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 - T4747220 Review

Today we're going to review part number T4747220. This is the Titan zinc-plated break actuator, with the electric lockout for disc breaks. Has an 8,000-pound weight capacity. Now this hydrolic actuator will syncronize your trailer breaks with your tow vehicle breaks. It does feature the electric reverse lockout. If I swing it around here, you'll see the solonoid valve, right there.

This will let you back up without actuating the trailer breaks. Also has this built-in shield that will help protect that solonoid valve from the elements, and also from getting damaged by running into it. This actuator does have a unique roller design. There's a roller right up here, and one down here. This type of design witll reduce resistance during telescoping of this front part of the actuator.

Helps create a straight-line movement. Made of a sturdy, durable steel construction. It will help resist bending and any jackknife situations. It is a heavy-duty coupler. Has a zinc plating, which will provide corrosion resistance, and it is a bolt-on installation. You can see here, at the bottom, has the holes in it.

What you would do, this channel right here, . This is a 3-inch wide measurement. This fit's designed to fit on the 3-inch-wide channel tongue of your trailer. Then you would just bolt it, using these existing holes, here. They should match up to holes on your trailer.

If they don't, you would need to drill holes, to attach this. Also, it includes this break-away kit, which is included. You can see, this is a steel cable, attached one end to the handle on top of the actuator. The other end is attached to a steel hook. Now this is a safety feature. It is required on trailers with hydrolic breaks. Basically, what you would do, when this is installed on the trailer and you attach it to a hitch ball on a tow vehicle, then you hook your safety chains from the trailer to the tow vehicle, also; what you'll want to do is, right where you hook your safety chains, you want to attach this hook from the break-away kit. What this will do is, in a situation where this would come detached from the hitch ball, normally the safety chains would hold it into place, until you could pull over. What would happen if the safety chains weren't hooked, or if they did come free, what would happen is, this safety cable is a little bit longer than those safety chains; what happens if the safety chains don't work, it would pull this cable, which would activate this handle, move this handle forward, and that would activate a rod which would go into the master cylinder and apply the break pressure to the trailer, and lock up the breaks. By chance, if this come detached, and the safety chains didn't work out, this would come into play, and lock up the breaks, to keep the trailer from running away. Also on top of this actuator, you probably notice, there's this plastic cap that you can just unscrew. That will give you access to the master cylinder to put fluid in, and also to periodically check the fluid level. Now this does also have the lever in front with the ring on it. This is what you would do to open up, to hook up to a hitch ball. Just pull up on that ring, which would unhook it right there. That will allow you to flip open this lever. Then with it open like that, it's ready to attach to a hitch ball. Basically, what happens is, right in here, down in there, there's a wedge that when you activate it, when you put it on the hitch bolt and then push that lever forward, until it locks into place, you'll see in the inside, that wedge will move up against the hitch ball and hold it. I'm going to open it, here. I'm going to show you. I got an example right here of a 2-5/16 hitch ball size that this actuator would fit on. When you attach it, it would slide right up in there. Then with it up in there, you let that lever down, you hear it lock into place. That wedge came down, and it's locked onto that hitch ball, so it's not going to go anywhere. Then when you want to detatch it from the hitch ball, you just lift up on that ring, and then pull that lever. That will move that out of the way, and your hitch ball will come right out. Very simple hookup. The application for this actuator is disc breaks only. Again, I mentioned it fits just the 2-5/16 ball diameter. Does have a capacity of 8,000 pounds, a maximum tongue weight of 100 pounds. Just to show you the underneath, real quick, here's where the hitch ball would attach, right in this section, here. You can't see it, but there's actually a . looks like a shock absorber, but it's an actuator that would be used when this is compressed, to apply the breaks. You see the master cylinder, right here. Again, we mentioned the solonoid valve here, for the electric lockout. This is actually installed in the back of the master cylinder. Then your break line would install into the solonoid valve. Basically, what happens, just briefly, to tell you, on a surge break system, what this is, this section here, will slide on those rollers I mentioned. What happens is, when you apply the breaks in your tow vehicle, . This is hooked to the tow vehicle; decelleration will occur, and the momentum and weight of the trailer will move it toward the rear of the tow vehicle. What happens is, it compresses that, and when it does that, that actuator, which is right down in here, underneath here, it will telescope, and it will apply force to this master cylinder, which in turn, will supply that hydrolic pressure to engage the trailer breaks. This is basically how the breaks would be applied on a surge break system. Again, the selectric reverse lockout, what this will do is, this will allow you to back up without activating your trailer break. If you need to back up with the trailer hooked up, you don't want to go backwards and have the breaks be applied. This reverse lockout basically, what you would do, you'll see it has two wires to it. One wire is a ground; the other is attached to the reverse light circuit on your tow vehicle. Once it's wired up, then when you put the tow vehicle in reverse, it will send an electric current to here, which will then block the break fluid from going to your break lines. That's how it will keep your trailer breaks from being applied, when you go into reverse. To use this electric lockout feature, you do have to have either a 5-pole flat, a 6-way round, or a 7-way wiring harness on your tow vehicle. When you do wire this, the wires, it doesn't matter which one's which; they're both black wires. You just have to hook one to the ground, and one to the reverse light circuit. That should do it for a review of part number T4747220, the Titan zinc-plated break actuator with the electric lockout for disc breaks. .

