• How To Replace Surge Brake Shocks On Demco Actuator On 2004 Heritage Boat Trailer
  Thank you for the image of your setup Steve. I do not know what the manufacturer was thinking when they welded in the Demco Actuator on your boat trailer. With how it was installed there is no way for you to access that rear pin without drilling a hole through the frame. They should have installed either the Disc # DM8205222 or Drum # DM8202232 brake actuator which would sit on top of the A-Frame and allow you to access all components of the hitch. If you decide this is the best way to...

• Troubleshooting Locked Up Surge Brakes On A 1997 Stratos Tandem Axle Boat Trailer
  Hey Daniel, If the surge brakes are only locking up on one side that's typically a sign or a bad/stuck caliper (disc), blockage in the brake lines, or an overly adjusted brake assembly (drum). I would start by checking the caliper or drum assembly and then move on to bleeding the brake lines to check for an air bubble or contaminant. If you have drum brakes you'll want the hub./drum to spin but have a bit of drag on the brakes. Typically, I'll throw the wheel on with 2 lug nuts (hand-tightened)...

• 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 of...

• 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.

• Master Tow Dolly Chucking When The Brakes Are Applied
  It could be a couple of reasons why your MasterTow Dolly is chucking when applying brakes. I recommend checking the brake fluid levels and ensure it is not low. I also recommend checking the ball and coupler, and ensuring that you have the correct size ball, and that your ball isn't loose. Finally, you could have a partner ride alongside you and examine the chucking, it is possible something on your hitch is loose and could be causing this issue.
