Video Transcript for etrailer Trailer Brakes AKBRKR-M12 Review

Today we're going to take a look at the replacement trailer brake magnet kit for 12 inch brake assemblies on 52,00 pound to 7 thousand pound axles. This part includes everything shown here on the table. It includes the magnet itself, the spring and the clip which is used to attach the magnet to the brake assembly. This magnet kit will allow you to replace the worn out magnet on your 12 inch trailer brakes and by just replacing the magnet it will save you time and money instead of having to replace the whole brake assembly. This part is designed to work with 12 inch brake assemblies on 52,00 pound or 7 thousand pound axles. If you notice the magnet is an oval design and this oval design will increase the efficiency of the magnet and it extends the life of the magnet itself. Just to give you an idea on the size on this, total width on this magnet is about 3 and one eighth inches, the height on it is right at about 2 inches and the thickness of it is right about 1 inch. Also if you notice, it has a sleeve on the first part of the wires that comes out of the magnet.

The reason they do that is when this is installed onto your brake assembly the wires go through the backing plate out the back so this is a protective sleeve that will protect the wires from rubbing up against the backing plate and causing damage so this sleeve will help protect the wires. If you notice it does have 2 black wires coming out and these are electric brakes so the 2 black wires, one goes to the brake feed, the other to the ground and it doesn't matter, either wire can be used for either function, there are 2 black wires so you can hook up either one either way. That should do it for the review of the replacement trailer brake magnet kit for 12 inch brake assembly on 52 hundred pound to 7,000 pound axles.

We used these parts to rebuild the brakes, drums, bearings and seals on two 24' deck over trailers. The install was easy, they fit perfect and work great. It is so nice to find the correct parts, helpful video's for installation at just a click of the mouse. We now have both of these trailers back on the road for many miles in safe working and like new condition with no issues sense the install was completed. Thanks so much to everyone at etrailer for the products, support and everything. My only regret is not taking photos. 732851

  • Replacement Brake Magnet Needed for a Hayes M144 or AL-KO K568111 Brake Magnet
    For your 12" x 2" brake drum you can use either our part # AKBRKR-M12 or the Redline # BP01-180 to replace the brake magnet on your Hayes/Al-KO brake assembly. Both magnets have 2 wires coming from them and it doesn't matter which wire is connected to which function. I have linked some review videos for you to check out.

  • Can Continuity be Tested on Trailer Brake Magnets to Determine if they Are Good
    We have an entire help article dedicated to testing trailer brake magnets that I attached for you to check out. You can test for resistance like you described. There is a specified range of Ohms that should be present depending on brake assembly size. If the assemblies are 10 or 12 inch the range should be 3.0-3.8 Ohms or if the assembly is a 7 inch assembly you'd need to see between 3.8 and 4 Ohms.

  • What is the Amperage Draw of a Brake Magnet on a 12 x 2 Dexter Brake Assembly with Round Magnets
    On a 12 inch brake assembly magnet, you should be getting 3.2 to 4 max amps at 12 to 13 volts. We have an FAQ article that covers testing brakes and brake magnets that should be helpful to you. I have included a link to it. Replacing the magnet is pretty easy. On the control arm that holds the magnet there is a spring. The hole in the magnet goes over the upright part of the arm and rests on the spring. Then, you replace the clip that holds the magnet to the arm. I made a short video...

  • Axle Kits with Electric Brakes to Replace Mobile Home Axles
    We do carry replacement magnets and other parts for electric drum brakes, including some older designs. I linked the replacement magnets we carry for 12 x 2 brakes, parts # BP01-225 and # BP01-180. However, mobile home axles are not intended for continuous use on a trailer. Mobile home axles are manufactured to be strong enough only for one use to transport the dwelling to its destination - just that one time. Mobile home axles are not safe for ongoing use on a trailer. But we do...

  • Replacement Brake Magnet for 12 Inch Dexter Braking Assemblies
    Yes, the Replacement Magnet Kit for 12" Electric Trailer Brake Assemblies part # AKBRKR-M12 which is the same as part KB12E-06 will work for you. The Dexter Trailer Hub and Drum Assembly part # 8-219-13UC3 that you referenced is for a 12" braking assembly so if this is the hub/drum that you have then the above magnet will work great for you.

  • Brands and Weight Ratings of Trailer Brakes That Can Use Replacement Magnet Kit AKBRKR-M12
    Electric brake magnet part # AKBRKR-M12 fits both left- and right-hand 12 x 2-inch electric drum trailer brakes. It is usable in brakes rated for axle capacities from 5200-lbs up to 7000-lbs. This will work on brake assemblies from most manufacturers, including AxleTek, Dexter, Lippert (LCI), IAC, and AL-KO. The magnets are not polarized so it does not matter which lead you connect as ground or hot.

