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.

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

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

Still works as it should



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:

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



by:

It was late in the day when order this I had my doubts that it would be delivered the next day and it was install took about an hour took the longest was to bleed the brakes



by:

It was easy to install and has worked well the hole time



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 This actuator is outdated and I replaced it with a better product.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:

Great product works great on my boat trailer



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!?

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:

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:

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:

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:

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



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:

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



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:

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.

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:

Thank you guys at e trailer, great service, good prices and was a pleasure doing business. Will definitely shop here again for all my trailer needs.



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.

delivered early, sound packaging. item is as described and shown. Will definitely reorder from e-trailer. Thank You

  • Replacement Hub/Drum and Hydraulic Brake Assembly for Boat Trailer With 3,500 lb Axle and 13" Wheels
    The # 8-247-50UC3-EZ and # AKHD-545-35-G-EZ-K will both fit and work with your 13" wheels. These are also compatible with the # 40716-15 from your previous question. For the most part it comes down to cost between the two hub/drum assemblies. However, since this will be going in the water on your boat trailer I would stick with the Dexter which has the 500-hour salt spray rating. The Hydraulic Brake Kit # AKFBBRK-35-D will work with your 13" wheels but I would stick with the Demco. The...

  • Can 7k Titan Disc Brake Actuator be Used with 6k Trailer Disc Brakes
    Yes, if you have 6,000 lb disc brake assemblies the 7k rated Titan surge brake actuator part # T43397007K will activate them just fine.

  • Will Titan Brake Actuator part # T43397007K Replace a Tie Down 70E Actuator
    Yes, the Titan brake actuator part # T4339720 that you referenced will easily replace the Tie Down actuator you have now. The fitting size is the same. I attached a review video for this actuator for you to check out as well.

  • Repair Kit Recommendation for a Titan Multi-Fit Trailer Coupler Actuator

  • Recommended Surge Brake Actuator To Replace Older Atwood Actuator
    I have a few options depending on if your Atwood actuator is for disc brakes or drum brakes. For drum brakes I recommend the Titan Brake Actuator with Manual Lockout - Bolt On - Drum - 2" Ball - 7,500 lbs # T63FR which is the only actuator we offer for a 2" ball that has the manual lockout you were wanting. This actuator bolts on to 3" wide channel tongues and has a 750lb tongue weight rating and 7500lb trailer weight rating. If your trailer has disc brakes I recommend the Dexter DX7.5...

  • Recommended Surge Brake Actuator with Manual and Electric Lockout for Drum Brakes
    It sounds like you are looking for a surge brake actuator with both a manual and electric lockout and if that is the case I recommend the Brake Actuator with Manual Lockout part # T63FR. That said, you will need to add the Solenoid Valve for Titan Brake Actuators part # T4748800 as well. The Titan Zinc-Plated Brake Actuator part # T43397007K cannot be manually locked out per the owner's manual.

  • 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.

  • 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...

  • Parts Needed To Convert Titan Model 60 Drum Brake Actuator To Work On Disc Brakes
    To convert your Titan Zinc-Plated Brake Actuator - Drum # T43397007K to Disc # T47457007K you will need to change out the Master Cylinder Assembly # T4820000. If you do not already have a Reverse Lockout Solenoid # T4748800 you will want to add that as well since there are no free backing disc trailer brakes. A Solenoid Shield # T4835800183 will protect the solenoid if you do not have one. Using a disc brake kit like the Kodiak # K2R35S will reduce rusting as the rotors and calipers...

  • Recommended Surge Brake Actuator To Replace Discontinued Fulton A60
    You are correct that the Fulton A60 surge brake actuator is a discontinued part, and that you will need to replace the entire unit. I recommend the Titan Zinc-Plated Brake Actuator # T43397007K which will work with the 3" wide tongue on your trailer, and will allow you to use a 1-7/8", 2", or 50mm hitch ball. This actuator is for drum brakes and for trailers weighing up to 7000lbs. If you do not have free backing brakes and need a reverse lockout solenoid you can use # T4748800. I included...

It is by far the best option to replace your old Titan Brake actuator. This actuator is a direct replacement for Titan T4339700 and 43397007K actuators.

