After installing the reverse lockout myself, I had my hydraulic brake system bled at a local trailer shop. No problems moving the boat in reverse at the boat yard according to the yard manager. Boat is 8500 lbs. 471271

Used for 8000KM, could not get the switch to stop leaking brake fluid. I removed the switch to stop the leak and have not used the dolly much since. 470590

Very good product! It is brass so don't get crazy with a wrench tightening it. Just a little thread sealer and snug it a little is fine. I used it with an Atwood 6000 lb actuator and works perfect! I want to add that etrailer are awesome people to deal with! 455214

Do you have a question about this Accessories and Part?


  • Can Trailer Back Up With Demco Hydraulic Trailer Brake Actuator # 8605001 Installed
  • The Demco Hydraulic Trailer Brake Actuator # 8605001 that you purchased doesn't have an electric or manual lockout integrated so to back your trailer with the actuator as-is would mean you need free-backing brakes on your trailer. You still have the option to add an electric solenoid though with part # DM5837. This installs by threading it into your master cylinder and then allows you to back your trailer up when you connect the wiring to the reverse light circuit on your tow vehicle/trailer....

  • Demco Hydraulic Brake Actuator for Drum Brakes with Lockout
  • The Lockout Solenoid Kit # DM5837 you referenced is not designed to fit the DA86 model of Demco actuators, which is the part # DM8608601 you referenced. There are a couple of alternative options for a similar hydraulic drum brake actuator with a lockout that I recommend checking out. The first is the Titan Zinc-Plated Brake Actuator - Drum - Multi-Fit Ball - Bolt On - with Lockout - 7K # T4339720 and the other is the Demco Hydraulic Brake Actuator w/ Manual Lockout - Drum - Zinc - 8"...

  • DA91 Demco Disc Brake Actuator for 2-5/16 Hitch Ball with Electric Lockout Needed
  • The DA91 Demco surge brake actuator that you are looking for is part # DM8750311. This has a 2-5/16" coupler, comes with an electric lockout, is designed for disc brakes, and has a weight capacity of 8,000 lbs towing and 800 lbs tongue weight.

  • Will the Demco Solenoid Kit # DM5837 Fit Demco Hydraulic Brake Actuator # DM8759812
  • Since the Demco Hydraulic Brake Actuator # DM8759812 is a DA91 actuator the Reverse Lockout Solenoid Kit # DM5837 will fit. I confirmed this with my contact at Demco.

  • Best Replacement Reverse Lockout Solenoid for Demco Hydraulic Brake Actuator # DM8509612
  • We do have a replacement reverse lockout solenoid for the Demco Hydraulic Brake Actuator # DM8509612, but the Replacement Solenoid Valve # T4748800 that you referenced is not designed and has not been tested to fit the Demco actuators. Instead you will want part # DM11993 for just the solenoid or part # DM5837 for the kit that includes the solenoid cover. These are designed specifically for the Actuator # DM8509612. I have attached a link to an installation video of this solenoid...

  • Troubleshooting Boat Trailer Brakes Locking Up in Reverse
  • It sounds like your reverse lockout solenoid is not working properly. You can use the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 or the slightly better designed Demco # DM5837. You will wire one side of the solenoid to the reverse light function on your 7-way and then the other wire will be grounded to your trailer frame. I've attached a couple videos of installations to assist. I've attached a photo of the 7-way pin locations to assist.

  • 5-Way Adapter Recommendation for a 2008 Mazda CX-9 For Surge Brake Trailer
  • If you don't mind a little bit of wiring I have a much cheaper solution to activate your reverse lock out solenoid. You would just need the part # 47515 that will adapt the 4-way to a 5-way. Basically you just plug this into your 4-way and then wire the 5th circuit up to the reverse light circuit and the reverse lock out solenoid will activate like it should. I attached an install video for this harness for you to get an idea how it would install on your vehicle.

  • Hydraulic Line Size Used with Demco Reverse Lockout Solenoid DM5837
  • The Reverse Lockout Solenoid in the Demco kit # DM5837 installs in line with your master cylinder and a standard 3/8" hydraulic line, like # bh-3mfs-24. The # DM5837 is designed to work with Demco models DA10 and DA91 hydraulic trailer brake actuators.
