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.

Direct Bolt on, better than welding. Surge Brake Line connected just fine. Bled Brakes. Test drive was successful. What more could you ask for. I chose the hand tightening knob over the Lever because it was more assuring to me that it was tight on the ball and the locking mechanism has never failed. I have used Titan surge actuators for 40 years. I am using this actuator on a 4,000 lbs. boat and trailer. On my way to the lake!

Bolted right onto the trailer. No instructions and the link on the web sit didn't work but what do you need for two bolts. Wouldn't have minded some guidance with bleeding the brakes but got it done anyway. Greatly improved the towing of my boat trailer! Good price. Shipping good. What else would you want!?

Well, it worked great till I sold the boat last October. Shocked about the follow-up! Wow

Excellent product. This was almost an exact replacement for the original one that was on my boat trailer. I had the boat out about once a week this summer and the actuator worked perfectly. Braking was smooth and it locks down easily on the hitch ball. I highly recommend this actuator.

    There are a number of things you'll need to know before choosing the right brake actuator for your Jayco Eagle. Atwood MPD 85778 is actually just the literature number, so I wouldn't be able to tell you what a direct replacement would be. It's important to remember you'll need to make sure your actuator's coupler matches the size of the hitch ball on your tow vehicle, with the common size being 2 inches. As for the lockout, your brakes aren't going to require them but it's a highly desired...

  • New Actuator Recommendation to Replace Atwtood Coupler on Tandem Boat Trailer
    That looks like an older Atwood coupler. Which I am not surprised it isn't working as it's the most problematic actuator that we have experience with. Most popular coupler we have that would work as a replacement would be the Titan actuator part # T43397007K as it fits the same channel width as what you have and has a 7k capacity for drum brakes. It also can fit either a 2 inch or 1-7/8 inch hitch ball.

As a general summary, you will first top of the master cylinder with appropriate fluid.

  • Master Cylinder is Not Pumping Fluid
    If your actuator, like part # T43397007K, is new and you are testing the master cylinder without it being in the fully assembled actuator then that would be your problem. If your actuator is not new then you will want to look for any clogs in the brake line. There should be fluid moving through the line even with it being disconnected from the brakes. Try cleaning the brake line and if that doesn't help let me know and I can help you to troubleshoot further.

  • Replacement Surge Brake Actuator For 1979 Rolco Boat Trailer
    It sounds like you need to replace the brake actuator on your 1979 Rolco trailer. When you say the hitch portion are you asking about a surge brake coupler on the trailer? These were used a lot on trailers from that time. I have attached a link to our product page for the surge couplers we offer. As you can see on the page, choosing the right coupler will depend on the size hitch ball you use and also the trailer tongue channel size. Also, the couplers have a weight capacity and vary by...

If parts are available, it might be feasible to replace parts as needed, but this will depend on the age of the actuator and the availability of parts.

It sounds as if one is hanging or the brake line is not letting the brake fluid to back out and release the pressure. In most cases when a single side is binding it is at that side. If it was the actuator I would think that it would effect both sides evenly. To test this apply pressure to the front of the actuator with a board and the...
