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.

by:

Original brake actuator was welded to the trailer tongue. I had to cut it back and weld a new piece of 3x3 tube steel and extend it out enough to install the new actuator. It lengthened the trailer by about a foot but worked out pretty well. The new one works great.



by:

Master cylinder works great no issues



by:

Works as it should. If I had it to do over I would go with electric over hydraulic



by:

This an almost perfect replacement for the original. I had to reroute the brake fluid line to met trailer line. Just got back from the lake a trip that had lots of mountains and we were impressed with how smoothly it worked.



by:

I have been looking to replacement for my Ezloader trailer. It was originally a TDE hitch but they don't exist. I had mistakenly measured my frame as 3 inch, but it was 3 1/4" inside. To make this work I did some sawing, welding, drilling and painting but it works better than original.



by:

Anna was great at helping me confirm what I needed to order. I installed the Kodiak 10” disc brake kit, new lines and Dexter actuator with no trouble. I got rid of my rusty drum brakes that were a hassle to clean and maintain in salt water. Shipping was fast and my order was complete. I’d definitely recommend etrailer.com to friends!!

YOU TOLD ME IT WOULD REPLACE A TIE DOWN TYPE TRAILER HITCH. IT DOES NOT.

This coupler would be a great replacement as long as your Tie Down fit on a 3 inch wide tongue with bolt holes that are 3 inches center to center. I will have our Customer Service team reach out to you.



by:

solid actuator for a fair price. The auto latch feature is a nice feature.



by:

Very happy and it performs as expected. Using it with new disc braking system.
Getting used to putting the pin in before going in reverse, of course it can also be wired electronically, but haven't looked into that quite yet...



by:

I dove into this job of replacing my entire rusted out disc brake system on my double axle boat trailer having never done it before. Between the variety of part choices and accurate descriptions coupled with excellent phone service and on site videos, I was able to rebuild my trailer brakes system and suspension in total. I compared prices with the trailer manufacturer and found that etrailer either beat the price or matched it but I chose to give my business to etrailer because of the service! I do recommend this company and will use etrailer.com again anytime!



by:

I installed this as part of a disk brake retrofit to a tandem axle boat trailer that didn’t come with brakes. It was an easy swap from my factory coupler and connected fine to the flexible brake line kit. How to bleed the brakes wasn’t obvious from the instructions and YouTube videos are mostly out of date, but all it took was a long handled flat screwdriver to action the pump and apply pressure. The drop and go system is easy to use. I wish this model had a manual reverse solenoid lockout but the electric lockout has been working fine.



by:

The hitch is great. Disc brakes vs the drums I had before make noticeably more stopping power. My one regret is that while there is a backing lockout of the surge brake via a solenoid valve, for high mountain trailering, the surge brake stays applied when you’re descending in low gear. I smoked my brakes coming down from 5,500 ft last week, expelling a decent amount of high temp red bearing grease. I guess if steep mountain roads are the norm, maybe an electric brake overhaul would have been better.



by:

I changed the brakes on my 1995 boat trailer from drum to disc. I was able to figure out what to order on the etrailer web site. The whole project was relatively easy. I just had to remove the old parts and bolt on the new ones. The new trailer hitch actuator is much easier to used than my old one.



by:

The unit is easy to install and is up and running in minutes.



by:

Actuator is quality product. I was replacing a Tie Down 70E actuator that was 10 years old ( master cylinder and backup solenoid failed due to rust sediment buildup ?)
Be aware that the actuator does not come with mounting hardware so save yours from old unit
, also does not come with instructions-download from web.
The only noticeable difference between the newer and the old unit was the backup sensitivity.
The old unit needed the solenoid energized with just the trailer -the new unit didn’t need the solenoid energized with trailer and boat unless you were going up an incline(even with adjustment of the bolts joining the two pieces)
Overall very satisfied-as a side note both Tie Down and Titan were bought by Dexter Axle



by:

I have been ordering from etrailer.com for years and have not been disappointed. Their prices are great, they communicate the order status very well, and ship the products quickly.
I have been having ongoing issues with my trailer brake pressure not relieving, thus applying the brakes continuously. This order was for a new actuator which I believe will correct the problem. I just installed the actuator and it fit as expected.



by:

Super fast shipping & part was easy to install!



by:

Great selection of products with detailed product descriptions and very fast delivery. The information on the site was very helpful in identifying the replacement brake actuator that I needed for my 17 year old trailer. Installed in 20 minutes!



by:

Works great! I wish I would have talked to a representative first. Bolt pattern didn’t match up with the old actuator, so I had to drill new holes. With my neighbors help got ur done in a couple hours. My fault. Thanks to etrailer for quick delivery as I needed to pull my boat out of the slip I was renting.



by:

Great product. I do wish is had a way to put a lock on it while attached to the tow vehicle.



by:

Excellent product with good installation instructions



by:

BEST CUSTOMER SERVICE AND SHIPPING i HAVE EVER DELT WITH! EVERYONE THERE IS FANTASTIC!!! PARTS ARE GREAT TOO, NEVER HAD A PROBLEM WITH ANY!!! A+++++++++++++++



by:

Actuator works great. Very smooth stop. Well built.



by:

Amy was a great help got me what I needed right away and was shipped and received quickly thanks so much



by:

Your service was excellent and your price was very good.

  • Can Surge Coupler Be Used on Boat Trailer With Electric Brakes
    From what you describe, it sounds like your trailer originally had hydraulic brakes that have been replaced with electric brakes. At this point, your hydraulic coupler which is also known as a surge coupler is strictly being used as a way to attach the trailer to the trailer ball. This arrangement works just fine as long as a cross bolt has been installed to prevent the coupler from being compressed. You won't need to use the mechanical breakaway, as it'll be inoperable anyway.

  • Surge Brake Actuator Replacement Recommendation for Atwood Surge Coupler
    The Atwood surge brake actuators are the ones we get the most feedback on with issues. We have the Dexter actuator part # 099-175-20 which will work great as a replacement. This actuator is designed for disc brakes like you need, has an electric reverse lockout and can fit all ball sizes as well. Titan actuators are very reliable as well.

  • Disc Brake Kit for a Trailer with 13 Inch Wheels
    The issue is that the rotors in kit # T4843300 for single axle trailers have trouble with some 13 inch wheels but not all. So what I recommend is using Kodiak disc brakes # K2HR35D (2 would be needed for a tandem axle set up). The Kodiak rotors will work with 13 inch wheels. Then you would just need the coupler, # 099-175-20, and the brake line kit, # 20TA-BLKIT. The rotors above will also need bearings and seals. For a kit for one axle use # BK2-100.

  • Brake Kit and Actuator Needed for a Tandem Axle Boat Trailer
    There are a few things we will need to know before selecting the correct brake kit and actuator for your tandem axle boat trailer. We will first need to know what type of brakes you are choosing and the gross trailer weight of your trailer before selecting an actuator. The first item to check when choosing brakes is to make sure there is a brake mounting flange attached to the axle. If it does not have a brake mounting flange, you would first need to have one welded to the axles by a...

  • Replacement For 6k - 8k Atwood Disc Brake Actuator
    Atwood is no longer in business, and the part number you asked about has unfortunately been discontinued, so it is no longer available. While I know it's not the answer you were looking for, the best option is a replacement for your Atwood actuator for disc brakes, and you can choose from the hitch ball size you need to couple to as well as the weight rating. Based on my research it looks like that master cylinder was for 6k to 8k rated actuators, so you can choose from any of the following...

    I would be happy to help, but unfortunately we do not have a breakdown of the correct replacement parts for your 2005 Load Rite 20360096RTB. Instead the first thing your will need to do is remove one of your current hubs and look for the bearing number stamped in the face of the inner and outer bearing as shown in the included picture of the # L44649. If your bearings are worn to the point that you cannot read the bearing numbers you will need to use digital calipers # PTW80157 to precisely...

  • Disc Brakes for 2004 EZ Loader 3500 Pounds Trailer
    A disc brake kit that will fit your trailer is the Kodiak Disc Brake Kit # K2HR35D. You will need two Bearing Kits # BK2-100 which includes both the inner and outer bearings as well as the seal. I have included the installation video for you as well. For a brake actuator, the Dexter Brake Actuator for Disc Brakes # 099-175-20 is a great fit. Disc brakes need a different actuator than drums because they require more pressure through the brake lines. Also, if you have a steel brake line...

