Video Transcript for Review of Demco Trailer Brakes - DMSB24429M

Today we're going to take a look at the Demco 10" galvanized left hand self adjusting hydraulic drum brake assembly for the Demco Kar Kaddy Tow Dolly. Now this is a marine-grade hydraulic drum brake assembly. It's used on Demco Kar Kaddy Tow Dollies with drum brakes. It is designed for use with surge-type trailer brake actuators and it's a sturdy corrosion-resistant steel construction. The backing plate is a galvanized finish backing plate. Does use the stainless steel spring hardware and a zinc plated wheel cylinder.

It is a self adjusting brake, so it does not require periodic manual adjustment like your standard brakes. These will not over adjust.It is a single serval design. There's only one plunger here so it delivers about 15 to 20% braking in reverse. They do use the riveted brake shoes for increased durability and the mounting bolts to install this is sold separately. Now you do need to make sure and remember that this brake assembly has a brake mounting flange bolt pattern of 3-1/4" by 2-1/2" and because of that bolt pattern this will not install onto a normal trailer axle.

It is designed just for the Kar Kaddy Tow Dollies. The configuration, this is a left hand driver side and the way you can tell what side this go on, is just by the size of the shoe. If you see, the length of this shoe goes from here to here. This one's all the way here.This is the smaller one. The smaller one will always face the front.

So that'll tell you that this is for the left hand side. The dimensions on this, it is 10", which is measured here to here, diameter. And the 2-1/4" measurement will be the width of the shoe on the pad, 2-1/4". But that should do it for the review on the Demco 10" galvanized left hand self adjusting hydraulic drum brake assembly for Demco Kar Kaddy Tow Dollies.

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. 352884

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. 351345

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. 186963

Review from a similar Demco 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. 193328

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. 163056

Do you have a question about this Accessories and Part?


  • 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...

  • Does the Demco Hydraulic Drum Brake Assembly Come With the Drum?
  • 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...

  • 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...
