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.

Not a fan because of the screw down and up for ball attachment. Unit Itself works great.

Chuck

Very good and easy to install on my 1998 boat trailer. Not a fan of the screw down coupler but thats a minor issue....



by:

Bolted right on with no problem. Now to pull off the hubs and check the wheel cylinders



by:

I absolutely hate the twist lock on it. Received this twist lock style instead of what was pictured with a flip latch. Called to speak my piece about it and was told it was all they had. Now I'm stuck with it. I hate it!



by:

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!



by:

This is an inferior product as it has no opening to pump brake fluid for bleeding brakes like better actuators. You must use a 2X4 or other items to pump actuator. Also, better actuators have auto lock with locking pin for securing to towing ball rather than a screw down. This actuator is outdated and I replaced it with a better product.



by:

Product was as ordered. Shipped promptly. Only been used two times and works fine



by:

Great product works great on my boat trailer



by:

So far it looks like it will work. We have yet to install it.



by:

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!?

Paul P.

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



by:

Excellent value, great heavy duty product, fast and easy installation, perfect fit.
Can't ask for more!



by:

Fast delivery & looks like the right brake actuator will install later this spring boat in storage. Very good service will recommend my friends to your company. Thanks for your help David Castle

Its working great replaced my 26 year old brake actuator



by:

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.



by:

Very easy to install, I took the old unit off and had the new one installed in less than an hour. I hooked the trailer to my truck and primed the Hydraulic cylinder before I attached the brake line. No problems.



by:

Seems to be what I needed to have replaced, was easy to install. Only problem, NO instructions. I did find video suggestions online.



by:

This product perfectly replaced my tongue master cylinder on my 1992 Capri boat trailer. It bolted right up and the brake line thread was the same. It was super easy. It is a huge improvement!



by:

Perfect replacement for my existing brake. I'm using this brake coupled with the Titan actuator W/reverse lockout solenoid since there is no manual lockout and I don't have free backing brakes.



by:

I cannot say enough about etrailer!! I ordered my part at a much cheaper price than I would have paid locally, it was mailed the same day and I got it three days later!! When ordering, I spoke to Shawn who was very professional and very precise in my wishes......she made me feel like a very valuable customer!! The part arrived in perfect shape and was easy to install. I would not hesitate to order from etrailer again!! Keep up the good work!!



by:

Arrived corroded and not functioning properly. I had to disassemble and clean the rust that was on the inside of the fluid reservoir and the piston. I would have sent back but I needed it at the time. The piston was frozen. It took some time for me to figure this out.



by:

The master cylinder leaks around the ca p.

You mentioned that the master cylinder is leaking around the cap. I suggest replacing the cap and we do have it available. It is part # T4480701 on our site.



by:

DO NOT...I REPEAT DO NOT BUY THIS PIECE OF JUNK (I have stronger words but you get the idea) You get this piece of junk and ZERO info. I'm going to stop reviewing now before I go off the deep end!



by:

Just as shown online product fit perfect great to see a company that has great service and low prices. I will buy again when I need something. Brake actuator looks exactly like my old one saved a lot of time and money.



by:

The part was a perfect fit and the service was prompt and friendly. I had a question and the person on live chat was friendly and helpful. I would definitely use etrailer again



by:

good stuff, nice product, shipped fast, exact fit / this is just what I wanted I had questions called and asked and got answers / the price couldn't be beat I tried other on line and local stores / am a happy camper I would buy here again.
George O



by:

  • Recommended Replacement Actuator For Fulton A50 On 2007 EZ Loader Trailer
    My contact at Fulton confirmed that the A50 series is now obsolete and they don't make replacement parts. For a replacement, I recomemend the Titan Zinc-Plated Brake Actuator - Drum - Multi-Fit Ball - Bolt On - 7K # T43397007K. This surge brake actuator will help make your 2007 EZ Loader Trailer functional again.

