Features to know about
Smooth Braking on Every Stop: Hydraulic Surge Design for Disc Brakes
The Titan Zinc-Plated Brake Actuator uses a hydraulic surge design that automatically synchronizes your trailer’s disc brakes with your tow vehicle’s braking. As the trailer moves forward during deceleration, the actuator telescopes to apply pressure through its master cylinder—giving steady braking power right when it’s needed. Designed for disc brake systems, it delivers the 1,400–1,500 PSI range typical of disc operation with no residual back pressure.
Backing Up Without Brake Drag: Built-In Electric Lockout
Getting into tight spots or reversing up an incline is easy thanks to the built-in electric reverse lockout solenoid. When your tow vehicle shifts into reverse, the lockout automatically activates through a 5-pole flat, 6-way round, or 7-pole wiring harness. This keeps the trailer brakes from engaging as you back up, so there’s no fighting resistance or needing to manually disconnect anything.
Simple Fit and Secure Coupling: Multi-Fit Ball and Turn-Wheel Latch
The adjustable coupler fits 1-7/8", 2", or 50-mm hitch balls and locks down tight with a turn handwheel latch. This setup makes it quick to get a snug connection every time without tools or extra hardware. The design fits a standard 3" wide channel tongue with 3" spacing between mounting holes, making bolt-on installation straightforward for most trailers rated up to 6,000 lbs GTW and 600 lbs maximum tongue weight.
Built for the Long Haul: Corrosion-Resistant Zinc Finish and Steel Construction
A full zinc plating protects the steel body from rust and corrosion, whether used around freshwater ramps or on open roads. The actuator also includes a built-in shield that guards the solenoid valve from dirt and weather exposure. With this durable build and reliable protection, you can count on long-term performance through all conditions.
Added Safety When It Counts: Integrated Breakaway Kit
In case of an accidental disconnect, the included breakaway kit engages the trailer brakes automatically. It’s a simple but critical safety measure that keeps your trailer from rolling free if separation ever occurs—giving peace of mind every mile of the way.

The product itself is great. What I do not like is how it was packaged and that absolutely no instructions at all.
As for the packaging, the unit was put into a box with paper. The rain shield was thrown into the box and more paper added. Because the unit was not secured with more paper and it is somewhat heavy it rolled around in the box and bent and dented the rain shield. I do not need the rain cover but think you should improve the packing for this product.

etrailer.com is a great company to do business with, and they definitely get 5 stars from me. Great website (love the videos and things are easy to find) , great selections, good prices, fast delivery, great customer support, etc. Now, for the surge actuator...
I'll give the surge actuator 5 stars, too, but with some hesitation about a couple of minor things. First, let me say that I was absolutely thrilled with the performance of the actuator on its first road trip. We have a 5000 lb. combined boat and trailer weight, and while creeping down a very steep hill, just to see what things felt like, having the trailer behind me didn't feel any different than just driving my Yukon without the trailer. Also, stopping and then starting up from a stop sign was as smooth as silk -- no jerking or tugging feeling whatsoever. After pulling the trailer for about 30 minutes, I stopped and measured the temperature of the trailer wheels near the hubs, and they were at 75-80 degrees on a 60-degree day. Like I said, I was trilled, especially after previously dealing with an actuator that performed badly in all of the ways that this new one performed so well. That's why I'm giving the actuator 5 stars, but like I said, it's with some hesitation and here's why...
I'm not sure I'm a fan of the screw-type ball latch that's on the actuator. I wrestled with it for a long time before I finally figured out what was wrong and managed to get the latch onto the hitch ball. There's a small rectangular bracket on the bottom side of the latching mechanism, and it holds the hex head of the bolt that you're screwing down on when the latch is closing. The latch is spring loaded, so normally that little bracket is held in place where it needs to be, but if the spring is compressed, it's possible for the little rectangular bracket to get turned 90 degrees from where it should. And if that happens, you're not gonna get a 2" ball onto that actuator -- I tried and failed for a long time. The other thing that causes some hesitation is that that latch mechanism seems like it might not be quite as corrosion proof as I would hope. I've decided to spray it with WD-40 to see if that helps to keep it in good shape.
I'm including 3 photos with this review. One shows the little rectangular bracket that holds the bolt's hex head in its correct position, another shows what the latch should look like when it's fully opened, and the third shows the beginning signs of a little corrosion after the actuator has been outside for only a couple of weeks. We did launch the boat once in salt water, but I don't think the actuator got wet when we did it, so I think the slight corrosion is just from being outside in the rain, and not from salt water exposure.
Like I said, the actuator performed extremely well, so even with the minor criticisms, I'll still give it 5 stars. And etrailer definitely gets 5 stars!

