Actuator Dimensions

Note: Because this actuator does not include a reverse lockout, it is recommended that you equip your trailer with free-backing brakes so that you can drive in reverse without the actuator triggering your trailer's brakes.


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 hydraulic actuator is triggered as your trailer moves forward, once your tow vehicle starts to slow down. When this happens, the actuator contracts, applying force to its master cylinder. This in turn supplies the necessary hydraulic pressure to engage your trailer's brakes.


Sturdy, Corrosion-Resistant Construction

Made of sturdy steel, this hydraulic trailer brake actuator features a durable zinc coating that is designed to limit rust and corrosion. This zinc coat has a 200-hour salt spray rating. In addition, the composite master cylinder is made of corrosion-resistant, glass-reinforced nylon to further ensure durability.

Video Transcript for Demco Hydraulic Trailer Brake Actuator Installation

Today on our boat trailer, we're going to be installing the Demco hydraulic trailer brake actuator, part number 8605001. To begin an install, we'll first need to remove the old or manufacturer's actuator and coupler. To do that remove the 2 bolts that secure it to the frame of the trailer, then we'll disconnect the hydraulic line. Here's our new coupler and actuator, the back side there's a cap covering up the master cylinder and a threaded adapter. Go ahead and make sure the adapter is tight first. Then we'll thread the old line into the new master cylinder.

Once we have it tight, we'll then go ahead and install the new actuator and coupler on to the frame, note inside the frame there was a spacer that'll line up with our attachment points so that you don't crush the frame if you tighten it down. As you can see, the bolt isn't quite long enough with the new coupler, so we'll go ahead and replace the old bolt with one slightly longer using a grade A bolt. Once I have the bolt in place, I'll install a flange nut. Now I'll go ahead and repeat the same process for the rear attachment point. Now with it mounted, we'll go ahead and remove the cap on the master cylinder and install some brake fluid.

We'll go ahead and fill it up, then we're going to move back to the wheel cylinders behind the wheels and open up the bleeder valve, this will allow our system to gravity bleed. We'll need to bleed the system to get all the air out, once we have all 4 bleeders open, we'll allow it to sit and bleed out of each wheel cylinder individually then once we start to get fluid out of the wheel cylinder we can go ahead and close it and wait for the others to catch up. Now that we've bleed out our breaking system, we'll go ahead and top off the master cylinder, reinstall the master cylinder cap and we're ready to hit the road. That does it for the install of the Demco hydraulic brake actuator, part number 8605001. .

The new unit fit perfectly on my 1988 boat trailer. Installation couldn't have been easier - bolt holes lined up exactly. I watched an etrailer video demonstrating the install procedure, and by watching the video I realized that the anti-collapsing spacer tube which goes inside the trailer tongue tube was missing. I made two steel spacers and installed them inside the tongue when I installed the new brake actuator unit. I very happy I made this necessary upgrade. 501067

The unit fit exactly like the original that it replaced. Working better than the 30 year old one.

This was a replacement for the no-longer-available actuator on my '78 trailer. I had it welded on instead of bolting it on; figuring replacement parts will be available for a long time for this actuator. It has worked flawlessly, and was a great value for the price. 542218

by:

Best price on the internet for the whole assembly. I was going to rebuild my old one, but when I saw the price for a new replacement, I went with that. The quality is very good. No instructions came with it, but I found a video on the Etrailer site that showed me how to install the actuator and bleed the brake lines. Be sure to check the brass exit-fitting on the unit for tightness. Mine was very loose. The video does mention to do that. I'd suggest that Etrailer provide more packing when shipping these. Luckily there was no damage but the packing material was sparse. 177655

Demco surge brake actuator Demco brake cluster (2) Product shipped and was received within a couple of days. Finally warmed up enough to tackle this project. My tow-dolly is a 1998 so the job was a little different than the video shows. Had to wrench the bolts all the way out with a cheater ( think Loc-Tite ). Also needed a little help with a hammer to separate hub/spindle from backing plate. Went back together pretty well. New actuator went right into place. Great service. 351344

