  • Replacement Shock for Hydraulic Trailer Brake Actuator
  • 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. The correct one will be a replacement for your actuator, and I'll list the replacements we carry so you can select the correct one: - Replacement Shock for Titan Model 6 and 10 Brake Actuators # T1242600 - Replacement Shock for Titan Model 20 Brake Actuator # T0778400 - Replacement Shock Absorber for Titan Model 60 Brake Actuators # T2336200 -...

  • 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...

  • 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 Reliable Brand Actuator on a Mastercraft Boat Trailer
  • One of our replacement shocks might work for your Reliable actuator but we do not carry that particular brand so you would have to go by the measurements. We have several models including # 1844-2. This particular model fits Toledo brand actuators. When fully closed it measures 6-1/4 inches from center of hole to center of hole and when expanded, it measures approximately 8-1/4 inches from center of hole to center of hole.

  • 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...
