Titan Brake Actuator - Surge Brake Actuator - T4839000 Review


Today we're taking a look at the Swing Away Actuator with a manual lock-out. Now this is a hydraulic actuator, and it's designed to synchronize your trailer brakes with your tow vehicle brakes. So when you apply the brakes in your tow vehicle, deceleration occurs and the momentum actually pushes your trailer towards the rear of your vehicle.With surge brake systems, your actuator is triggered as your trailer moves forward while the tow vehicle slows, so the actuator, which is internally here, it telescopes, which then applies force to a master cylinder internally, which then supplies the necessary hydraulic pressure to engage the trailer's brakes.So it's a really nice design, it's easy to use. One of the unique features about this particular one is it features a swing-away design which allows you to save space, so it has a space-saving swing-away design. So right here we have a pivot point, for the actuator. This whole portion will actually pivot back, creating a shorter tunneling for easier storage.

The fold-away portion can swing either way, you might just have to reorient the bracket. But right now it's set up to where all you got to do is pull a clip, pull the pin and then whatever side the bolt's on, that's going to be your pivot point, so this would actually swing this way.So it's a nice design of the unit. I also want to point out that your installation hardware's included. You can see here that we got the bolts already on there. I just got them hanging loose.

But your six bolts and hardware, everything you need for your install's included, as far as your attachment hardware. It also features the manual reverse lock-out, so it's going to let you reverse without actuating your trailer's brakes. Comes with a easy to use lever, so that just inserts in that area there. It can also be inserted on the other side here. So the easy to use lever activates the lock-out and free-backing brakes are not required, so this works with uniservo and duoservo brakes.It also has your break-away kit, so this attaches to your tow vehicle.

In the event where your vehicle and trailer separate, the vehicle would pull on this cable, which would activate the trailer's brakes, bringing it to an eventual safe stop. Bolt-on installation, it's designed for hydraulic drum brakes. Fits a two inch hip ball. I like this latch mechanism, so you have your pin located right here, it's tethered on there so you don't worry about misplacing that or losing that. To open this up you just slide that over, lift up.

That opens the socket. Drop it onto a two inch ball. Now all you got to do is push that down. It engages, and then reinsert your pin. And that's all there is to it. So it's easy to use.The pivot length. I took a measurement from this point here to the very end, or to the very front. Got a measurement of 22 and three-eighths inches. The mounting, it's designed to mount to a three inch by five inch channel tongue, but after using this on a three inch by three inch channel tongue, you can use two of the Titan adaptor spacer kits, those are sold separately, available with part number T4842100. If you're using this on a three inch by four inch channel tongue, you can use one of those Titan adaptor spacer kits to get this to work.Your capacities are labeled right here. It has a 7500 pound capacity with a maximum tongue weight capacity of 750 pounds. This right here is your cap for the fluid reservoir. On the underside here, this is the connection nipple for the brake lines. And that's just connected to the fluid reservoir. But overall nice design. We're looking at a very durable, steel construction and it has protective finishing over the entire unit to keep it safe from rusting and corrosion.That's going to do it for today's look at the Swing-Away Actuator with the manual lock-out.

Unfortunately the Titan Brake Actuator shown in the video is no longer made by the manufacturer. I've linked our current selection of surge brake actuators below that you can look through.