I installed this new actuator, since my old one was leaking fluid. The installation was straightforward and I had no issues bleeding the new actuator. I had an issue with the ball retainer (it was a cast part, not a stamped part like my old unit) engaging and releasing from my 2" ball. I contacted etrailer and explained the issue and Tiffany immediately sent me a replacement kit for the ball retainer free of charge! I installed the kit, and it works perfectly! Thank you Tiffany and etrailer for helping and responding so quickly and professionally to my issue!

- Changing a Trailer From Electric Drum Brakes to Hydraulic Disc BrakesThe axle you purchased from us before is part # 35545E-ST-89. It uses inner bearing # L68149 and outer bearing # L44649. Since you already have electric drum brakes all you need to convert your trailer to disc is the brakes, brake lines, and an actuator. You didn't say whether you want hydraulic or electric over hydraulic brakes. The only difference in parts is which actuator you choose. If you want hydraulic surge brakes I recommend part # T4745720 as long as you have a 1-7/8 or 2...

- Solution for Needing Replacement Master Cylinder for DICO ActuatorThe DICO part number 17550 that you referenced actually matches a fixed coupler that we as Titan Weld-On Coupler part # T1755000. Most like you have a DICO model 60 actuator though. For a replacement master cylinder on your Dico Model 60 Actuator for drum brakes, you will need part # T4395100. This includes the master cylinder, gasket, orifice connector, hex bolt, lock washer, filler cap and cover. The part # T4745720 is an example of what a Model 60 actuator looks like.

Both options have the same weight rating, fit on a 3" wide channel tongue, and have mounting bolts holes with 3" on center distances between them. I'm not exactly sure what the mounting bolt hole locations were for your Atwood 82541 actuator so if the bolt hole locations...

If it's the axle capacity and a tandem axle trailer I recommend the Titan brake actuator, part # T4750820, that's rated for up to 12,500 pounds. If the trailer's maximum weight capacity is 5,200 pounds then instead I suggest part # T4745720. Both are zinc-plated to preven corrosion and include an electric lockout. If your axle isn't rated for 5,200 pounds let me know so I recommend the correct disc brakes. If they are...

