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.

Slow shipping!!!!


I go the package on time and was what I ordered. Fit well.


It fit perfectly and it works perfectly !


Spring on the lever broke almost immediately after installation.

If it is the latch spring that broke, Titan does have a Repair Kit for Titan Couplers and Actuators T1848700 that includes a latch spring.

  • Advice on Replacing Old Surge Brake Coupler with Non Surge Straight Box Coupler Shaft
    Thank you for including images, this was a great help to me understanding what you will need to do to equip your trailer with electric brakes. The best thing for you to do is to immobilize the surge coupler. To do this you can weld the inner part of the surge coupler to the outer sleeve, as seen in the attached photo in blue. You can also drill a 5/8 inch hole through the unit and insert a grade 5 or 8 bolt through it. If you do this you will want to make sure you choose a spot that...

  • How to Lock Out a Model 10 Actuator When Going to an Electric Over Hydraulic Setup
    I spoke to my contact at Titan and he informed me that there really isn't a simple way to lock out the sliding portion of the Model 10 actuators. You would have to either weld the two portions of the actuator together or drill holes through them and bolt the pieces together. If the actuator is bolted to your trailer the best solution would be to go with the coupler part # T4853100 as this has the same bolt pattern and is a standard coupler. The Model 20 and 60 couplers can be easily locked...

  • Availability of Model 10 Trailer Actuator for Disc Brakes
    We have a solution, but we don't have a Titan Model 10 actuator currently that is designed for disc brakes. What you could do is swap in the disc brake actuator part # T4747100 to the # T2477600 and you'd have a Model 10 designed for disc brakes.

  • Surge Brake Actuator Needed That is Compatible with Drum Brakes and a 2-5/16" Hitch Ball
    If you are looking for a brake actuator that works with drum brakes and a 2-5/16" hitch ball then 2 of our most popular options are from Titan. We have a weld-on application with part # T1521000 as well as a bolt-on application with part # T2477600. These fit 3" wide trailer tongues and do not come with lockouts.

  • How to Determine if Replacement Coupler Inner Slide part # T1608400317 is Correct for Actuator
    Easiest way to tell will be to check out the product pictures of the # T2477600 which is a Model 10 actuator like what the part # T1608400317 is designed to fit. Most actuators are about the same dimensions as they are all designed to fit 3 inch channel so by dimension would not give you the best results.

  • Master Cylinder Replacements for Titan Actuators
    I was unable to find an order number for you so I'm not entirely sure what you have, but were you referring to the Replacement Master Cylinder Cap with Diaphragm for Titan Model 10 and 20 Brake Actuators # T4830601? I only ask because there is not a model 0100, but there is a Model 10 such as part # T2477600. A master cylinder cap will only fit the direct model it is designed for so you will need to know your actuator's model in order to get the correct cap. The Replacement Cap for...

  • Replacement for Atwood Surge Brake Actuator
    The Atwood MPD 85778 is not actually a model number for their actuator, it is a literature number - basically a manual number so I wouldn't be able to tell you what a direct replacement would be. You will need to match your actuator to either drum or disc brakes, the weight capacity, coupler size and what size tongue it bolts onto. For example, if you had disc brakes, a 3" wide channel tongue, needed a 7,000 lb capacity and had either a 1-7/8", 2" or 50-mm hitch ball a great option...

  • Can I Convert My Titan Surge Brake Actuator To Have A Reverse Lockout?
    I am not aware of any Titan Surge Brake Actuators having an available manual lockout for them. It is possible to convert some of the Titan Zinc-Plated Brake Actuator # T2477600 to an electric lockout. To do this you will need the Solenoid Valve for Titan Brake Actuators # T4748800 that will work with Titan Model 6, Model 60, Aero 7500, and newer Model 10 and Model 20 actuators. For 2000 and older Model 10 actuators, a Solenoid Adapter Fitting # T4750200 will be needed. A Solenoid...

  • Parts Needed To Replace Hydraulic Braking System On Boat Trailer
    Hydraulic systems are preferred on boat trailers because water and electricity do not mix well. The hydraulic surge brake system is self contained on the trailer and the only connection to the vehicle is the reverse lockout switch that is powered through the trailer connector. This switch keeps the surge coupler from locking the brakes on the trailer when you are backing up. I know that you told me that your boat weighs 6k, however I need your help to identify the axle so we can select...

  • Coupler Lock for Dexter DX12.5 (Model 10) Actuator with Wide Lip
    The Master Lock Trailer Coupler Lock # 377DAT you purchased can accommodate a max coupler width (including lip) of 4 inches , so for a lock that works with up to a 4-3/4 inch coupler width, I recommend the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33-40D. I pulled our Titan Model 10 actuator # T2477600 (Dexter DX12.5), and found that it measures just over 4-5/8 (4.63) inches edge to edge of the coupler lip, so the BLTL-33-40D will definitely be wide enough and work perfectly with your...