  • Electric Trailer Brake Magnet Short Circuit Indicator on Brake Controller Comes On After Moving
    You said you checked the brake magnets. When inspecting them did you notice if the windings inside the magnets are showing? If so this is most likely the reason that the short is showing up on the controller when the vehicle is moving. This would mean that the magnets would need to be replaced. If you are seeing the short condition after you have been towing for a bit then the problem most likely lies inside a magnet. Brake magnets work best when they are warm and, if there is a problem,...

  • Are Trailer Brake Magnets Polarity Sensitive
    Brake magnets such as the Replacement Magnet Kit # AKBRKR-M12 on trailer electric brake assemblies are non-polarized. When installing an electric brake assembly, like the Right Hand 12" # AKEBRK-7R-SA, either wire can be used for the brake signal and ground wire functions. For the Left Hand assembly you will use # AKEBRK-7L-SA.

  • How to Test Electric Trailer Brake Magnets to Determine if They Need to be Replaced
    I would check the magnets for wear before going on to test them with a meter. If the magnets show abnormal wear or if you can see the windings beginning to show through the friction surface of the magnet then they will need to be replaced. To further test your magnets, first make sure the trailer is not connected when performing this test. If the trailer is connected, you run the risk of shorting out the brake controller or various other electrical components. To test the brake magnets...

  • Troubleshooting Intermittent Brake Controller Short While Travelling
    Intermittent shorts can be sometimes hard to find, but typically are due to a exposed wire on the shorting circuit that is in an area that allows some movement. Start at the connector for your trailer and work your way back to the assemblies looking for any cut or exposed wire and fix as needed. Where the wire goes from the frame of the trailer to the axle will be a good place to check as well as there is some movement there to allow the suspension to work. I attached a help article...

  • What Amperage Draw Does Brake Controller Look for on Trailer Wiring to Sense Connection
    Easiest way to fool a brake controller into thinking a trailer is connected is going to be by installing a brake magnet on the circuit as that's the "draw" it's looking for. For that you could use the part # AKBRKR-M12 and you'd be set. The minimum ohm resistance you'd want is 7.5-8.2 ohms which is the normal resistance found on a trailer with the smallest brake magnets offered. If you went the diode route that would be the size you'd need. I attached a link to a help article that has...

  • Troubleshooting Trailer Brakes that Short Out After 1/2 Hour Of Driving
    Sounds like the problem may be the magnets in the brake assemblies of your trailer. What you will you will want to do is check out the help article I attached that details how to test them so that you can find the bad magnet and replace as needed. Typically magnets don't go bad on newer trailers, but based on what you described it sounds like that's what happened.

  • Troubleshooting Trailer Brake Assemblies Where Only Closest Wheel Locks Up
    Have you checked the adjustment of the brake assemblies. They need to be properly adjusted in order for them to apply properly. Basically you want to tighten them to the point there is a light drag as you turn the wheel by hand. On electric drum brakes there is a star wheel at the bottoms of the assemblies that you can turn using a flat head screw driver or brake adjusting tool # W80630. Turning the wheel one way will bring the shoes closer in and turning it the other way pushes the...

  • Brake Magnets on Trailer are Only Showing 9 Volts
    If your brake controller is set to the maximum output then at the magnets you should be seeing 12 volts. If you get 9 volts then the voltage drop off could be related to the wiring such as loose connections or wire that is too small or too large (we recommend 12 to 10 gauge wire depending on the application, but usually 10 such as # 10-1-1). It could also be a weak ground. The magnets should be grounded to a clean, corrosion free bare metal surface near the magnets. And it could...

  • Troubleshooting Diagnostic Amperage on Prodigy P3 Brake Controller for Brake Magnet Function
    It does sound like your Tekonsha Prodigy P3 # 90195 has given you some diagnostic information that reveals you may have bad brake magnets. The magnets are bad if you have one braking axle based on the 9 amps recorded, but if you have two or three braking axles, then you are still within the proper range. I've attached an article to assist. If you braking is within amperage, then I recommend manually adjusting your brakes to ensure proper contact for braking. If you need to replace...

  • Trailer Brakes Not Working After Two Tire Blowouts
    It's possible that the brake assemblies themselves on your travel travel have been damaged. The overheating that most likely caused the two tire blowouts could have also damaged the brake magnets, which would lead to the brake controller reading no continuity (and having the same issue with a different controller). Since all the wiring and connections for the brake controller look good, I recommend removing the hub and drum assemblies on your trailer and checking for wear/damage to...

