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.

Video Transcript for Titan Brake Actuator - Surge Brake Actuator - T4745720 Review

Take a look at the Titan bolt on zinc plated brake actuator with the electric lock out for disc brakes. This is a multi fit ball design, and it has a 6000 pound weight capacity. Now this hydraulic actuator will synchronize your trailer brakes with your tow vehicle brakes. This is made of a durable steel construction, has a zinc plating to provide extra corrosion resistance. It is an easily adjustable design a multi fit ball design. It will fit 1 7/8 inch, 2 inches, and 50 milometers. hitch balls, and you just adjust it to fit witch one by using this hand wheel right here.

Push the lever down and you can loosen this or tighten it depending what you need. Once you let the lever go and then turn it you can see it will lock it into that position. Breakaway kit right up here is included. The nice thing on this one it does have the electric reverse lock out feature right back here if you can see the solenoid that's attached to the back here that the brake line will go into to. This feature will actually let you back up without actuating your trailer brakes. The solenoid valve you notice has the two black wires, they will need to be connected.

One will go to the ground, the other goes to the reverse light circuit, and they are both black wires so either wire for either function, and when it's all wired up you basically put your vehicle in reverse, it'll automatically the solenoid will shut off the flow of the brake fluid to the cylinder. To use this feature you must have a five pole flat, 6 way round, or a 7 pole wiring harness. If you notice this has a nice built in zinc plated shield to protect the solenoid from the elements and from any damage so somebody doesn't step on it and bust it or break it. This is a bolt on instillation, if you notice the holes on the side. It is your standard 3in center to center measurement. This part is made in the USA, and again the specks on this, the application is for disc brakes. The ball size it fits is 1 7/8 inches, 2 inches, or 50 milometers.

Mounting is a 3 inch wide channel tone. Let me just put it this way and I'll be able to measure and show you. There's your 3 inches wide that will fit on the channel tone. Weight capacity again is 6000 pounds, the max of the tone weight is 600 pounds. That should do it on the review of the Titan bolt on zinc plated brake actuator with the electric lock out for disc brakes. Multi fit ball design, and a 6000 pound weight capacity..

Ask the Experts about this Titan Brake Actuator

  • Titan Model 60 Actuator with Electric Reverse Lockout for Drum Brakes
    We have the same coupler that works with drum brakes and that also has the electric reverse lockout feature. It is Titan model 60, # T4339720. I have included a link to a video review of this coupler for 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.

  • 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.

  • 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.

  • 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.

  • 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...

  • 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...

  • 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...

  • 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...

  • 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.

  • 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...

  • 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.

  • 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...

  • 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...

  • Recommended Trailer Brakes For Shorelander Tandem Axle Boat Trailer
    Electric drum brakes work just fine on boat trailers, but I do recommend disconnecting the trailer from the vehicle before backing into the water to protect your vehicle. The electric brake assemblies are easier to install and will allow you to keep costs down, but hydraulic brakes are a better option for boat trailers. There are options other than an Electric Over Hydraulic system. For your application, I recommend you consider the Titan Disc Brake Kit and Actuator w/ Electric Lockout...

  • 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...

  • What Type of Coupler is Supplied in Titan Disc Brake Kit with Leverlock Actuator # T4843200
    The Titan Disc Brake Kit and Leverlock Actuator # T4843200 that you recently ordered (thank you) does include a leverlock actuator. This particular complete disc brake kit is not supplied with a multi-fit coupler. The supplied leverlock actuator has an adjustable coupler that will work with 1-7/8-inch, 2-inch or 50-mm hitch balls. It will work with your 2-inch hitch ball. Multi-fit couplers are available as separate parts such as # T4745720 from Titan which is shown in the linked video.

  • 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....

  • 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...
