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.

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!!

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.

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+++++++++++++++

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.

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.

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.

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

Ask the Experts about this Dexter Axle Brake Actuator



  • 2005 Ranger Trail Boat Trailer Replacement Hydraulic Brake Coupler
    Was there any manufacturer info on the existing coupler? Any part numbers? Unfortunately, there isn't an existing database that allows me to look up which hydraulic coupler was originally used on your 2005 Ranger Trail boat trailer. This being said, the Dexter Axle DX7.5 Drop-N-Go actuator would work well if you have a 3 inch wide pole tongue and need a coupler compatible with a 2 inch ball. For disc brakes, use the # 099-175-20, or # 099-175-00 for drum brakes.

  • Disc Surge Brake Actuator for Eagle 25 Trailer
    Since you said the trailer has a weight of around 4,000 lbs and has disc brakes the surge actuator you'd want is the Demco part # DM8605101 which is for disc brakes and has a 6,000 lb capacity plus has a reverse lock out to allow the trailer to back up without activating the brakes.

  • Difference Between Hydraulic Brake Coupler with Lockout and Without Lockout
    What a lockout on a hydraulic brake coupler does is prevent the brakes from applying when you back the trailer. An electric lock out is tied into the reverse lamp circuit on the vehicle so that when the vehicle is shifted into reverse the solenoid in the coupler is activated which prevents the trailer brakes from applying. If your boat trailer had free-backing brakes, you won't need a lockout because after being pushed a foot or so the brake assemblies disengage. For a 7500 lb hydraulic...

  • Why Arent Surge Brake Actuators Adjustable
    I can probably track down some instructions for the Dexter part # 099-175-20 but if your main concern is adjustability I can answer that right now and say no there is no adjustability. What you get is what you get with surge brake systems, but the good news is braking is somewhat proportional as the harder the trailer presses (heavier the trailer and/or harder braking) the harder the trailer brakes will apply. So you end up with pretty smooth braking but it's just not adjustable in any...

  • Is the Dexter Drop-N-Go 099-175-20 a Good Replacement for an Atwood 61101?
    As Atwood is no longer in production, finding replacements can be a bit of a pain. That being said, the Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-20 will be a good replacement for your Atwood 61101. This will handle disc brakes and has a 7,500 pound capacity. From the pictures I could find, it looks like the # 099-175-20 may bolt right to the same bolts holes as the Atwood, but don't quote me on that as I don't have a way to confirm it..

  • Solution for Using Dexter Drop-N-Go Brake Actuator with 2-5/16 inch Hitch Ball
    Dexter does not offer a version of the Drop-N-Go brake actuator like the # 099-175-20 with a 2-5/16 inch hitch ball. It would probably be the easiest if you swapped your hitch ball size from 2-5/16 inch down to 2 inch so that you'd be able to use this coupler. I attached a link to a page that has all of the 2 inch hitch balls we carry as well. You'll want to select your shank diameter (the hole in the ball mount the ball fits through) and you'll see all options that fit.

  • Replacing Titan Aero 6000 with Dexter Surge Actuator 099-175-20
    The Titan Aero 6000 does use a slightly different bolt pattern as the Dexter Coupler part # 099-175-20 so while it can work as a replacement you'd have to drill new holes or have the new coupler welded on. The brake line fittings are the same though so it would easily connect in that regard without requiring any adapters or fittings.

  • Dexter Drop-N-Go Brake Actuator Brake Line Coupler Size

We have several brake line kits available for single axle, and tandem axle applications. If you would like some help selecting a kit or would like to know what all parts you would need for a more custom setup, please let me know the number of axle as well as the distance from coupler to front axle on your trailer.

  • 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.

  • 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.

  • Recommended Trailer Coupler With Breakaway Kit Replacement
    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...

  • Replacement Solution for Atwood 82542 Actuator on Boat Trailer
    Atwood stopped making actuators a while back which is why you aren't able to find a replacement or any replacement parts. So for a solution to replace what you have the Dexter DX7.5 part # 099-175-00 would be a great solution if you have drum brakes or the part # 099-175-20 for disc brakes. I really like how easy the coupler of these actuators work as basically you can just drop them onto the ball and they latch themselves.
