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.

  • 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...

  • 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...

  • 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...

  • 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 Coupler for Atwood Hydraulic Brake Actuating Coupler for Drum Brakes
    The Atwood brake actuating coupler number 61101 is no longer directly replaceable. Atwood has been bought out so I recommend replacing your actuator with the Titan Zinc-Plated Brake Actuator # T43397007K which can use # T4748800 as an electric lockout solenoid. 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 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...

  • 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...

  • 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...

  • 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...

  • Looking for Replacement Master Cylinder for 2007 Jayco Jay series 1007
    Hey Tom, do you happen to know what brand of surge brake system you have? I would need to know that to be sure on what you need. You can also email me back with pictures of it if you aren't sure. Hopefully it's not an Atwood as they are no longer made.

  • 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.

  • 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? I'm going to send you a link to a couple of help articles on what you'll need to add brakes and if you can get back to me with more info I'd be more than happy to help.

  • 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

  • Will Titan Brake Actuator part # T43397007K Replace a Tie Down 70E Actuator

  • Repair Kit Recommendation for a Titan Multi-Fit Trailer Coupler Actuator
    Based on what you described it sounds like you need the Latch Repair Kit # T4045400 for your Titan Zinc-Plated Brake Actuator # T43397007K as this comes with the nut and latch that you have broken.

  • 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.

  • 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...

  • What is Purpose of Metal Cable on Top of Titan Model 60 Actuator
    The metal cable on top of the Titan actuator part # T43397007K is the breakaway cable. This attaches to your tow vehicle so that in the event the trailer was to become disconnected the brakes of the trailer would apply to stop it and prevent it from running away and possibly hitting someone. You can reset the breakaway as well. I've spoken with Titan about resetting their model 60 actuator breakaway levers in the past and they have told me that you have to remove the cover and then carefully...

  • 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...

  • 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.

  • 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...
