Video Transcript for Review of Demco Brake Actuator - Replacement Shock - DS12426

Jeff: Hello everybody. This is Jeff at etrailer.com. Today we're going to take a look at this replacement shock for the Demco Hydraulic Brake Actuators. This part will replace the shock in your Demco Hydraulic Trailer Brake Actuator. It is designed to fit the model numbers DA91, DA10, DA16 and the DA20 models. A few dimensions on this, the overall dimension from one end to the very other end, it's going to be right at 7".

Now when this extends out the full extension measurement will be 9-1/8". Distance from the center of this eye to the center of this eye, right at 6". And the same way if it's extended out it will be 8-1/8". Now the diameter on the smallest eye, which is right down here, is going to be right at 0.625" and on the larger eye is 0.89".But that should do it for the review on the replacement shock for the Demco Hydraulic Brake Actuators.

Ask the Experts about this Demco Accessories and Parts

  • How Do You Know if a Trailer Brake Actuator Shock Needs to be Replaced
    Shocks such as # DS12426 on brake actuators don't have a native, relaxed positioned. They will stay in place until acted upon by an outside force. You will know your shock is good if it is very difficult if not impossible to push in and pull out by hand. If you aren't straining and pulling or pushing as hard as you can then there is likely something wrong with the shock. Based on the problem you described it does sound like the shock is the problem.

  • Replacement Shock for Demco DA10 Hydraulic Trailer Brake Actuator
    The Demco Replacement Shock # DS12426 that you referenced is the correct part for your DA10 disc brake actuator; it also fits several other actuator models. If there is a mechanical problem within the actuator that is preventing it from compressing when your tow vehicle brakes then this should be evident when you disassemble the unit to install the shock. Since the trailer is only about a year old, you may want to refer the issue to your trailer dealer; the Demco DA10 actuator carries...

  • Fully Open and Fully Closed Lengths of the Demco Actuator Replacement Shock
    I went out to the warehouse and pulled replacement actuator shock # DS12426 to measure it. When fully opened it measured 8-1/8 inches from eye center to eye center and 9-1/8 inches long overall. When fully closed it is 6 inches eye to eye and 7 inches overall.

  • Replacement Shock for Demco Brake Actuating Coupler
    I was unable to find anything based on the information you gave. Without knowing the dimensions of the shock you need to replace, I can only help to narrow your options. We currently have 7 options and you've already determined 2 of them are not a fit. I've attached the link to all our other actuator shocks to assist. Each will have the dimensions available on their page. If you can't find the shock replacement, we do have the Demco Hydraulic Trailer Brake Actuator - Drum Brakes...

  • What are the Measurements for the Demco Actuator Replacement Shock # DS12426
    Presumably, the model number of the actuator will be stamped into the metal of the casing. This can wear down and/or get painted over after many years of service. If you cannot locate the make and model on your actuator, you may be able to go by the measurements. I went out to the warehouse and measured replacement shock # DS12426. The overall diameter is 1.662 inches (about 1-11/16 inches). The larger eye has an inner diameter of 0.89 inches (about 7/8 inches). The smaller eye has...

  • How To Fix Demco DA20 Surge Brake Actuator Slamming Brakes When Accelerating and Braking

  • Which Replacement Shock Damper for Demco DA10 Actuator
    The DA10 actuator you've got is a Demco, who have their headquarters in Boyden, IA and we do have a replacement shock damper available for that actuator with the Replacement Shock for Demco Hydraulic Trailer Brake Actuators - Models DA10, DA16, DA20, and DA91 # DS12426.

    I believe you are referencing a replacement shock for an actuator and from what you described it does sound like you are in need of a new one.

  • Replacement Shock Absorber
    I went through all of our shocks for trailer surge brakes and did not find an exact match. A similar one is the Demco # DS12426 replacement shock. This shock measures 6” eye to eye compressed, and 8-1/8” extended. In my research I found out MaeCo has been out of business for about 15 years. I could not even find a used copy of your shock online. Email me back if you would like to pursue specifying a new surge brake. I will need the trailer weight, brake type disk/drum and number...