- Electric Trailer Brakes Recommendation for a 1,400 lb Loaded TrailerFor that light of a trailer I would recommend you go with electric brakes. I would be concerned that the surge brakes would not activate properly, and since there is no adjustment for them you would be in a bind. One of the advantages to electric brakes is that they are able to be fine tuned easily and efficiently. To see everything you would need to install electric brakes on your trailer check out the FAQ article I attached on that subject. For a brake controller I would strongly recommend...
view full answer... - What Disc or Drum Brakes Should I Use for a 14' Utility Trailer? Hi Jeff, Disc brakes brake better than hydraulic drum brakes and perform better in wet conditions and with heavy trailers. They are a pricier option, but the performance is worth it. If you already have a surge brake actuator or are wanting to use one with your disc brakes, you'll need to make sure it's rated for a disc brake set up. Disc brakes require a higher pressure, 1.600 psi, versus drum brakes which only require 1,000 psi. If you don't have a surge brake actuator, the Titan Zinc...
view full answer... - PSI Rating for Titan Zinc-Plated Brake ActuatorSurge actuators like the Titan Zinc-Plated Brake Actuator # T4745720 mentioned in your question do not have an actual PSI rating. The disc unit will operate between 1,400 to 1,500, and with no residual back pressure. The actual PSI varies with weight of trailer, tire size, speed, braking ability of tow vehicle, and type & length of brake lines. Only electric over hydraulic actuators can be set to an exact PSI.
view full answer... - Titan Model 60 Actuator with Electric Reverse Lockout for Drum BrakesWe have the same coupler that works with drum brakes. It is Titan model 60, # T43397007K. For the reverse lockout feature you would simply install the Reverse Lockout Solenoid # T4748800 which will connect to the reverse light power function.
view full answer... - What is Needed to Replace Hydraulic Drum Brakes with Disc Brakes?You can definitely replace your current brakes with a disk brake set up. However, there are a few things that will need to be checked and upgraded to accomplish this task. First, you will need to determine which inner and outer bearings fit your spindle. As an example, the Kodiak Disc Brake Kit - 10" Hub/Rotor - 5 on 4-1/2 - Dacromet - 3,500 lbs # K2HR35D is designed to fit spindles with an # L68149 inner bearing and # L44649 outer bearing on a 3,500 pound axle. This will also use a 5...
view full answer... - Recommended Trailer Braking System For 30 Foot Pontoon Trailer With Tandem AxleWith a 6000 lb capacity on your pontoon trailer and 13 inch wheels, you most likely have 3500 lb axles. For this, you will want Electric Trailer Brake Assembly - Self-Adjusting - 10" - Right Hand - 3,500 lbs # AKEBRK-35R-SA and the left side assembly # AKEBRK-35L-SA. The mounting hardware kit is # BIK-00. You will want to run 10 gauge wire to these brake assemblies and it can be purchased by the foot # 10-2-1. To finish your wiring, I recommend the 7-Way Molded Trailer Plug with Junction...
view full answer... - Bleeding a Manual Actuator like the Titan Zinc-Plated Brake Actuator w/ Electric LockoutYes you are exactly right. You want to bleed the Titan Zinc-Plated Brake Actuator w/ Electric Lockout part # T4745720 after you have the lines installed and it can be bled just like you do normal brakes. You can use a power bleeder or the way I prefer by hooking the safety chains together and using a lever to manually operate or push the actuator. Either way is effective just ensure you do not have any power going to the lockout solenoid so the fluid will flow freely.
view full answer... - Disc Brakes Do Not Appear To Be Working Properly On Tandem Boat Trailer With Surge CouplerIt sounds like you have been testing this system quite a lot. There are several steps you can follow to trace where the problem is. First, you did not say if this is a new brake system with disc brakes and was upgraded from drum brakes. If that is the case, the actuator should have been upgraded as well. The disc brakes require a higher amount of pressure to work than the drum brakes. If you have a disc brake actuator you can move on. Next, check the calipers, and rotors for signs of...
view full answer... - Surge Brake and Electric Brake Controller CompatibilityYou will not have any compatibility issues between the brake controller and the surge actuator. The reason is because the brake controller will not be used in any way with the surge actuator. The brake output circuit will basically dead-end and not go anywhere on your trailer so you would not have to worry about it in any way. The trailer basically will do all the braking by itself between the surge actuator and the disc brakes. You would not need to remove any fuses either to prevent...

It does not have a reverse lock out solenoid so you would need to add that with the part # T4748800.

This actuator is designed for working with disc brakes and will work with trailers up to 7000-lbs. The only other option available for disc brakes is the Titan Zinc-Plated Brake Actuator...

For your brake actuating coupler, I recommend the Titan Zinc-Plated, Leverlock Brake Actuator w/ Electric Lockout - Disc - Adjustable Ball - 6,000 lbs # T4745720. Disc brakes require more pressure from the master cylinder, so an upgrade is necessary for this application....
view full answer... - Suitable Hydraulic Coupler for Kodiak Disc Brake Kit Part # K2R526SThe Titan Brake Actuator with Electric Lock Out, part # T4745720 would work well with the Kodiak Disk Brake Kit you referenced. The actuator, which carries a 6000 lb capacity, features an adjustable coupler which accommodates 1-7/8, 2 inch and 50mm trailer balls. The included electric reverse lock out solenoid is protected from damage by an included cover.

Let's see if we can get this working as it should Erwin. The attaching mechanism on the Titan Model 60 Multi-Fit Actuator can sometimes jam if the latch is adjusted too tightly for the hitch ball size. When this happens, the ball wedges into the fork and the mechanism binds. Cleaning out any residue, applying a light lubricant to the pivot points, and cycling the latch several times with the correct ball size usually smooths the action. If it still binds, slightly loosening the adjustment nut will allow the ball to seat securely without excess pressure. Please let me know if this fixes the issue.