  • What Causes Trailer Surge Brakes to Pop Forward or Delay Release of Brakes When Accelerating
    Sounds like a bad shock in your surge actuator. Do you know which actuator you have? If it's a Model 60 like the actuator you referenced the correct shock would be the part # T2336200.

  • How To Bleed Hydraulic Surge Brakes On Titan Model 60 Multi-Fit Brake Actuator
    To bleed the brake lines on a Titan Zinc-Plated Brake Actuator # T43397007K I recommend using the Powerbuilt Brake Bleeder # ALL648591. This has a magnet that will hold the catch container where it is easily visible. Using the 4 steps detailed in the images below you can use a 2x4 to activate the surge brake while a 2nd person is opening and closing the bleeder valve at each brake cylinder. Do start with the brake assembly furthest from the master cylinder.

  • Will Titan Zinc-Plated Brake Actuator Fit 4 Inch Tall Trailer Tongue
    You will need to measure the outside dimension of the trailer tongue you are wanting to mount the Titan Zinc-Plated Brake Actuator, part # T43397007K on to. It is designed to fit over a 3-inch wide tongue. If your tongue measures 3 inches wide then the # T43397007K will work well for you. This actuator will work with 1-7/8 inch, 2 inch or 50 mm hitch balls and has a capacity of 7,000-lbs.

  • Replacement Brake Line With Fittings For Titan Model 60 Actuator
    I took a look at your Titan Zinc-Plated Brake Actuator # T43397007K, and I do not think that's a quick disconnect line, I actually believe what you're needing is: - The Titan Hydraulic Brake Line with Fittings # T0776500. This line measures 18-25/32" long, and connects hydraulic brake actuator to trailer brakes. Both ends of this line are fitted with 3/8"-24 UNF male and female fittings. If this is too short for you let me know and I can see if we have a longer line for you.

  • Best Options for Replacing Hydraulic Drum Brake Actuator on Jayco Eagle
    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...

  • Recommended Replacement Surge Brake Actuator For An Atwood 85778
    Since the Atwood actuator line was discontinued, the Titan Zinc-Plated Brake Actuator # T43397007K has been one of the most popular replacements for it. This is rated up to 7,000 pounds and can accept both 1-7/8" and 2" balls, so it is a very good option. However, we do have an alternate that you may want to take a look at. The Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-00 will be rated a little higher at 7,500 pounds, but will only accept the 2" ball. Both of these are American...

  • Titan Model 60 Drum Brake Actuator with Electric Lockout
    The Titan model 60 drum brake actuator # T43397007K does not feature an electric lockout but does have the multi-fit type ball coupler rather than a lever lock style. You can simply add an electric lockout to the existing coupler. This will save you time and money. My contact at Titan confirmed this is a good way to go. You can use parts # T4748800 and # T4835800183.

  • Can Reverse Lock Out Solenoid be Left On Titan Model 60 If Never Needed
    If you never plan to use the reverse lock out solenoid that comes with some of the Titan Model 60 actuators you could remove it if you wanted to, but if you never wired it up you could just leave it on there and it wouldn't ever activate or cause issue. The solenoid is normally open so it wouldn't close on you at any point if never wired up. If you are purchasing a new coupler, I recommend simply getting one without the lockout solenoid like # T43397007K for example because it is one less...

  • Recommended Replacement for Tie Down Engineering Model 70 Surge Drum Brake Actuator
    I'd recommend the Titan # T43397007K 7K capacity Drum Brake hydraulic trailer coupler. The coupler doesn't include a lock out, but an electric lock out solenoid can easily be added using part # T4748800. The solenoid shield, part # T4835800183 is also highly recommended. The coupler is compatible with 3 inch wide trailer tongues, and can be used on 1-7/8, 2 inch or 50mm trailer balls. I've linked to some product description video that you might find helpful.

