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.

Because this model does not include a reverse lockout, it is recommended that you equip your trailer with free-backing brakes so that you can drive in reverse without triggering your trailer's brakes.

Video Transcript for Review of Titan Brake Actuator - Surge Brake Actuator - T4238500

Hello everybody. This is Jeff at etrailer.com. Today we're gonna take a look at this Titan bolt-on adjustable channel drum break actuator with the lunette ring. Has a 12,500 pound gross towing weight capacity. Now this hydraulic actuator will activate your trailer's brakes when your tow vehicle slows or stops. Basically what happens is when you apply the brakes in your tow vehicle, deceleration occurs, and the momentum will push your trailer toward the rear of your vehicle.

And with a surge brake system like this the actuator is triggered as your trailer moves forward once your tow vehicle starts to slow down. So when this happens, this actuator, the inner portion here will contract and it applies force to the master cylinder in the back here. And this in turn supplies the necessary hydraulic pressure to engage your trailer's brakes. This one is a unique top roller design. Roller right up here at the top.

This roller reduces the resistance during the telescoping to create nice straight line movement. Also, if you notice, they do insert a grease zerk fitting on the end of the roller. So it allows you to attach a grease gun to it and pump grease in there for easy lubrication. This is an adjustable channel design. Has three different mounting positions for your coupler.

The lunette ring here is for use with pintle hitches. So you can move it up or down into three different positions gives you a vertical range of about four inches of adjustment. This is a nice sturdy, durable steel construction. Resists bending in any jackknife situations. You can see it has a nice prime finish to it to provide corrosion resistance.

Now the breakaway kit, right here if you notice this chain with the hook on the end attaches to this lever right here. This is a breakaway kit and that prevents a trailer runaway situation and it is required by law. Basically, when you hook up to your tow vehicle you will also hook this hook to your tow vehicle. So the chains hook to it, and what that does, if by chance this comes detached from your tow vehicle, it'll pull that chain, which will activate the lever. And then that lever activates the master cylinder to apply the brakes. So it'll prevent a trailer runaway situation. Now this is a bolt on installation. If you look down here at the bottom, it does mount to a straight three inch wide trailer tone. Application. This is for trailers with hydraulic drum brakes. Gross towing weight capacity is 12,500 pounds. Next one-ton weight capacity is 1,250 pounds. And one note I do wanna mention on this is because this actuator does not include a reverse lockout on the back here of the master cylinder, it is recommended that you equip the trailer with either the reverse lockout solenoid that'll screw in line here, or that you have free-backing brakes on your trailer so that you could drive in reverse without this actuator triggering your trailer's brakes. But that should do it for the review on this Titan bolt-on adjustable channel drum break actuator with the lunette ring. Has a 12,500 pound gross towing weight capacity..