  • Can the Latch Mechanism Be Adjusted on the Dexter DX7.5 Drop-N-Go Brake Actuator
    I do have an option for you but there are no adjustments that can be made to the latch mechanism on the Dexter DX7.5 Drop-N-Go Brake Actuator part # 099-175-20. There are also no replacements parts for the latch so if the one you have is loose you'll need to replace the entire coupler so you can be sure the trailer is in safe, working order.

  • Conversion for Drum Trailer Brakes to Kodiak Disc Brakes on a 1989 Calkins Boat Trailer
    Yes, it should be possible to upgrade your 1989 Calkins boat trailer with 6 bolt 15 inch wheel over to disc brakes from drum brakes. The first thing you will need to do is determine the bolt pattern of the wheel, see video on how to correctly measure, and then you need to determine the inner and outer bearing part numbers, and the seal part number to select the right disc brake hub and rotor combination. Once you have the bearings for your spindle and the wheel bolt pattern figured out,...

  • Replacement for Atwood Surge Brake Actuator
    The Atwood MPD 85778 is not actually a model number for their actuator, it is a literature number - basically a manual number so I wouldn't be able to tell you what a direct replacement would be. You will need to match your actuator to either drum or disc brakes, the weight capacity, coupler size and what size tongue it bolts onto. For example, if you had disc brakes, a 3" wide channel tongue, needed a 7,000 lb capacity and had either a 1-7/8", 2" or 50-mm hitch ball a great option...

  • Trailer Brakes Stayed Locked Up unless Trailer is Disconnected
    It sounds like you have electric trailer brakes and there is a short circuit that is causing the magnets to stay energized. When you disconnect the trailer from the tow vehicle no electricity is getting back to the magnets so the brakes release. The most common cause of this situation is a dirty or corroded trailer connector. You will want to check the vehicle and trailer side connectors and make sure they are clean and corrosion free inside and out. If the issue continues to happen then...

  • New Hydraulic Brakes, Actuator & Measuring for Replacement 10 Inch Hub and Drum on Boat Trailer
    While we can get you the correct hydraulic brakes as well as an actuator, the measurements you gave for your bearings only coincide with one idler hub. The issue with bearings is that the measurements do need to be very exact, so I strongly recommend using a digital caliper like # PTW80157 and measuring your spindle where the bearings ride to get the exact measurement. Since you mentioned a 10 inch brake drum, and you got the (fantastic looking) Aluminum Viking Series Valhalla Trailer...

I recommend setting the multifit coupler for the largest hitch ball setting prior to adding the lock so it will not be removable when loosening the ball connection.

    I spoke with my contact at Fulton and they told me that the A50 coupler was for a surge brake 5,000 lb system and is no longer available. They said the parts for that are no longer available either. The coupler you will need depends on the kind of brakes you have on your trailer, either disc or drum. If you install a disc brake coupler on a trailer with drum brakes, you run the risk of having the brakes locking up. If you have disc brakes I recommend part # 099-175-20. This coupler...

These are designed for 13 inch wheels and the silver cad finish provides superior corrosion resistance for marine applications. Your wheels will need to have a 5 on 4-1/2 bolt pattern.

This is the upgraded replacement for the Titan Leverlock. Dexter bought Titan and this is the new style I think you'll really like.

  • What Voltage is Needed for the Electric Reverse Lockout Solenoid on a Dexter Actuator
    The reverse lockout solenoid on the Titan actuator # 099-175-20 is rated for 12 volts. Nine volts might do the trick but 12 volts is ideal. If you cannot get 12 volts at the reverse lights or 7-Way trailer connector then you may be able to use a fuse tap at the reverse light circuit fuse under the hood. There will be some slight movement but if the unit is banging around a lot then it could indicate worn parts.

  • Should Disc Trailer Brakes be Added to Front or Rear Axle on a Boat Trailer
    You can install disc brakes on just one axle. Install them on the rear axle which will prevent the back of the trailer from raising up if braking hard. I have included a link to the disk brake kits we have. To make sure one of these kits will fit, or to piece together a kit that will fit, I would need to know the inner and outer bearing numbers. I have included a link to a help article on adding disc brakes to a trailer that should also be helpful.

I am assuming you have drum brakes since you got the Dexter DX7.5L A-60 Brake Actuator - Bolt On - Drum - 2" Ball - Zinc - 7,500 lbs # DX27FR. You will not be able to use # 099-175-20 if this is the case, but I do have a solution.