  • Locking Options for Brake Actuator
    You can use the Trailer Coupler Lock for Surge Brake with 3-3/8" Span, part # e98888, to lock a actuator like # T43397007K once it's attached to the hitch ball through the latching mechanism on the top of your coupler. This product has a wide width so it will clear the sides. The Master Lock 1-7/8" and 2" Trailer Coupler Lock, part # 377DAT, is an option that locks the trailer when it's not connected to the hitch ball. It attaches where the trailer hitch ball would go.

  • Replacement Master Cylinder Recommendation for Titan Model 60 # T43397007K Drum

  • How Tight to Get Latch of Multi Fit Ball Coupler on Hitch Ball
    The tightness needed for latching the Titan Zinc-Plated Brake Actuator # T43397007K to a ball successfully is "hand tight" which means you'd get it snug by hand which means the latch will be tight enough to secure to the ball but not so tight that movement is restricted.

  • Troubleshooting No Fluid In Reservoir On Titan Model 60 Actuator
    The reason your reservoir is empty on your Titan Zinc-Plated Brake Actuator # T43397007K is likely due to a leak somewhere in the brake lines, calipers, or master cylinder. You're going to want to check the undercarriage of your vehicle for leaks to see where the problem may lie. If you've already inspected your lines, brake calipers, and master cylinder and confirmed they are in good working order, then you can simply replace your master cylinder with the Replacement Master Cylinder...

  • Hard Brake Line is Too Long to Install a Titan Brake Actuator with Electric Lockout
    Since the hard line that you have is too long you need to either cut it to length or just shorten it and install the Titan Hydraulic Brake Line # T0776500. You will need to flare the hard line though so that it fits the actuator. If you would rather just replace the brake line on your trailer with flexible hose then you can use the Kodiak Kit # 18SI-BLKIT for a single axle trailer or part # 20TA-BLKIT for a tandem application. I have linked our selection of flexible hose kits for you to...

  • Trailer Coupler is Stuck on Hitch Ball and Will Not Release
    First, release the mechanism that holds the coupler onto the ball. It may be a lever or a knob that has to be turned. Some require a dual action move where you would push back or forward on the lever while lifting up on it. If you have done this and it seems to be stuck then it is most likely a binding issue. You can try moving the tow vehicle and trailer forward or backward to release the tension between the ball and coupler. Binding can occur if the trailer and tow vehicle are not on...

  • Titan Model 60 With Lockout for Drum Brakes
    Titan offers a bolt-on Model 60, # T43397007K with lockout # T4748800 for trailers with drum brakes. It works with trailers that have a 3" wide channel tongue and a 7,000 lb. weight capacity. I've attached a link to our article on trailer couplers as a courtesy. I also recommend purchasing a coupler lock like # ML389DAT to secure trailer and boat when not hitched to your vehicle.

  • Replacement Dico Model 60 Brake Actuator for Trailer Drum Brakes
    To replace your Dico Model 60 surge brake actuator for your trailer's drum brakes I recommend the Titan Zinc-Plated Leverlock Brake Actuator, part # T43397007K. This is the Model 60 Brake Actuator designed for drum brake applications and has a weight capacity of 7,000 pounds. I have attached a short video demonstration on this actuator that you can also check out.

  • 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.

  • Sizing Requirements and How to Install a Brake Actuator on a Wider Channel
    The Demco actuators and the Titan brake actuator item # T43397007K you were looking at are all industry standard to fit over a channel tongue that is up to 3" wide. I have attached a pic of the Titan actuator installed inside the channel and welded onto the sides. If this install method does not work for your trailer than I recommend having a professional welder modify your trailers channel so you can install the proper hitch actuator.

    It sounds like you have a UFP A-60 brake actuator on your EZ Loader trailer. The # T43397007K is designed for drum brakes so this would not be a suitable replacement. Instead, I recommend the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout - Bolt On - Disc - 2" Ball - Zinc - 7.5K # DX89FR. This is a direct replacement for a UFP Model A-60 actuator like the one you have now.