Not sure of actual product performance yet. But you guys really need to add a small instructional sheet. Wasted half an hour trying to figure out fittings before I finally figured out that since reverse solenoid was not attached it replaced the fitting already on the cylinder. Then after I had it together I saw that the longer shield that was included loose for the reverse lockout solenoid could NOT be put on without removing short shield which could not be removed without taking off the brake lines that I had just installed. Half sheet of paper with 2 or 3 sentences is all you would need to include. 432033

Works fine, But there are many times that a bypass or lockout is needed.

The coupler itself met expectations and is functioning perfectly. However, there are three things I would like to report that would make the installation easier. First, some written instructions would be helpful. I started to replace the nut that goes to the backup actuator. I recall a review and looked at the video. No nut replacement, just screw in the actuator. The nut is just used for shipping. The product is excellent and my identical Titan lasted over 10 years of salt water use. Glad to see that the quality has not decreased. Will buy again from etrailer. 524362

The coupler itself met expectations and is functioning perfectly. However, there are three things I would like to report that would make the installation easier. First, some written instructions would be helpful. There was NO documentation that came with this major item. Next, I was unable to attach the solenoid cutoff for the coupler and determined the solenoid was a different thread size than the coupler's reservoir fitting. I spent extra time and two trips to the hardware store to correct this only to discover that the fitting on the reservoir needed to be removed AND REPLACED with the solenoid connection. The last item relates to the protective cover for the solenoid. A separate part is included that protects the solenoid and its fitting but nothing tells you that this needs to be installed in place of the shorter cover supplied on the coupler. One additional point is the lack of instructions to properly bleed the braking system. It is a little tricky on this item and knowing the correct process would have been helpful instead of relying on internet searches to find help. 503985

Do you have a question about this Brake Actuator?


  • Parts Needed to Add Disc Brakes to Drum Brake Trailer
  • If you have Atwood surge coupler # 83010 and you want to convert the trailer from drum brakes to disc brakes on one axle you will need to either replace the coupler or replace the master cylinder inside it with one that delivers the higher psi pressure required by disc brakes. Disc brakes need psi pressure in the 1500-1600-psi range so a new 8K-rated actuator/coupler like # T4747220 is needed. If the trailer has two 3500-lb axles (which would be expected if it has the 8K-rated Atwood...

  • Recommended Brake Actuator With Lock Out for 7000 LBS. Boat Trailer
  • The standard tongue weight on a trailer is approximately 10-15 percent of the GTW. On a boat trailer it generally stays at 10 percent because most of the weight of a boat is towards the back end of the trailer, reducing the need for more tongue weight. This is why all of our couplers have a tongue weight of 10 percent of the GTW. If you'd like to be more definite in your tongue weight, you can always use a scale like the Sherline Trailer Tongue Weight Scale # 5780. The Titan Zinc-Plated...

  • Can An Electric Reverse Lockout Solenoid Be Submerged?
  • An electric reverse lockout solenoid like found on the Titan Zinc-Plated Brake Actuator w/ Electric Lockout # T4747220 should not be submerged while connected to your 7-way. Electricity and water are not a good combination, so keeping your reverse lockout solenoid connected at the point of submersion is not a good idea as it could short out your entire trailer connection on your vehicle. What we recommend is backing your trailer up to that point with the connection, but stopping to...

  • Is an Electric Reverse Lock Out Required for Backing Up a Trailer with Surge Brakes
  • There are 3 ways to allow a trailer with surge brakes to back up. There can be an electric reverse lockout, a manual lockout, or you can use free-backing brake assemblies if the brakes are drums. The easiest and most-preferred method is the electric reverse lockout like what comes on the Titan Model 6 part # T4747220. Or for just the lockout you would want the part # T4748800. I also attached a link to a page that has all of the free backing brakes we offer.

If there were a short somewhere on the trailer power could be reaching the reverse lockout solenoid when it is not supposed to. This could happen if the trailer's 12V auxiliary power circuit were shorted to the frame. You can try disconnecting the wiring for the reverse lockout solenoid to see if the coupler will engage (compress) when you back up. Other...
