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.

I would rate it a -2 if I could. This hitch is junk. It is difficult to hitch up your trailer and I have to take it apart to unhitch. I my installer hadn’t welded it on, I would have returned it.

This coupler is trash. I would replace it if I could afford a different one.

@Roger I am happy to try to help make the coupler easier to use for you. What exactly is going on?

by: Hoby 08/11/2018

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 on, easy to bleed system.

by: Paul P 05/16/2015

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

by: Jeffrey 04/20/2023 One Year Later

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 This actuator is outdated and I replaced it with a better product.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: Dave C. 02/12/2015

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: Rich T 09/12/2019 One Year Later

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: Ken 08/14/2025

Delivered on time as promised E trailer service was excellent

by: Blake 04/30/2021

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: Bill 04/26/2022 One Year Later

The master cylinder leaks around the cap.

Jenny N.

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: Steve 07/05/2021

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: Steven 08/05/2022

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: Larry F 10/07/2016

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: JIMB 04/27/2017

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: Pam 06/16/2022

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: Todd 07/16/2018

the product was what designated via description, it was clean and sealed brake line connection.
We tested it out and it looks great.

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.

Parts arrived in excellent condition,fast shipping and I found the pricing was very reasonable. Looking forward to assembling. Will go to Etrailer first for all my needs.

by: Tony 09/05/2022

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: Larry 06/07/2016

Had to wait a month to get it, guess it was back ordered otherwise great price fast shipping works great.

Do you have a question about this Brake Actuator?

Can a Bolt-On Surge Brake Actuator Replace a Weld-On Surge Brake Actuator
Yes, you can replace a weld-on surge brake actuator with a bolt-on surge brake actuator and you can weld a bolt-on surge brake actuator to the trailer. If you are handy with a welder and have one available then I prefer this method over the other as you never have to worry about a nut backing off or drilling holes into the frame. If you can provide me with some more info on your trailer then I would be happy to recommend a surge brake actuator for you but if not I have attached our available...

Replacement Surge Brake Actuator for Discontinued 6,000 lb Atwood Coupler
The number 61101 isn't actually the part number, but I believe you are looking at the Atwood 84132. If this coupler is not opening enough to engage the ball, the first thing to check is the trigger lock. If it is not disengaged, the ball will not fit. If it is seized up, you will want to use some lubricant spray to try to see if you can get the mechanism to function. Unfortunately we don't have the replacement parts for that linkage as Atwood has discontinued them. If you need to replace...

How to Bleed Dexter Model 60 Brake Actuator
Hey Darrel, to bleed the Dexter Zinc-Plated Brake Actuator # T43397007K that you referenced you would need to use a 2x4 and the safety chains to push on the coupler of the actuator to pressurize it. See attached picture and also the attached help article on bleeding brakes as well.

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...

Parts Needed to Convert 2004 Karavan 3100 with 3700 lb Axles to Electric Over Hydraulic Disc
The 3,700 lb trailer axle makes thing a bit more interesting since the components for it are not always standard. So what I need from you is either the spindle dimensions where the bearings and seal rides or the bearing numbers that are in the hub. With that I will know for sure what parts you'd need to convert to electric over hydraulic disc.

Does The Dexter # 099-175-00 and # T43397007K Have the Same 3" Mounting Pattern?
The Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-00 does have the same mounting holes as the Dexter Zinc-Plated Brake Actuator # T43397007K. The holes are 3" on center. Yes, this actuator will be sufficient for the tandem trailer with 4 brake drums.

Should Hole In Dexter Zinc-Plated Brake Actuator Fitting Be Smaller Than Old Actuator
Hey Denver! That small hole on the # T43397007K is actually intentional. It is a built-in orifice/restrictor in the actuator, not just a standard open fitting. This helps control how quickly fluid moves through the system so the brakes apply smoothly instead of grabbing too hard. Even though it looks tiny the system is under pressure so it still delivers plenty of fluid to activate your brakes. I’d stick with the new fitting as-is and not swap in the old larger one since that could change...

