Troubleshooting No Brakes On A Trailer With TieDown 660 Hydraulic Actuator

Question

Question:

I have a boat trailer with a TieDown 660 Hydraulic Actuator. I am having the problem that everything on the trailer works but the hydraulic brakes. Will this work with that actuator as well?

Hello Josh. The TieDown 660 Hydraulic Actuator is a surge brake actuator. The Dexter Adapter Module # DX35FR is only for electric-over-hydraulic actuators, so this is not going to solve your problem. If the brakes are not functioning, I would have to suspect a problem with the surge brake actuator or potentially a brake line. I suggest inspecting the trailer and the actuator. You will be looking for any clogged or damaged brake lines. Also check your actuator to make sure it is moving fluid through the lines as it should. If your actuator needs to be replaced, I suggest the following:

Demco Hydraulic Brake Actuator - Drum - Zinc - 2" Ball - 7,000 lbs # DM72VR