  • Recommended Replacement For A Fulton A-60 Disc Brake Actuator
    Hey Jacob, I have a replacement for you that could work but we unfortunately don't have an actuator that has a built in swing-away adapter. If you go with the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX56FR you can weld on a fold-away coupler hinge, like # FHDPW330300 and attach it to your trailer tongue. This comes with an electric lockout included. It looks like you have a 7-way already on the trailer so you should just have to run one of the solenoid wires to the reverse...

  • Recommended Brake Actuator With Lock Out for 7000 LBS. Boat Trailer
    The standard tongue weight on a trailer is approximately 10-15 percent of the GTW. On a boat trailer it generally stays at 10 percent because most of the weight of a boat is towards the back end of the trailer, reducing the need for more tongue weight. This is why all of our couplers have a tongue weight of 10 percent of the GTW. If you'd like to be more definite in your tongue weight, you can always use a scale like the Sherline Trailer Tongue Weight Scale # e99044. The Titan Zinc-Plated...

  • Replacement Actuator for EZ Loader Tandem Axle Trailer With Disc Brakes
    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.

  • Solution for Replacement Cylinder for Discontinued Atwood 82543 Brake Actuator
    The Atwood TA82543 on your 1995 boat trailer has been discontinued. This means that replacement parts like the master cylinder are no longer available. The only solution is to replace the brake actuator with one like the # T43397007K you were looking at. This is a good replacement option especially if you need the multi-fit for different balls. This brake actuator does not have a lockout feature so if you need one you will have to add the # T4748800. You will also need to add a 5-way...

  • How to Pump Master Cylinder on Surge Coupler to Allow Bleeding Hydraulic Drum Trailer Brakes
    A surge coupler for actuating hydraulic drum brakes, such as Titan # T43397007K, can be pumped for purposes of bleeding the brake lines by using a 2 x 4 or similar piece of lumber to compress the coupler. The linked photo shows the general arrangement for doing this, which includes using the trailer safety chains for leverage. The complete instructions for Titan coupler # T43397007K are linked and these include a detailed procedure for bleeding the system using this wood-with-chains method.

  • Parts Needed For Installing Trailer Brakes On a Yacht Club Single 3,500LB Axle Pontoon Boat Trailer
    The best option would be to go with Disc Brakes # DE66YR. These are the best option as they repel water better than other trailer brakes and will offer superior braking. This will require the Zinc-Plated Brake Actuator # T47457107K and Brake Line Kit # HS496-251. The brake actuator uses a electric lockout so you will need a 5-way for your tow vehicle. If you have a 7-way then you will need an Adapter # A75TB or a Kit # C57187 can be used to change a 4-way to a 5-way. You could also go...

    The Titan Brake Actuator, # T43397007K, that you referenced does not include a lockout system for backing your trailer. If you have a surge brake actuator that works well but doesn't have an electric lockout solenoid, # T4748800, can be added to allow you to back the trailer the same as adding it would work with the new actuator. Along with the solenoid you will need a shield, # T4835800183, to protect the solenoid from damage, and you will need to upgrade the 4-Way connector on your...

  • Recommended Surge Brake Actuator For Drum Brakes on Tandem Axle 6K Boat Trailer
    It sounds like you are looking for a new surge brake actuator for drum brakes. If that is the case then I recommend the Brake Actuator part # T43397007K which is one of our best sellers. It has a zinc plated finish for maximum corrosion resistance, comes with a one year warranty, and is made here in the USA. In order to add a lockout you can use the Solenoid Valve for Titan Brake Actuators part # T4748800 along with the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter part # 20036.

  • Surge Brake Actuator Recommendation to Replace Fulton A60 on Trailer
    My contact at Fulton confirmed that the A60 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 work well to get your trailer back on the road again. If you want the reverse lockout solenoid as well use # T4748800.

  • Replacement For Discontinued Atwood Drum Brake Actuator For 2 Inch Hitch Ball
    Thanks for all that detailed info, and Atwood is out of business which is why you can't find the exact replacement. We do have an option for you, that will bolt on, with the caveat being you will likely have to use shims. The reason for that is the only option to replace it is a bolt-on coupler meant for 3" wide channel tongues, so it won't be quite 3-1/2" wide. So what I recommend is one from Titan, which does have mounting holes 3" apart on center like yours, but you will also need to...