Replacement Actuator for Titan Model 60 ZX7000
Hey Ushaan, welcome back! The Dexter Zinc-Plated Brake Actuator # T43397007K is the direct replacement for the Titan model 60 ZX7000. This has bolt holes 3" apart on center. The Demco Hydraulic Brake Actuator # DM72VR can certainly be used as a replacement but you're going to have to drill for an additional bolt to mount it. Let me know if you need anything else.

Replacement Coupler Recommendation for Fulton A50 Actuator
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 with lockout # T4748800. This surge brake actuator will help make your 2007 EZ Loader Trailer functional again. This has an emergency lockout cable as well.

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...

Recommended Surge Brake Actuator With Electric Lockout For Drum Brakes
We do have a surge actuator that can add an electric lockout for drum brakes. I recommend the Titan Zinc-Plated Brake Actuator, part # T43397007K. This actuator is adjustable to fit 1-7/8, 2, and 50-mm hitch balls and is a bolt-on for 3 inch wide trailer tongues. The breakaway kit is included with this actuator. For the lockout you can then use # T4748800. If you have a 7-way connector on the back of your Expedition, you will need to change the trailer connector to match. I assume you...

Replacement Brake Actuator and Braking Assemblies for a Trail-Rite Trailer
Thanks for the photo! In order to replace the surge brake actuator, I recommend taking a look at the Titan Zinc-Plated Brake Actuator part # T43397007K. This actuator is zinc plated for corrosion resistance, will work with 1-7/8"/ 2" hitch balls, and can utilize an electric lockout like # T4748800 for easy reversing. It will fit a 3" wide tongue and comes with a one year warranty. I have attached a review video for you as well. Unfortunately, we would not have the correct brake cylinder...

Complete Hydraulic Drum Brake Kit for Boat Trailer With 3,500 lb Axles
I would need some more information before setting you up. What is your axle's weight capacity? Do you have an idler hub or hub and drum? What size are your wheels?

Hub and Drum and Brakes for Trailer With 2,000 lb Axles & Bearings L44649
Thanks for that great information we have exactly what you need for your 2,000 lb axles. The number you gave of 1.063 inches in diameter where your bearings ride on the spindle corresponds to Bearing # L44649. Knowing that, we can get you the correct hub and drum, which is the Trailer Hub and Drum Assembly - 2K Axles # AKHD-545-2-2K. These hub and drums work with 7" brake assemblies and for hydraulic brakes the correct assembly is the Dexter Hydraulic Trailer Brake Kit # 23-398-399. These...

Recommended Disc Brake Kit for a Venture Salt Water Boat Trailer
John, to replace the rotors and calipers for your TDE system on your boat trailer, I recommend going with the Kodiak Disc Brake Kit # K2R35D. This kit includes the rotors, calipers, the mounting brackets and mounting bolts, will work with your current actuator, and has a dacromet coating for superior protection against salt water and fresh water. The last thing you'll need is a brake line kit # 18SI-BLKIT for a single axle, or # 18TA-BLKIT for a tandem axle. Also since you mentioned...

Replacement Coupler for Atwood Hydraulic Brake Actuating Coupler for Drum Brakes

This coupler has bolt holes that are 3 inches on center. I've attached a video to help further.

Troubleshooting Smoke Coming From Trailer Tire Area on Trailer
It sounds like you have 1 of 2 things going on. Either your tire is making contact with your trailer frame which is causing it to smoke, or you don't have enough grease on the inside of your hub so your bearings are causing all of that smoke. If it were your brake fluid you either wouldn't notice it as it would be such a small leak or your brake fluid would basically be empty. Check your tire for any signs of abnormal wear. If that looks good then you need to remove your hub and check...

Replacement Brake Actuator for 2008 Jayco Jay Series 1206
Hey Patrick! Do you have drum brakes or disc brakes? Is the actuator 3-5/8" wide or is the channel tongue on your trailer that wide? I'm guessing you have a 3" wide channel tongue which is pretty standard. Do you need a coupler for a 2" ball or 2-5/16" ball? For example, the Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-20 you were looking at is designed to fit a 2" ball, 3" tongue, and works with disc brakes. The bolt pattern probably doesn't match since it has that third bolt hole...

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.

It sounds like you have free backing braking assemblies on your trailer so a lockout at the trailer coupler is not needed.
