definitely use them again when needed.

Direct replacement for my UFP actuator. Install was a little tricky. I couldn't screw on the brake line because the brake hose couldn't twist enough to screw it on. So I unbolted the entire tongue with the new actuator in it so I rotate the entire tongue to screw the brake line into the new actuator. Worked well. Actually didn't even need a wrench on the brake line. Bled the system with a power bleeder and no leaks noted. Seems great so far. Have not trailered the boat yet.

Perfect fit replacement for my 20 year old trailer's master cylinder and coupler. Snap ring pliers, wire strippers and connectors and a couple of wreches to hook up the brake lines are all you need to make a quick replacement. My old one needed a new shock absorber and back up solenoid. Installing a whole new unit made more sense and I'm really happy with his replacement.

A year with several long road trips 300+ miles and dozens of local trips and the actuator is still working like new.The only change Id like to see is the ability to use a more robust locking pin to secure the trailer. The small diameter pins that will fit through the coupler bend easily.
by: John 08/10/2023
These guys are great, my purchase was straight forward but due to the amount of corrosion on my existing brake actuator I was having an extremely difficult time removing it. I called their help phone number included in the package and left a message on a Saturday afternoon. About an hour later a representative called me back and confirmed what I was doing was correct and gave me some ideas to aide the disassembly. The installation was a success!
by: John S03/11/2022
SHIPPING WAS FAST AND GREAT FOLLOW UP AFTER THE SALE. I HAVEN'T INSTALLED THE PART YET BUT IT IS AN EXACT REPLACEMENT FOR MY BASS CAT BOAT TRAILER. I'M SURE IT WILL WORK AS WELL AS THE 17 YEAR OLD ORIGINAL.

The Dexter brake accuator is still doing what its supposed to. Installation was somewhat simple after removing some rusty parts from the original. New unit installed easily and works great after a good bleeding of the lines.

Shipment was delivered sooner than expected. Will be installing this weekend. I should have went this direction in the first place instead of just replacing parts within..

Customer service was amazing, actually got to speak to someone! That’s hard to find these days.. Very helpful and was able to answer all my questions, and the price was much lower than other places I looked, plus it had free shipping!
by: Anthony11/07/2021
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.

Customer Service will contact you about the damaged item. This is our only inner member we have for a single axle wdisc actuator.
by: William 04/24/2023
Everything worked as you said. Bolted right in place. No problems at all.
by: Craig10/04/2022
Great product, easy to install. Poor shipping, the cardboard container was destroyed when it arrived. You can't put a heavy, solid metal object in a cardboard box with a handful of crumpled paper and think it will survive the delivery.
by: Ronny 09/28/2022
Perfect fit on a 1983 Ranger Trail Trailer, previously modified for disc brakes, and surge brake application.

Replacing an old actuator that wasn’t working properly looks to be 31 years old, should end with reviews that include, “amazing, works great, such a relief, should have done it sooner, and the peace of mind is well worth the money “. So accept those. I’d add, my first one did not function properly. I could not get it to apply pressure to the new disc brake assembly. I was near the end of etrailer’s return policy period, but they took the return and even sent out the new one before I had removed the “old” new one. Once I installed the replacement, pressure applied instantly and has been functioning as it should. My Mastercraft Prostar 190 on the trailer only weighs 2200 lbs, but I do feel relief and no consideration while towing. The product, and equally importantly—etrailer’s customer service makes this purchase a 4.95 star rating.

view full answer... - What Is The Difference Between Dexter # DX99FR And Dexter # DX39FRThe main difference between The Dexter Inner Membrane # DX99FR and The Dexter inner Membrane # DX39FR is that the # DX99FR is for a tandem axle with disc brake setup. The # DX39FR is for a single axle with disc brake setup. Both Dexter membranes have a 2 inch ball size and have a weight capacity up to 7,500 pounds. They both have an electric reverse lockout that lets you back up without actuating the trailer brakes. The solenoid activates automatically when you shift into reverse. I...

So the # DX39FR can be used on a trailer with one braking axle, while the # DX99FR can be used on a trailer that has two braking axles.
view full answer... - Why Does Reverse Lockout Solenoid of Replacement Inner Member for Dexter DX7.5LSome reverse lockout solenoids have one wire as they ground through the coupler to the frame whereas some have a separate ground wire like with the Replacement Inner Member for Dexter DX7.5L part # DX39FR. The blue wire would get ran to the reverse circuit and white wire gets ran to the ground.

view full answer... - Replacement Surge Brake Actuator For a Painted Trailer With UFP A-60 ActuatorTo determine if the Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-20 will work in place of your current brake actuator you will need to verify you have enough 3" wide channel to mount the actuator. This actuator is a little shorter so depending on the length of the tongue and your payload area or boat as it may not allow you to use the other actuator. We do have the Replacement Inner Member # DX39FR you can use to basically give you a new actuator.

This is the replacement inner member for Dexter DX7.5L and Legacy UFP Brake Actuators like your UFP A-60 so it would be exactly the correct replacement.
view full answer... - Replacement Master Cylinder and Inner Member For Dexter A-75 Surge Brake ActuatorWe do have the Replacement Master Cylinder Assembly # DX44FR or Inner Member # DX99FR (tandem axle)/ Inner Member # DX39FR (single axle) for your Dexter A-75 master cylinder. If the master cylinder is the only damaged part that is all you will need to replace.
view full answer... - Solution for Replacement Inner Member for Tie Down 75LPWithout the rear pin hole it does not look like the Replacement Inner Member # DX39FR will fit. The other pin holes also do not appear to line up. I would not recommend attempting to modify the housing to make this fit either. Also, this inner member is designed for a single axle. A dual axle would require the # DX99FR. The only solution would be to replace the entire actuator with one like the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout - Bolt On - Disc - 2" Ball - Zinc - 7.5K...
view full answer... - Does The Replacement Inner Member # DX39FR Use The Aluminum Master Cylinder? The Replacement Inner Member # DX39FR uses the Master Cylinder Assembly # DX44FR with its durable aluminum construction. The brake components including the master cylinder are only compatible with DOT 3 and DOT 4 Brake Fluid. DOT 5 cannot be used as it will damage the internal components.
view full answer... - Comparing Replacement Inner Member for Dexter DX7.5L Actuator Part DX99FR and Part DX39FRThe only difference between the Replacement Inner Member for Dexter DX7.5L Actuator part # DX99FR and part # DX39FR is that the former is for tandem axle trailers with disc brakes and the latter is for single axle trailers with disc brakes or tandem axle trailer with drum brakes. I don't recommend using either actuator outside of these parameters.
view full answer... - Do You Carry Just the Inner Portion Of The Dexter DX7.5L A-60 Brake Actuator For Disc Brakes? We do have the Replacement Inner Member for Dexter DX7.5L Actuators and Disc brakes. You would need to select the Single Axle # DX39FR or Tandem Axle # DX99FR version.
view full answer... - Replacement Inner Member for Tie Down 75LP Brake ActuatorThe Replacement Inner Member for Dexter DX7.5L Actuator # DX39FR is the correct replacement for Dexter DX7.5L and Legacy UFP Brake Actuators which includes your Tie Down 75LP. The two wires are connected to the reverse lock-out solenoid, one of the wires would be grounded to trailer frame and the other connects to your reverse light so when you reverse the solenoid locks out the coupler allowing you to back up the trailer.
