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 Titan Brake Actuator - Surge Brake Actuator - T4079200 Review

We're going to take a look at the Titan zinc-plated, bolt-on drum brake actuator, designed for the 2-5/16 standard ball. It has an 8000 lb weight capacity. How this hydraulic actuator will synchronize your trailer brakes with your tow vehicle brakes. Uses a unique roller design that'll reduce the resistance during the telescoping of the actuator to create a nice straight line movement. It is a sturdy durable steel construction, so that will help resist bending in any jack-knife situations. The coupler rod up front here is a standard heavy duty coupler designed to fit on a 2-5/16 hitch ball. Uses the lock right here that just pull up on this and when you open this up and allow the hitch ball to go in there, and when you close it that link ring will lock right into place to hold the hitch ball in there. Now it also comes with a standard breakaway kit here, which is included, just to show you when I unhook this.

You have your cable on the end of the carabiner hook and that carabiner hook will attach to your tow vehicle and the other end you can see here is attached to this lever. If you get into a situation where the trailer would ever come detached from the tow vehicle, it'll pull on this cable which will activate the lever and that'll activate the brakes on the trailer to keep it from a runaway situation. Now this actuator has a nice zinc-plating to it, provides corrosion resistance. If you look on the bottom here you see hose here, this is a bolt-on installation to your trailer top. The application on this is for hydraulic drum brakes, as I mentioned this fits a 2-5/16 standard hitch ball. Mounting this you'd need a 3" wide channel tunnel that this will mount to.

The weight capacity on the actuator is 8000 lbs. the maximum ton weight is 800 lbs. The last thing I'll show you, on the very back here you can see here is your connection for your hydraulic brake-line. Underneath is the master cylinder. You can see the cap here that you can put fluid into your master cylinder. Now this model does not use a reverse lock-out on it, so it is recommended that you equip your trailer with free-backing brakes, so that you can drive in reverse without triggering your trailer brakes. That should do it for the review on the Titan zinc-plated, bolt-on drum brake actuator for a 2-5/16 ball and a 8000 lb weight capacity..

  • Replacement Brake Actuator for Global Direct GDC-80 Brake Actuator
    We have the perfect replacement for your Global Direct GDC-80 brake actuator. Since you mentioned "down tongue" I believe you were referring to having an actuator with drop. If you have disc brakes, the best option is the Demco Hydraulic Brake Actuator w/ Drop - Disc # DM8758811 and if you have drum brakes the best option is the Demco Hydraulic Brake Actuator w/ Drop - Drum # DM8759411.

  • Recommended Electric Lockout or Free Backing Brake Assemblies for Surge Brake Actuator
    The Titan Zinc-Plated Brake Actuator - Drum - 2-5/16" Ball - Bolt On - 8,000 lbs # T4079200 does not have a manual lock-out. Because of this, it is recommended to use an electric lockout like # T4748800 or free backing brakes so that you can back your trailer without activating the trailer brakes. You can use the Hydraulic Brake Kit - Uni-Servo - Free Backing # AKFBBRK-35-D for 10 inch assemblies or # AKFBBRK-7 for 12 inch assemblies.

  • Is Mounting Hole Spacing The Same On T4079200 And T4853100 Trailer Couplers
    The mounting hole pattern is different on the # T4853100 coupler versus the pattern on the # T4079200 coupler. As you can see in the attached photos the bolt pattern is closer together on the side of the # T4079200 coupler than on the # T4853100. You may wind up with some of the mounting holes in the same place but you will need to drill new holes for some if not all of the holes.

  • Is 8,000 Pound Titan Brake Actuator Sufficient for Trailer with 7,900 Pound GVWR
    The Titan Zinc-Plated Brake Actuator # T4079200 referenced in your question has a weight capacity of 8,000 pounds, so it is rated appropriately and will work well for your trailer that features a GVWR of 7,900 pounds. Also keep in mind that the GVWR refers to the most the trailer can possibly weigh when it's fully loaded. It is unlikely that you will actually load the trailer up to this limit. I have attached a short video demonstration on this actuator that you can also check out.

  • Is the Titan Zinc-Plated Brake Actuator T4079200 Suitable for Boat Trailers
    Yes, the Titan Zinc-Plated Brake Actuator part # T4079200 can be used on a boat trailer. In fact, these actuators are actually designed specifically for boat trailers which is why they have a zinc plating so you don't have to worry about about rust/corrosion that is associated with launching a trailer in water frequently. In regards to being submerged, I don't see any issue with this but you don't want the actuator submerged for an extended period of time. If you are just referring to submerging...

