This review is not for jack ,it's for breakaway trailer system which I had to order twice 1st.broken hinges, ordered 2nd again one broken hinge,So I called your co. 3times ask for manager 1hangup, 1on hold ,1salesman transferred me to mgr. got answering machine. If you wouldn't get this junk from China maybe you would'nt have these problems .Apparently management don't to hear complaints.

I open the box to see, and I likey, it's well made. Haven't placed it yet, it was the last piece I needed for the big disc brake conversion and last of all the suspension upgrade. I'll show the pictures of some upgrade, and then once the disc brake system goes on, along with the breakaway system, with built-in charger.

All my parts arrived sooner than expected. The filter and trailer coupler are perfect. The wiring instructions for the Breakaway switch are a bit confusing, but a little research sorted it all out.



- PS50-85-320

Excellent product function. The only complained I have is that the plastic tabs of the lid broke almost instantly. I had to secure the lid with two large zip ties. Not a permanent solution but this part cant be purchased separately.



- PS50-85-320
by:

Part is well built and gives me the adjustability I needed for multiple applications for my hitches. The wheel had the correct offset I needed to fit my trailer correctly, and the breakaway kit was a great replacement for the one that was broken on the used trailer I just purchased. The universal trailer brake installation kit was just what I was looking for. Great quality and the ability to run either type of trailer wiring harness in one hookup. Great parts and great service!!!

Every thing was great with one exception, the instructions for the break away kit with the charger do not reflect the unit shipped. Instruction indicate 3 L E D 'S there are only two. There is no yellow to indicate if the unit is charging. But it works well after you get past trying to figure out why your unit isn't charging.

Product Died in a few short months. Battery wouldnt hold charge. it never went more than 45 days without use and then it just gave up. E-trailer said I had to pay return shipping so I just gave up and threw it out.

After getting a warning instead of a ticket I purchased this unit to put on my 25 year old stock trailer. In most states the law requires you to have a break away brake system on trailers. The quality is exceptional and extremely easy to install. The extra mounting options allow you to place this almost everywhere. The wiring instructions are more complicated than necessary. Just look at the front of the battery box and it tells you what wire goes to what.

Haven't had reason to use it yet. But easy to install. The best of this experience was the help I got from Cathy T. she didn't make me feel like a dummy. I thought she was very knowledgable about the braking system, I know I went away knowning more about trailer brakes.



- PS50-85-320

After a year later its still working as it should be. It holds a charge, like that there are Led lights to tell you what your charge is at I installed this on my 1969 Yellowstone Camper I restored and would buy again



- PS50-85-320
by:

bought this because of the battery charge indicator built into the unit. Needed to replace an older , inferior unit that did not have the ability to tell you the battery condition. This one has a heavy duty case with plenty of mounting options.

Hubs worked exactly as anticipated. Very quick shipping. Great products, easy to install and even videos of "how to" if needed.

Ask the Experts about this Pro Series Trailer Breakaway Kit

  • Trailer Brakes Lock Up After Installing Pro Series Push to Test Breakaway System
    It sounds like either the power wire for the battery is running to the brakes instead of to the switch or the pin that is in the switch of system # PS50-85-320 is pulled allowing the circuit to be completed which would send power to the brakes and lock them up. I have always found the installation instructions for this kit to be a bit confusing considering all of the diagrams in them, linked for reference. On the main unit the white wire is ground, blue connects to brake circuit from...

  • Can Pro Series Breakaway Kit # PS50-85-320 Withstand Exposure to the Weather
    With the Pro Series Breakaway Kit # PS50-85-320 the actual breakaway cable portion, shown in the linked photo, will typically be mounted on the side of the trailer frame. The battery/charger unit is best mounted in an out-of-the-way location where it will not be exposed to the elements or to the risk of impact from road debris but it certainly can be mounted in the open if necessary. The battery box is not formally rated as being weatherproof but it is built to withstand exposure in normal use.

  • Do All Pro Series Breakaway Systems have an Amber Indicator to Show the Battery is Charging
    Pro Series brake away kit # PS50-85-320 does have an amber light to indicate that the unit is charging. This is a feature of the models that come with a charger. If this is the system you have and the light is not coming on first make sure the 7-Way trailer connector has power on the 12 volt circuit. Also inspect all of the wiring in the system including the wiring for the breakaway switch and ground connections. A weak ground could cause the circuit to not be completed and it would...

    I can certainly help you determine what parts you need to add electric brakes to your 2015 Quicksilver 10.0 tent trailer. Based on my research, it looks like your trailer has a 2,000 pound axle. If that is the case you can use the following part numbers: Brake Mounting Flange - # 4-34 Brake Assemblies - # AKEBRK-2L left-hand side # AKEBRK-2R right-hand side Hub and Drums - # AKHD-545-2-EZ-2K for 5 on 4-1/2 inch wheel bolt pattern or # 8-173-16UC3 for 4 on 4 inch Breakaway Kit...

  • Correct Voltage Reading from Pro Series Trailer Breakaway Battery
    A standard trailer breakaway switch like # 2005-P does not have a circuit board but a unit like the Pro Series Trailer BreakAway Kit # PS50-85-320 does have circuit board for its battery tester. If this circuit board is corroded you need to replace the breakaway system since a voltage reading of 2V indicates the built-in battery charger is not functioning. A healthy and fully-charged breakaway battery should give you a voltage reading of at least 12V. Your existing battery may still...

  • Does HydraStart Vented Marine EOH Actuator HS381-8067 Include Breakaway Switch Battery?
    The HydraStar Vented Marine Electric Over Hydraulic Actuator for Disc Brakes - 1,600 psi # HS381-8067 you were looking at does not include the breakaway switch battery, so one must be purchased separately. This kit is compatible with a 5 amp hour breakaway battery kit like the Pro Series Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger - Top Load # PS50-85-320. I included videos of the products mentioned for you to take a look at.
