Ask the Experts about this Demco Accessories and Parts

  • 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.

  • Trailer Actuator Replacement Shock is Gas Filled
    The Demco actuator replacement shock # DS12426 is a gas filled shock which provides equal compression whether going in or out. It will stay extended until its in use.

  • 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 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...