  • Can the Check Valve on a Titan Drum Brake Actuator be Removed for Use with Disc Brakes
    Technically, the check valve on the drum actuator, # T4079200, can be removed. However, it is not recommended to do so because you could end up damaging the master cylinder. It would be best to go with the appropriate actuator, # T4747200. You could also replace the master cylinder in the drum brake actuator using the disc brake master cylinder # T1777405.

  • How Long of Frame Channel is Needed to Install Titan Model 6 Actuator
    The mounting flange length of the Titan Model 6 actuators is 9-1/2 inches and the additional length the master cylinder adds to that is 6 inches so you'd want to have around 16 inches of frame channel to install a Titan Model 6 actuator like the part # T4079200 that you referenced.

  • How to Reset Breakaway Lever on Titan Model 6 Zinc-Plated Brake Actuator T4079200
    On a Titan model 6 actuator like # T4079200 the breakaway reset procedures is as follows: When the break-away lever is engaged, it is in the vertical position. It must be reset before the trailer is moved. First, carefully loosen the pressure line fitting to the master cylinder to relieve hydraulic pressure. Then remove the four bolts that secure the master cylinder assembly to the outer case. The flat front tab of the ā€œUā€ shaped break-away spring can then be placed in the top...

  • Drum to Disc Brake Conversion For Actuator
    The Titan Trailer Coupler, part # T4079200, is for use with hydraulic drum brakes, and does not have the reverse lockout feature, or the solenoid installed. If you have changed the system from drum to disc, you need to be aware that the disc brake system has a higher pressure requirement. The actuator should be compatible with a disc brake system. Disc brake systems require 1500 psi, where drum brake systems require 1000 psi. I have attached an FAQ article explaining the parts needed to...

  • Coupler Lock Recommendation for Use on a Titan 2-5/16 inch Coupler part # T4079200
    For your Titan Zinc-Plated Brake Actuator - Drum - 2-5/16 inch Ball - Bolt On - 8,000 lbs, part # T4079200, I would recommend you use a Fastway Universal Trailer Coupler Lock for 1-7/8 inch, 2 inch and 2-5/16 inch Couplers, part # DT25013KA. This coupler lock will fit virtually any coupler and should deter thieves from stealing your trailer. Before you order, I would recommend you measure the width of the lip on your # T4079200. If that measurement is less than 4-1/2 inches, you will...

  • Are Titan Disc Brake Actuators Compatible with Demco Brakes and Brake Lines
    Yes, the Titan actuators like the # T4339720 are perfectly compatible with Demco and other brands of brake assemblies and brake lines. Thankfully all of the setups are designed for the same pressure ratings so they all easily interchange with each other.

  • 8k Disc Brake Surge Actuator Recommendation
    It sounds like you have a # T4079200 and are looking to convert it so that it will be compatible with disc brakes. If you were using a single axle trailer you could simply ram a screw driver through the back of the check valve in the master cylinder so that the actuator would have higher pressure like what disc brakes require, but since you have a tandem axle trailer this setup would not give you enough fluid displacement to activate your brake assemblies. You will have to upgrade to...

  • Why Are Some Trailer Couplers Rated Near 8,000 lbs Available for 2 inch and 2-5/16 inch Hitch Balls
    Typically the larger hitch balls are used in the higher capacity applications, but there is a bit of overlap between the capacities of the 2 inch and 2-5/16 inch hitch balls which is right in the weight capacity range of the two actuators you mentioned. Around 8,000 lbs is where both sizes of hitch balls mentioned are easily within capacity. Above that is when you get into the larger hitch ball size-only territory.

    Going from an actuator such as the Demco Hydraulic Trailer Brake Actuator - Drum Brakes - Zinc Plated - 2" Ball - 6,000 lbs # 8605001 to a larger one, the Titan Zinc-Plated Brake Actuator - Drum - 2-5/16" Ball - Bolt On - 8,000 lbs # T4079200 will slightly affect the braking. It will be a smidgen more rigid due to the added strength of the larger capacity actuator, but this is something that will be very minimal and won't affect the way your trailer rides.

  • Availability of Demco 6K Drum Brake Actuating Trailer Coupler Compatible with 2-5/16 Trailer Ball
    Demco doesn't offer a hydraulic actuating coupler like the # 8605001 that's compatible with a 2 inch trailer ball. The coupler has a 6K capacity, which works fine with a 2 inch ball, so you could just replace the existing 2-5/16 inch ball with a 2 inch ball . For a ball with a 1 inch diameter shank and a 7500 lb capacity, use # 63845. For a 1-1/4 inch diameter shank and a 10,000 capacity use part # A-90.