So far so good only issue was no paper work what so ever. No instructions and no warranty card, not even a packing slip. Took a bit to find installation instructions on line because I couldn’t get anyone to email me or call me back after I purchased. All installed and gave it a test run and so far so good. 512493

The trailer actuator actually arrived a day early which was excellent timing. The trailer actuator fit perfectly on the trailer and was a bit beefier than the one I had. After installation the unit worked perfectly. 575235

My brake actuator got to me pretty quick the price was great. And fairly easy install and hookup. There was no hardware to attach the line to the actuator but after $10-$15 at lowes I got all the stuff to make it work. Awesome product thabks guys. 140311

I recently ordered a master cylinder and two complete drum brake assemblies for my 1985 Mastercraft ski boat trailer. I received all of the items much quicker that I had expected. The master cylinder was pretty close to being an exact replacement for the 30+ year old assembly I had removed. The drum brake assemblies were exactly the same as the original units saving me a lot of time and money trying to find the parts I would have needed to rebuild the system. 403518

Highly recommend company! I am pleased with the direct fit of my new hitch. I took the measurements of the trailer tongue 3", bolt holes center to center 3". The hitch is rated for 6k and my pontoon boat and trailer come in at 4.4k. Nice product, heavy duty and much better than factory. Shipping was extremely fast, easy to track with etrailer email notifications. The customer email service is superior to many other companies. 541261

I ordered this surge brake unit on Tuesday and received it on Thursday as was promised, great service and great to work with. I replaced another brand with this Demco it bolted wright to my trailer tongue and just had to adjust the brake line a small amount, put brake fluid in and blead the brakes,hooked to my truck and road tested and it worked great. The price was far less then one I could buy local.if in the future I need trailer part's I will buy them here also. 298137

Thank you for contacting me about my purchase , the. Brake actutor works very well, it is the same brand as the original Actuator that lasted 15 years on my boat trailer. If I ever need more trailer parts I will consider ordering from etrailer.

It was easy to install. I like the fact that it works like a standard coupler. This makes it easy to hook up to vehicle. Costomer service was helpful when ordering. it is nice to talk to a person when ordering from etrailer. Seems to work well when pulling my boat. 576467

There is slop where coupler goes into the actuator box. When towing my 20' boat I can feel it bouncing up and down a bit after each bump. I'm considering changing out to different brand as I concerned it will round out the bolt holes and make the slop even worse. 465677


Comments

James,Thank you for your review. I have contacted demco and there will always be some movement of the coupler body in the outer case. Typically the movement measures 14 approximately. There should not be any more slack than that.

Fast shipping, Love that. This replacement hitch is perfect. It bolts up to the same holes tat are in my trailer, I was pleasantly pleased with that. The hitch is several inches longer than the original and this Ranger boat trailer. The price was unmatched, nobody came close to it, not other sites. Now to bleed the breaks and hit the water, 496241



- 8605001
by:

Very well built. If you take the two bolts off on top that hold the plate on by the breakaway lever you can then use the lever to bleed the brakes. This was a relacement for a unit with a bad master cylinder. However i had to replace my bolts holding it on because its slightly wider due to double wall construction. Very happy with purchase. 241664



- 8605001
by:

I had an older version of the hitch and it was beyond rebuilding. I ordered the new one and it arrived quickly. It was an exact replacement no issues with the install or bleeding the system, Oh and it was the best price I found on the net. any parts ordered in the future will come from etrailer.com. 397782



- 8605001
by:

I have not had a chance to use the hitch, but it was simple to install, and easy to bleed by myself. Used it to replace an at least 20 year old atwood receiver, and this one replaced it easy as pie. Since I also got the Demco free-backing brake assemblies, I'll never have to get out to back up my trailer. Again though, have not had the chance to try them out, vacation was canceled. 147381

