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.

Video Transcript for Titan Zinc-Plated Leverlock Brake Actuator Installation

Today we're gonna look at, and show you how to install the Titan zinc plated lever lock brake actuator. This was designed for use on disc brakes, and it'll work for inch and 7/8, or 2 inch balls with the adjustability. It's a bolt on design with a 7,000 pound capacity. The part number is T47154007K.Now, the actuator is basically gonna act like your brake pedal on your boat trailer. So as we hit the brakes in our truck, it's gonna give resistance this way, and the boat's gonna try to push forward. So when that happens, if you take a look ...

see how that slides in That sliding motion is gonna work our master cylinder internally, and push that pressure through to our brakes. This is gonna give us a great advantage in braking, in that we're not worried about electronics, we're not worried about brake controllers, that's all gonna happen right here. You get the benefit of disk brakes out of it, and as that slides back in them, we get the pressure.So, it's a very proportional type system. Under light braking it's only gonna lightly move, so we're gonna get lighter braking force. Under the more emergency situations where we really gotta get on the brakes, this is gonna push together much more quickly and rapidly, giving us higher braking force on our trailer.Now, if for some reason the trailer we're to become disconnected from your truck, the lever here is gonna lock the system out, and bring your trailer safely to a stop.

So, this is pull. That's gonna engage the cylinder in there, applying the brakes for us.Now, with the full zinc coating we have on the actuator, this is gonna do a very good job of resisting corrosion.Now, we're gonna get our actuator set into place. We're just gonna use a temporary position to start, so we can make our connections on that backside. But, what we'll have are the two holes here and here, and if you've already got a braking system, or a hydraulic braking system, you're probably already gonna have those two holes to attach it to. If not, they're gonna be half inch holes, and use a half inch bolt.

You wanna be at least 4 inches long, 4 1/4, 4 1/2 would also be fine. Place that down and on. Like I said, I'm just gonna put it here temporarily. Once we get our connections made, we'll slide it back and line up both the holes and get it attached.Now, between our actuator and the line that provides fluid to our calipers, we're doing an electric lockout. So basically, this is gonna be connected to ground on one side ...

