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.

Surge-type actuator is zinc plated for increased corrosion resistance and comes with integrated, heavy-duty coupler. Unique roller design helps reduce resistance. For use with drum brakes.


I regret buying this brake actuator for my boat trailer. This is the exact same actuator that was on the trailer when I got it, but the original was 25 years old and neglected. I decided to buy a new actuator, same as original and also replace the brake lines, baking plate and I even got the drums turned.

Well I go to fill the master cylinder up with brake fluid, open the bleeder screw and try to bleed this unit. It is the most difficult process. This is the absolute worst choice in hydraulic brake actuators for drum brakes on a boat trailer. The ONLY way you can actuate the brakes is to either use a long fulcrum (long piece of angle iron) or chock the wheels and hook it to your truck and back up. This is extremely difficult, cumbersome and just plain antiquated with today's technology. This actuator could certainly be updated with modern design/engineering and make this process much easier.


If you use a longer 2 by 4 it is much easier to get leverage to move the coupler. Another way that you can bleed the brakes more efficiently is with a Hand Vacuum Pump Brake Bleeder item # PTW87030

Purchase experience was as good as i have ever had on any product. items delivered as scheduled. Both items exactly what was ordered. Even return process was easy (my error on one item) and correct item delivered right away. Communication with vendor was excellent. Product descriptions on website accurate which made ordering a cinch. I highly recommend this vendor for any trailer parts needs.


Just installed my new 8,000LB surge tongue, shipping was fast and installation was easy, great product and works just like its suppose to, would be nice if it had a reverse lock out but because of its design it was easy to make my own lock out.


Ordered on Sunday early afternoon and received a notice that same day in late afternoon that the brake actuator had shipped. Don’t see that too often. Item was delivered in a few days and tracking the item was detailed. Brake actuator was a perfect fit in replacing an old worn out titan model 6 7500 lb with a titan 8000 lb. Easy to change out. Took maybe 20 min. Great service.


The customer service was excellent! The replacement winch strap I had originally ordered was backordered for months. ETrailor quickly notified me and offered several other options. I chose one of those options and the order was filled and shipped with only a few hours delay. The complete order arrived within a few days, well protected in a heavy duty box, and as described and expected. They are perfect replacements for my old worn out parts. Thanks!


hello: I am restoring an older boat trailer. I needed a new surge brake assembly. After looking around for days, I came across your website. It was the easiest site to use with great pictures and all the information needed to make my decision in one place. ordering was just as easy. Free delivery and great prices will bring me back


Ordered my trailer hitch come in right
time bolted on my trailer worked perfect.. Always have good luck ordering


The actuator and hitch were received very quickly and look to be exactly what I needed for repair and restoration on a 24.1 Mako. Very well packaged and at the right price.


The brake actuator fits perfectly on my Trail-rite boat trailer. Looks nice also. Will try it on the road next week.


my third Titan Model 6......seems like a new and improved version of the older ones!

Ordered it, they shipped it, all in a few days and arrived in great shape!

Thanks again,



I sometimes struggle with the coupler, could just be me. Otherwise everything else about it works good. Super easy to install


Very happy with the product so far. It looks to bolt up replacing the old hitch that was on the trailer. I have not had a chance to install T4079200 but I will update after I install...


Exactly what I needed couldn't find it anywhere else except your online store thank you so much. When you stuck on side of road with broken trailer u need it fixed fast. Thanks so much for the fast delivery


The brake actuator is fine but we were really pleased with the service. The person that took the order was knowledgeable and the order was processed fast and received in no time at all...we will do business with this company again.. Thanks


work great-just what i needed


It took me 5 minutes to put the new coupler on the old trailer. I towed it today and all is well. Thank you...


Very sturdy construction, latch works easily, and actuator woks very smoothly. Would definitely recommend!


Delivered on time, reasonable price, well packed.


It is a little hard to get connected. Requires driving forward and turning some to get the latch to shut. I feel confidant that it is not going to come loose while I am driving.


Worked great right out of the box. Easy to install and bleed. No problems so far.


Very good product!


Nice kit easy to install from opening the box to installed 15 minutes


easy to install and works great!


Product worked perfect and was delivered early! Customer very happy!


The fit was perfect! Works as specified.
