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.

Awesome exactly what I needed for replacement. The price; well the trailer hitch guy in town said he could order me the same thing for $790.00 plus $100.00 shipping cost and it would take three weeks to get here. Obviously he didn't get my business and and big thanks for a great product at a great price!

I ordered the Titan Zinc-Plated Brake Actuator to replace the rusted out old one on my boat trailer. The item I ordered showed up sooner than anticipated and was exactly as represented on the website. I can't wait to install it and have the brakes on my boat trailer working again for many safe trips to the boat ramp.

I had originally ordered just the replacement master cylinder for my actuator but after taking mine apart, there were way more parts that were needed to repar it. I called the service center and they were very helpful in cancelling the master cylinder order and guiding me to this assembly. It was in my hands in 3 days and in time to get the boat in the water.

Ask the Experts about this Titan Brake Actuator

  • Best Coupler Lock For Titan Model 10 Coupler for 2-5/16 Hitch Ball
    The best trailer coupler lock for your Titan Model 10 Brake Actuator # T2478100 is the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33-40D because it locks your actuator with a stainless steel padlock that has a hardened steel shackle and busting through it would require not only a lot of time, but some significant tools. An everyday thief would have no chance of coming away with your trailer if you have this lock on your Titan actuator. For added security so you will always be able...

  • Can Titan Model 10 Actuator be Locked Out When Backing Up
    You can pretty easily add an electric lockout to the Titan Model 10 actuator part # T2478100. For that all you would need is the part # T4748800. This will then allow you back up a hill without the brakes locking up.

  • How to Bleed Brakes on Trailer Equipped with Titan Model 10 Hydraulic Brake Actuating Coupler
    Begin by removing the master cylinder cap and fill the reservoir to three quarters full with DOT-3 brake fluid. DO NOT allow brake fluid to contact painted surfaces since it will damage the finish. Wipe up any spills immediately and wash the area with water. If you choose to manually bleed the system, an assistant makes the job easier. Manually pull the actuator out to fully extended position. Loosen the four bolts on the breakaway lever. Remove the back two bolts, rotate the two breakaway...

  • Replacement Brake Actuator For A Gross Trailer Weight Of 10,000 Lbs.
    Absolutely, the brake actuator we have that most closely matches your gross trailer weight (GTW) of 10,000 lbs, is our Titan Zinc-Plated Brake Actuator part # T2478100. If you do not wish to have a 3" drop for the hitch ball, you will want part # T2477600. The Titan actuator is rated for a gross trailer weight up to 12,500 lbs and will fit over a 3" wide trailer tongue. If you are using disc brakes then you will need the Titan Zinc-Plated Brake Actuator w/ Electric Lockout part # T4750820.

  • Is a Titan Model 10 Actuator Worth Repairing or Should It Be Replaced
    It would be really difficult for me to determine the cause of the issue without being able to tear down the unit. We do have some of the replacement parts for the Titan Model 10 Actuator but they are getting harder to find everyday so rather than dump more money into the unit a replacement would be the best option. The Titan Zinc-Plated Brake Actuator part # T4750600 for disc or part # T2478100 for drum is what I recommend.

  • Understanding the Lockout Function of an Actuator and How to Add One if it's Not Included
    The reverse lockout on an actuator like the Titan Zinc-Plated Brake Actuator, part # T2478100, is a feature that prevents the actuator from activating your brakes while backing up. Without it, when you back up, the actuator compresses and applies the brakes. This can make backing up difficult especially on an incline. Luckily, this actuator can easily be equipped with lockout by using the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts, part # T4748800. It...

  • How to Modify Drum Brake Actuator Coupler for Use with Disc Brakes
    Brake fluid pressure requirements for disc and drum brakes are too different to allow use of a disc actuator on drum brakes. Disc brakes typically need 1500-psi while drums need about 1000-psi. Brake proportioning valves do exist but we do not sell them. From a safety standpoint we do not like to recommend using a device like that. We always recommend using the appropriate actuator for the type of brakes on the trailer. Some actuators can take either drum-brake-pressure master cylinders...

  • Can a Titan Model 10 Actuator for Drum Brakes be Used with Disc Brakes
    The part # T2478100 is indeed designed for use on trailers with drum brakes. The master cylinder of the actuator is designed for lower pressure drum brakes. What you can do is swap out the master cylinder of the actuator with the part # T4749501042 and it would be compatible with disc brakes.

  • Can a 12,500 Pound Brake Actuating Trailer Coupler be Used in Place of a 7,500 Pound Coupler
    If you go with a higher capacity brake actuator than what the trailer requires the braking can be very aggressive. If the trailer is supposed to have a 7,500 pound capacity actuator then that is what I recommend sticking with that or going up to an 8,000 pound model such as # DM8759411.

  • Actuator Coupler Latch Will Not Stay In Slot
    First, I recommend checking the size of the diameter of the hitch ball you are using. The Titan Zinc-Plated Brake Actuator # T2478100 is designed for use with 2-5/16 inch diameter hitch balls. If the hitch ball is too small, the coupler may be hitting the hitch ball too far down and preventing a secure connection. If you are using a 2-5/16 diameter hitch ball, it sounds like there may be something preventing the actuator from hooking fully around the hitch ball. The shoulder of the...

  • Electric Winch and Surge Actuator Recommendation for Trailer Towing 9,500 lb Boat
    When it comes to choosing a winch for a boat trailer, there are a few general rules we can use. The boat-size-to-winch capacity is generally 2 to 1. With good rollers and short winching distances, the ratio can increase to 3 to 1 and with wooden bunks and long winching distances, you will want to reduce the capacity to 1 to 1. For an electric winch that would work well for you the ComeUp winch part # CU644501 would work well. This has a 4,500 lb capacity and a 50 foot long synthetic...

  • Comparison of Two Titan Hydraulic Trailer Brake Actuators
    The two Titan brake actuators, parts # T2478100 and # T4750600, are the same actuator except the former is for drum brakes and the latter is for disc brakes. Part # T4750600 operates at a higher pressue (around 1,500 psi) which is what is required for disc brakes where part # T2478100 only operates about 1,000 psi. You want to select the appropriate actuator because the higher pressue is too much for drum brakes and the lower not enough for disc.

  • Replacing a GDC100 Surge Brake Actuator
    I was unable to find much information about the Global Direct GDC100, but that doesn't mean we don't have anything available for you. The Titan Brake Actuator # T4747220 is rated to 8,000 pounds and has electric lockout. The Titan # T4750820 is much the same, but it is rated up to 12,500 pounds if more capacity is needed. Both of these options are also rate for use with disc brakes. If you needed an actuator for drum brakes, the Titan # T4079200 will be rated to 8,000 pounds and the...
