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.

Electric reverse lockout with solenoid is automatically activated when the tow vehicle is shifted into reverse. To use this feature, you must have a 5-pole flat, 6-way round or 7-pole wiring harness.

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! 807518

Ask the Experts about this Titan Brake Actuator

  • Disc Brake Actuator with Electric Lockout for Magic Tilt Trailer
    For your Magic-Tilt tandem axle boat trailer with disc brakes and a straight tongue I recommend Titan Disc Brake Actuator Coupler # T4745720. This 6K bolt-on coupler has an electric lockout and I like it because it features a multi-ball fit so it will work with 1-7/8-inch, 2-inch and 2-5/16-inch hitch balls. You can refer to the video for more information. If you use only a 2-inch hitch ball you could instead use Demco 6K Coupler # DM8605101 which also has the electric lockout and uses...

  • Hardware Needed to Install the Titan Model 60 Actuator
    You would want to use a Grade 5 Bolt that is about 4 inches long that can fit a 7/8 of an inch hole. I spoke to Titan and they recommend either a 3/4 inch hole or a 7/8 inch hole. I attached a template for mounting the Titan Actuator part # T4339720 for you to check out.

  • Where is Voltage Coming From When Using Actuator With Electric Lockout for Hydraulic Disc Brakes
    When using an actuator like the Titan Zinc-Plated Brake Actuator w/ Electric Lockout - Disc # T4745720, the voltage for the solenoid is coming from the reverse light circuit. It will supply voltage only when the reverse light is on when using a 5-way connector. If you need a 5-way you can use the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter # 20036, and I have added a link to a video install for you to check out as well. I have added a link to a help article on trailer wiring you...

  • A-Frame Surge Brake Coupler Recommendation
    Your question came in blank, but judging by the coupler part # T4745720 that you referenced and the picture you submitted it would appear as if you are looking for a surge brake actuator for an A-frame trailer. Which for that you would want the Titan Actuator part # T2492800. I attached a review video plus a link to a page that has all of the other a-frame surge brake couplers we carry that would fit.

  • Titan Model 60 Actuator with Electric Reverse Lockout for Drum Brakes
    We 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.

  • Recommended Surge Brake Coupler For Disc Brakes With Electric Lockout
    The best replacement for your coupler for disc brakes is the Titan Zinc-Plated, Leverlock Brake Actuator w/ Electric Lockout - Disc - Adjustable Ball - 6,000 lbs # T4745720. This has the electric lockout built in for free backing so you need to only shift into reverse for this lockout to engage and allow you to backup without trailer brakes. It has a master cylinder designed for disc brakes that require a much higher pressure than drum brakes. The Atwood Actuator you asked about is...

  • Parts Needed to Upgrade Drum Brakes on Tandem Axle Boat Trailer To Disc Brakes
    Assuming that you choose the correct rotor that matches your wheel bearing numbers and wheel bolt pattern, you would need to choose a hydraulic actuator that is appropriate for disc brakes like the Titan # T4745720, Due to the fact that the calipers move, you would need to provide a brake like kit that has a flexible connection at the caliper like part # 9579-2 which will work with disc brakes. We actually have a FAQ article that explains what is needed to upgrade your brakes. To see...

  • PSI Rating for Titan Zinc-Plated Brake Actuator
    Surge 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.

  • Can Trail-Rite Trailer Have Actuator Replaced with T4745700
    As long as your trailer has a 3 inch channel the Titan brake actuator part # T4745720 would work well for activating one disk brake axle. It does not have a reverse lock out solenoid so you would need to add that with the part # T4748800.

  • Recommended 6000 lb Surge Brake Actuator For Disc Brakes
    Your current actuator, similar to the Atwood Brake Actuator w/ Manual Lockout - Drum Brakes, will not work with disc brakes. Disc brakes require much more pressure than drum brakes so you need a different actuator to handle that application. For a compatible actuator, I recommend the Titan Zinc-Plated, Leverlock Brake Actuator - Disc - Adjustable Ball - Bolt On - 6,000 lbs # T4745720. This can be used with standard brake lines for drum or disc like # 24TA-BLKIT or # 18SI-BLKIT.

  • Surge Brake and Electric Brake Controller Compatibility
    You 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...

  • Surge Brake Actuator Recommendation for a Boat and Trailer that Weigh 2,200 lbs
    A 6,000 lb capacity actuator like the part # T4745720 would work great with your boat and trailer that weighs a total of 2,200 lbs. This is a multi-fit coupler that should work with virtually any hitch ball size. Check out the review video I attached as well.

  • Can You Manually Lockout an Electric Reverse Lockout Brake Coupler
    I have a solution for you if you have drum brakes, but I spoke with my contact at Titan and he did not have a recommended way to manually lock out a trailer brake actuator that has an electric reverse lockout. The best thing you can do is get some free backing trailer brakes. These brakes allow your trailer to back up without activating the brakes, even if your trailer does not have a reverse lockout. Since I do not know what size brakes you have I attached a page that has all of the...

  • Electric Trailer Brakes Recommendation for a 1,400 lb Loaded Trailer
    For 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...

  • Disc Brake Surge Coupler for a Tow Dolly
    Your best pick is the Titan Zinc-Plated Actuator, part # T4745720, which includes an electric backup lockout and compatibility with disc brakes. This kit will bolt onto your tow dolly and is rated for up to 6000 pounds. I did check into your owner's manual and it looks like the 2015 Jeep Wrangler two door variants are only rated to tow 2000 pounds, and I'd recommend using another tow vehicle if possible.

  • Disc Brakes Do Not Appear To Be Working Properly On Tandem Boat Trailer With Surge Coupler
    It 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...

    To give you your upgraded brake system, I recommend using the Kodiak Disc Brake Kit - 10" Rotor - 5 on 4-1/2 - Dacromet and KodaGuard - 3,500 lbs # K2R35DKG which will install right over your current hubs. I also recommend using the Kodiak Hydraulic Brake Line Kit - Single Axle - 18' # 18SI-BLKIT which will give you flexibility for your brake calipers and folding coupler connection. Then you can use the Titan Zinc-Plated Brake Actuator w/ Electric Lockout - Disc - Multi-Fit Ball - Bolt...

  • Recommended Replacement Actuator for Atwood 85778

  • Replacement Surge Brake Actuator Recommendations for Atwood 82541
    I recommend either using the Demco 6K # DM8605101 if you want a standard actuator that fits a 2" hitch ball or the Titan 6K # T4745720 if you like the option of the coupler fitting with either a 1-7/8", 2", or 50 mm hitch ball. 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...

  • Changing a Trailer From Electric Drum Brakes to Hydraulic Disc Brakes
    The axle you purchased from us before is part # 35545E-ST-EZ-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...

  • Suitable Hydraulic Coupler for Kodiak Disc Brake Kit Part # K2R526S
    The 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.

  • Recommended Replacement Surge Brake Actuator and Disc Brakes for Boat Trailer
    Is the trailer's GVWR 5,200 pounds or is that the axle capacity? 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...

  • Recommended Surge Brake Actuating Coupler For Disc Brakes
    The surge that you have now is rated for drum brakes, and you would need to get one rated for disc brakes to upgrade to the Kodiak Disc Brake Kit - 12" Hub/Rotor - 6 on 5-1/2 - Dacromet - 5,200 lbs to 6,000 lbs # K2HR526D. 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....
