  • Replacement Breakaway Pin and Cable for Bright Way Trailer Breakaway Kit
  • The Bright Way Trailer Breakaway Kit with Switch, 12V, 5-Amp-Hour Battery, and Charger # 3802339 isn't a guaranteed fit with the Hopkins # HM20051. Instead I recommend using the Replacement Cable and Pin for Bright Way Trailer Breakaway Kits - 42" Long # 3802350.

  • Replacement Breakaway Cable for Trailer with Dexter Brakes
  • I do have options for you but just because the trailer has Dexter brakes does not mean it will also have a Dexter breakaway kit. If you want to replace just cable and pin then I will need to know the brand and model of your breakaway kit which can be found on the top of the switch. That said, breakaway kits are universal so it would be easiest to just replace both the switch and cable/pin with the Replacement Breakaway Switch with Cable and Pin part # K71-691. There are only two wires that...

  • Replacement Breakaway Switch for Trailer
  • There is some wear and tear from driving with your breakaway kit engaged, but it is likely that the switch is all that will need to be replaced. The brake shoes were working hard and most likely wore down faster than they normally would, and I recommend pulling a hub to do a visual inspection to ensure there is still enough brake pad left. As long as there is some brake material left and it doesn't have a smooth glade on the outside of the pad, you don't need to replace them. If there...

  • Trailer Breakaway Kit with Charger for Trailers with Electric Brakes
  • The breakaway kit pin when removed sends 12V power directly to your trailer brakes. Because you didn't have the pin in, the breakaway kit did exactly what it was designed to do for the trailer brakes. The battery box having damage sounds like the circuit board overheated and will need replaced. This definitely isn't normal operation and I don't know the cause of that. I recommend replacing the entire unit with the Hopkins Engager Push-To-Test Trailer Breakaway Kit w/ Built-In Charger...

  • Replacement Breakaway Switch For A Brightway Group Trailer Breakaway Battery
  • To replace the breakaway switch for your Brightway Group Breakaway Battery you'll just need the Replacement Breakaway Switch for Bright Way Trailer Breakaway Kits # 3802348. This is going to come with 4' of wire that you can run out to the battery and junction box, but you could honestly just cut most of it off and splice it right in where your wiring is now to save time and labor. You'll want to use some heat shrink butt connectors # DW05744-5 to protect your connections though.

  • Replacement Breakaway Pin and Switch for Trailer with Electric Brakes
  • It sounds like the pin out has now drained the breakaway battery and that is why your trailer is rolling free. I recommend the Replacement Breakaway Switch Trailer Breakaway Kits # 3802348 to replace your pin and receiver and then charge your battery. Make sure to pull the pin to test function from time to time. A working pin and receiver should allow you to pull and reinsert the pin without issue so you can test it regularly.

  • Recommended Replacement Cable and Nylon Pin Assembly for an ECSO Breakaway Switch
  • Although we do not have that specific brand of breakaway switch, the lanyard pin that you are talking about is basically universal on every breakaway switch. You should be able to use the Replacement Cable and Pin for Bright Way Trailer Breakaway Kits # 3802350 with your ESCO breakaway switch. With that being said, if you want to be sure, you can just replay the switch with # 3802348 since the switches are universal, this is sure to solve your problem.

  • Replacement Breakaway Kit for 2013 McClain Boat Trailer
  • The Hopkins Engager Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger - Side Load # 20099 will work even when mounted as you mentioned. There is a top load version # 20400 that mounts to the trailer rail from the side. The difference in mounting is not a big issue but rather a preference. The Hopkins Engager is an excellent system that is a top selling replacement for many factory breakaway kits. I've attached some videos to assist.

  • Can Case/Charger be Replaced on Bright Way Push-to-Test ICU Trailer Breakaway Kit
  • There are replacement parts for the Bright Way Push-to-Test ICU Trailer Breakaway Kit with 0.5-Amp Charger and 5 Ah Battery part # BW94FR but the case/charger is not one of them. Therefore, if you want to upgrade you'd be looking at an entire new system but as the case and charger are the bulk of the kit, you aren't wasting much money. Furthermore, not all breakaway batteries fit in this case so you need to be sure you're using the one that comes with.