we'll show you how to do that . and to your reverse wire coming from your seven pole, or five pole, six pole, whatever you've got, on the other side. It's gonna act as a solenoid. So, as your vehicle's backing up, it's gonna cut off that pressure, or that brake fluid from locking up the brakes. Basically, this is important when you're backing up a hill, and you want to be able to have your trailer wheels turn freely. This prevents that pressure from being sent back. Otherwise, when you started to back up a hill, as the actuator gets compressed, it's gonna apply the brakes. It's gonna make it difficult to back up.Now, the solenoid is designed to replace the thread adapter that we have here on the back of the actuator. So we're just gonna use a half inch wrench, and we're gonna get that removed. Basically the actuator's designed to work with or without an electric lockout. So, by taking this out, we'll be able to threat this in. That way it'll be set up for that lockout procedure when we hit reverse.And we wanna get that secured to our actuator, and we're gonna use that big nut there. That's a 15/16 inch wrench. Now we'll take the flexible brake line hose . you'll have a shorter one from your kit. Remember, we've kind of lengthened ours a little bit just to make up for the length of the tongue. And we're gonna get that secured down.Now, as you start it, also hold this one with a wrench, that way we don't have to worry about this turning on us. For this, you wanna use a 9/16, and then for this we're gonna stay with the 3/8.Now, for the wiring side, I'm gonna extend one of the wires slightly. It really doesn't matter which one. I'm gonna use a piece of 16 gauge wire. This is gonna allow us to get it to the reverse signal on the plug coming from our truck. To connect the two together I'm gonna use a heat shrink butt connector, part number is DW05744. And, if you don't have wire, that part number is 16-1-1.Let me get that crimped down. Now, we're gonna use a heat source to get this shrinked. You can use a heat gun, you can use a mini torch, or just a lighter. The key is not to overheat it, so I'm gonna give it some gentle heat, and you'll see it start to shrink down, just like that.Now, once it's fully shrank, you notice the wire looks like it's much bigger, and then there's just a little clear gel that comes out of the end. Now, the other wire will act as our ground, so we're gonna strip that back. I aways like to twist the wire, give it something good to hold onto, and we're gonna place it on a ring terminal. Gonna crimp that down, and we just have to attach this to the tongue. So, when we hit reverse, the signal comes through here. The solenoid is gonna close, not allowing the fluid to pass by, and then, because we've got it grounded out, it's gonna work for us.I'm gonna place that right here, so it still would be accessible, but as we slide this back most of that wiring will go inside there. We use a number 12 self-tapping screw to make that connection. Just like that. Got our connections made, and now it's just slide the actuator back, and get our bolts put in.With those through, we're gonna place a couple of nylon lock nuts on the other side. Seems like the 4 inch bolts really work out well, and they give us just enough bolt length there to get those nylon threads engaged, and get everything nice and secure.Now, with half inch bolts, you'll use a 3/4 inch, or a 19 millimeter wrench and socket. They're the same size. Now we'll get our bolts torqued down.With our actuator installed, we've got all of our connections made all the way throughout. It's time to add fluid into the reservoir here on top. So, we're gonna open that up. Now, the brake fluid you pick, you wanna make sure that you just opened it, that you just opened the seal. Brake fluid that sits around for a long time, it draws moisture into it and it reduces it's effectiveness. So, we want a fresh pint of brake fluid here. Generally it takes two or three pints to get the entire system flushed. Some a little bit more, some a little bit less. We're just gonna top it off, cap it back up, and we'll go through the bleeding process.Now, I cannot stress to you enough the importance of keeping fluid in this reservoir. If you are bleeding the brakes, pumping fluid through it, and this runs dry, well then you're just gonna pump air into the system, and then you have to go through the whole thing again. So, be sure every one or two times that you have someone hold the lever, which we'll show you here in just a second, and open that up, that you take a look in there to make sure you've got the pressure, or at least the fluid you need to keep it pressurized.Now, something I like about this coupler that we don't see on all of the couplers out there on the market is right here you can see the head of a screw, or a bolt that comes out with a lock nut on it. Simply by using a screw driver, we're able to go to the hole in the coupler, we can get that in front, and we can use that to pump our fluid. That's gonna generate the pressure that we need to get our fluid all the way back through our lines to our calipers. So, what we do, pump it up a little bit here, just to get everything primed, then we're gonna have somebody hold this. As they're holding it we're gonna open up our bleeder screws and start letting air out of the system.You'll notice here as we pump that, the air coming up in the reservoir. So, that slowly getting fluid down into our master cylinder, that'll eventually work into our lines. So we're just gonna do this until we don't see the air here, and that it's being pushed all the way back and through the system.You can kinda see at this point we have very little, if any, air coming out at all, so that means we're gonna be primed here. Now it's time to start going to the back. Now remember, we're gonna top off this fluid every chance we get. Keep that full.Now, for bleeding the system, we're gonna use the top bleeder screw on each side. That's why there's on on the bottom and one on the top, so regardless of which side the caliper goes on, we always wanna use the upper one. We got the rubber cap, we're gonna take that off, and we wanna turn the smaller portion here. For that you wanna us a 5/16 lefty loosey, righty tighty, but you need something to catch the fluid. See here, a very sophisticated device that we've come up with. Basically it's gonna be a rubber hose, goes in the top of a water bottle. So we'll place this over the top of that bleeder. We'll go ahead and have him pump up the brakes. Once they've got that pressure held, we wanna open this, and by opening it we're gonna release the pressure inside there. It gives us a little bit of air that comes out, and we just need to continue this process until we get rid of all the air that's coming through and we just have pure fluid.Okay, go ahead.You see on the bottom of our bottle here we've got just a little bit of fluid. Let's watch as we break this open. See those bubbles forming That's what we're getting rid of. So each one of those bubbles indicates air that's coming out of our line. Okay, I'm gonna tighten it back up. Go ahead.Now, a couple of tips for bleeding the system. Start with the one that's furthest away from the actuator. Basically, if we drew a line they'd be the same distance, but this one has more brake line, so we're gonna start here. And you can see we've still got air coming out, but we're also starting to get a little bit of fluid. Just wanna make sure we can do this three or four times and not have any air come out. At that point you're pretty much sure that this line's void of any air, and we'll go over to the other one.Alright, looks like at this point, pure fluid coming out, so we'll just move over to the other side, and we'll do the same thing there. Now, that should take us a lot less time because we don't have to work it all the way from the actuator through all the lines. Once you're done with the side, put that bleeder cap back on, just to keep it free of debris.Once we've got this system bled, we wanna refill our reservoir and make sure we've got plenty of fluid there, and we're gonna do the same thing we did before. We're gonna apply pressure here, and then we're gonna check each of our connection points and make sure we don't have any leaks. We wanna check underneath the front of our solenoid there to make sure we don't have any fluid there. If you connected your hose just like we did, but we used a longer one, you wanna check that connection. In this case we'd have to use a flashlight. We'll check in there in just a second. We're gonna check each of the fittings here at the T. You can see two of those are nice and dry. We're gonna check our hard line connection to our flexible line, and we'll check the point at which that flexible line goes into the caliper. As long as everything there is dry with some pressure held on it from up front, should be in really good shape.Now we can check out, and make sure everything's working, which we know it is, but it's good to do. What we're gonna do is rotate our tire here. We'll get it spinning, and we'll have somebody manually activate the brakes for us up there. You see, it comes to a nice stop.And that's gonna complete our look at the Titan zinc plated lever lock brake actuator, part number T47154007K.