Stripping down a 16 year old 21 ft. salt water use trailer - from end to end. The folks @ etrailer were very knowledgeable, and helpful in my decision making. From placing the order, to tracking the order, to the way the items were packed for transit. Other distributors could learn from these people; in regards to customer service, following up, both office and warehouse. Unloaded the products last night, nothing short, all quality in regards to their products, with great pricing. The installation videos are a big bonus, and something I'll be taking advantage of, during the restoration. Will follow up with picture, (before and after) when I'm done 337542

Installed today. Fit was good with 4-1/2" grade 8 bolts and flange nuts. Had blown out and used my existing brake lines as I was replacing the brakes also. Gravity bleed wasn't working for me, so I rigged up light air pressure from the compressor with the bleeders open to push the brake fluid through the lines. Then with a few times pumping the ball part of the hitch back and forth to the actuator and holding it in with a clamp as to bleed it like an auto brake, the air was bled out and the job was done. 658638

Bolted hitch on my boat trailer with Grade 8 bolts and 2 pieces of thick wall round pipe inside the frame tubing for extra support, so the frame wouldn't cave in while bolts get torqued. Brakes bled flawlessly, and all works great. Good setup. 658306

Functioned as advertised, but the glass reinforced nylon master cylinder threads leaked until the brass adapter fitting was nearly bottomed out.

I'm glad I had a pneumatic bleed kit to troubleshoot because several lines were full of sludge. Had a little trouble getting the surge actuator primed. It is best on this unit to take the 2 bolts holding the emergency lockout and then pulling in this device to prime the unit. Made it easy. 654971

  • Replacement for Atwood 82543 Surge Brake Actuator
  • The closest option we have to replace your Atwood 82543 actuator is part # 8605001, which is the item you referenced. However, this actuator doesn't have the lockout like your Atwood does. For one with a lockout use # T4339720 but it's an electric lockout. It wires into the reverse lights on your vehicle via the circuit on your trailer connector.

The review you are referring to, the customer did indeed weld the brake actuator to his tongue but this is not required for installation because it is a bolt-on actuator.

  • How To Determine If Your Trailer Has Free-Backing Brake Assemblies When Replacing a Surge Coupler
  • To find out if you have free backing brakes, there are really only two ways I can think of to test. First, if your coupler works, you can push your surge coupler to move your trailer in reverse. If the brakes apply, then you know you do not have free backing brakes. If you can move it easily, then your brakes are free backing. If your coupler is broken and thus the reason you are replacing then you will need to go to the second testing option. You will need to pull one of your hubs...

  • How Do I Know If I Have Free-Backing Brakes?
  • Your trailer must have free backing brakes if you have never used the surge brake actuating coupler reverse lockout. If you did not have free backing brakes, your brakes would most likely brake even if they didn't lock up when you back up because of the trailer weight pushing against the hitch ball. The only way to know for sure is to pull your hub/drum off the spindle and look at the hydraulic cylinder. Free-backing brakes like # AKFBBRK-7R-D will have only one pin coming out and...

  • What is the Difference Between a Manual Lockout and No Lockout Brake Actuator
  • A brake actuator with a manual lockout, like part # T4500600, will have a lockout lever on the actuator that prevents the internal spring and shock from engaging the master cylinder when backing up (see photo). A no lockout brake actuator, like part # 8605001, does not have this feature, so the trailer would either need free-backing brakes or an electric lockout solenoid like part # DM11993 to keep the brakes from locking up while in reverse.

  • Replacement Parts for Balcrank 16006 Brake Actuator
  • To replace your surge brakes there are a few things you'll need to know, the first being if you have drum or disc brakes. You can then choose the correct disc or drum brake assembly; you'll need to know your axle capacity and wheel size for either. You will also need to know your bolt flange pattern and drum size if you have drum brakes. You will then need the correct brake actuator and a brake line kit, which is going to be different if you have disc or drum brakes. I have added links...

  • Adding Manual Lockout to Surge Brake Actuator
  • The reason there are different actuators for disc brakes and drum brakes is the psi the brakes operate at. Disc brakes operate at a higher psi than drum brakes and either too much or too little pressure can cause damage to the brakes. There are units that can have manual reverse lockouts installed but not all.
