After inspecting the brakes on my Demco Kar Kaddy, The brake shoes had some deep cracks in the shoe lining. I started researching the best option for replacement and ETrailer had exactly what I needed. The parts showed up within a week without incident. I could of just replaced the shoes but since I purchased this trailer used I wanted to make sure everything was top notch. I purchased the complete brake set, which comes with new wheel cylinders, shoes springs and all hardware. The job went smooth, remove the wheel and tire, remove the brake drum, I took the brake drums into a local shop and had them turned, remove the brake line, remove the four bolts that hold the hub and backing plate to the axle.The bolts had loctite on them so I took a tap and cleaned up the threads. I installed the new backing plate, put some new blue thread lock to the bolts and tightened to specifications. I adjusted the brakes to the freshly turned drums, bled the brakes reinstalled the tires and wheels and I was back in business.

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.

Good quality parts. Installed and tested and they don't make any noise and seem to be working fine. Be sure to measure your axle flange and don't "assume" like I did. No big thing, I just had to use my old backing plates.

Review from a similar Demco Galv SelfAdjust Single Servo 10 Inch in Accessories and Parts


I bought an old boat trailer "70 vintage" that had surge brakes. unfortunaly the wheel cylinders were bad and needed replaced. after several atemps I could not locate the proper cylinders or rebuild kits. I came across Etrailer's brake back plate kits and was amazed at the low price so I desided to try them. They bolted right up and fit purfectly on a 40+ year old axel and are working as they should. I upgraded the trailer to the self adjusting brake kit and is very pleased with the outcome.

Received this products in record time, a week earlier than expected. In fact, haven't even opened the box yet as it is raining in California. Both issues, delivery and rain are most unexpected.

    I do have a solution for you but the answer to your question is no, the Demco Hydraulic Drum 3,500 lbs - 10" Brake Assembly # DMSB24429M is just the brake assembly without the drum. Keep in mind that when selecting a brake assembly and hubs that you make sure they will have the same weight capacity that your axle has. You will want to make sure that whichever brake assembly you choose that you get the Right Hand side as well, in this case it would be the Hydraulic Drum Brake part # DMSB24428M. I...

  • Replacement Brake Assembly Recommendation for 1997 MasterCraft 20 ft Boat
    Since your trailer has 10 inch by 2-1/4 inch brake assemblies currently all of the assemblies you mentioned are going to work. I would go with the sefl-adjusting part numbers # DMSB24428M and # DMSB24429M though since you mentioned you were interested in that option. The matching Titan assemblies are part # T4423500 for the left hand side and part # T4423400 for the right hand side. Based on the seal dimensions you listed the part # 168233 is the correct replacement. We don't...

  • Correct Hydraulic Drum Brakes For Demco Kar Kaddy Tow Dolly
    The Demco Kar Kaddy tow dolly does require these specific brakes, and there aren't other kits that will work, it does need the following: - Left Hand: Demco Hydraulic Drum Brake - Single Servo # DMSB24429M - Right Hand: Demco Hydraulic Drum Brake - Single Servo # DMSB24428M The reason for that is these brakes mount to a specific bolt pattern of 4 on 3.96" which is different than standard hydraulic brake kits; essentially, they are designed specifically for use with the Demco Kar...

  • Need Hydraulic Trailer Brake Kit for 1999 Demco Kar Kaddy Model KK360
    The Hydraulic Trailer Brake Kit, # AKUBRK-35 that you linked to is for a 10" diameter x 2-1/4" wide and for 4 bolt flange.

However, I will point out that we have the recommended replacement brake assemblies for the Demco Kar Kaddy in # DMSB24429M for the left side and # DMSB24428M for the right.

  • Trailer Brake Recommendation for LoadRite Boat Trailer with 10 x 2-1/4 Inch Wheels
    There are many possible reasons why your brake could have failed. It is hard to specify why yours may have failed. I recommend checking the reverse lock-out on your actuator to make sure it is working properly. Backing up with your trailer connected if your reverse lock-out isn't functioning could be why your brakes failed. If the lock-out isn't working, you could use the Demco Hydraulic Drum Brake Assembly - Free Backing # 40716, # 40715. These brakes would allow you to back up with...