The coupler was used to replace the identical existing unit on my car trailer. On the old unit, the master cylinder had seized after about 15 years of operation. Replacing the entire unit rather than replacing or rebuilding the master cylinder was the most cost effective solution. The new unit was a direct, bolt-on replacement for the old. 548093

The item appears to be in good shape but there were ZERO installation instructions. Also there was no mention that I also had to order a reverse lock-out solenoid for an additional fee .

  • Replacement 7,000 lb for LP7000 Surge Brake Actuator
  • We definitely have surge brake actuators that will work for you, but the ones we carry are mounted on top of your trailer's channel tongue and you will need to drill new holes in order to mount them. The Titan actuators are premium quality and the correct 7,000 lb actuator that works with a 2" hitch ball is going to depend on if you have drum brakes or disc brakes. For drum brakes you will need the Titan Zinc-Plated, Leverlock Brake Actuator - Drum # T43329007K. For disc brakes you...

  • Difference Between Model 60 Surge Trailer Brake Actuators that Fit Disc and Drum Brakes
  • Trailer drum and disc brakes require different psi ratings so that's why the part # T47154007K can only be used on disc brakes. Drums usually need 1,000 psi whereas disc needs 1,600 psi. For a version of this coupler that is designed for drum brakes you'd want the part # T43329007K. Or you can change out the master cylinders to fit the application. For a Model 60 actuator like this the part # T4820000 is for disc and part # T4395100 is for drum. To convert either actuator would only...

  • Replacement Actuator Recommendation for Atwood
  • Atwood actuators are no longer made and what you'll need to do is have yours removed and a better one installed in it's place. Nearly every time we get a question about troubleshooting an actuator or needing replacement parts it's an Atwood in question so going to a different setup will long term be your best option. For a Titan actuator for disc brakes we have the part # T47154007K which would be a great option.

  • How to Switch Titan Model 60 Drum Brake Actuator to Disc Brake Actuator
  • Actuators for drum brakes and disc brakes require different psi ratings so you would not be able to use your 7,000 lb rated Titan Zinc-Plated Brake Actuator - Drum # T4339720 with your trailer that has disc brakes, but you don't need to get an entirely new 7,000 lb rated Titan Actuator - Disc # T47154007K either. Instead, all you need to do is switch our the master cylinder on your drum brake actuator for the disc brake application; so all you need to do is add the Replacement Master...

  • Is a Double Flare Tool Needed to Attach Brake Line to Titan Actuator
  • You would not need to use a double flare tool to create a bubble flare to install brake lines to a Titan coupler like part # T47154007K. Standard threaded fittings that are 3/16 inch in diameter like what the part # DMSB520 has would be all that you'd need.