  • Brake Controller Trailer Disconnect Warning Light
    An often seen cause for the trailer brake controller to display a disconnect error message is a damaged or corroded connector on the trailer. This may have occurred during it's time at the shop or just didn't show up as a issue until after this work was done. Other common causes for this error message are a bad connection at the electric brake assemblies or a short on one of the magnets. There could also be damage or a short on the wire that carries the brake circuit. I recommend re-checking...

  • Testing Individual Trailer Brake Magnets or All Brake Magnets at Once
    If you are testing with the trailer connected to the vehicle (the first part of the FAQ, linked for reference) then the max amps at 12-13 volts for 4 brakes TOTAL should be 15-16.3 amps on 10 inch assemblies. This first section explains the process for testing all of the magnets at once. If you are testing each magnet individually, you should get 3.2-4 amps at 12-13 volts for 10 inch assemblies. If you are testing for resistance for an individual magnet you will be looking for 3-3.8...

  • Troubleshooting Draw Tite Activator 2 Brake Controller Flashing OL Code
    Magnets for electric brakes all function the same but are designed to work with different sizes and brands of brake assemblies-12 inch, 10 inch, etc. When replacing them, you need to get the right size that fits your brake assembly and your axle weight rating. The brand name is usually stamped into the hub/drum or it may be listed on a sticker/label on the axle and/or brake assembly. For example, a replacement magnet kit for 12 inch electric brake assemblies for a 5,200-lbs to 7,000-lbs...

  • Low Trailer Brake Voltage on a 2012 Ford F-350 with Integrated Brake Controller
    The out put on the trailer brake pin on the 7-Way is dependent upon how the brake controller is set. The power level of a brake controller can be set aggressively or lower depending on how heavy the load is you are carrying. The controller in the truck is proportional meaning that if you lightly put pressure on the brakes then it does not send that much voltage back. In a lot of proportional controllers, you actually have to be moving to get the proper voltage sent back when using the...

  • Trailer Brakes Hum But Do Not Work on 5th Wheel Trailer
    If the brake controller you are using is a proportional controller then it will not necessarily engage the trailer brakes unless it sense movement. Instead of testing it with the brake pedal, do the test with the manual override lever. Make sure the power output is set high enough as well. A brake controller needs to be adjusted every time you tow a different trailer or the weight on the trailer changes. If it is still not working then it could be a wiring or magnet issue on the trailer....

  • Can I Replace Just a Brake Magnet or do I Need to Replace the Assembly
    While it is possible to replace just the magnet like part # Replacement Magnet Kit for 12" Electric Trailer Brake Assemblies part # AKBRKR-M12 I highly recommend replacing the entire assembly. It proves very cost effective and can save you labor later down the road. It seems when one component goes the others are quickly behind it. Replacing it all with a kit like the Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies part # AKEBRK-6 is a great way to save headaches. I...

  • Can a Brake Controller be Used to Test Trailer Brake Function
    If the trailer uses electric brakes and the truck has a brake controller then you can use the brake controller to make sure the brakes are functioning properly. There are also ways to test the magnets using a multimeter such as # BTMT15. I have included a link to our help article that explains the testing procedures. Please note that a spinning wheel is much easier to stop when the wheel is off the ground. So even if the brakes are not operating like they should they can still stop the...

  • Troubleshooting Low Output Voltage from Trailer Brake Controller
    Your trailer brake controller should be able to output a full 12V signal when it is set for maximum power/boost. If you are measuring only 9.5V output then try testing right at the blue output wire at the back of the controller with a multi-meter like # BTMT15 while engaging the manual override control. Do this test with full power and boost selected on the controller. If you do not detect 12V here then the controller itself is bad. If you tested at the vehicle's 7-way then the issue...

  • SH On Prodigy Brake Controller But Trailer Brakes Work Fine with Different Tow Vehicle
    The SH error on the Prodigy series of brake controllers indicates that the controller is sensing a short. Since it worked fine with your truck the likely culprit is a dirty or corroded trailer connector on the RV. Make sure that the RV side and trailer side connectors are clean and free of corrosion inside where the wires attach and on the pins. Be sure to fix or replace any questionable wires as well. If this does not solve the problem you can test the brake controller using the...

    If your spindles are in good shape we can probably get you set up with new hub/drums and assemblies. First step though is to find out what spindles you have so we can see if we have a new hub that will fit it. I would need both bearing numbers for that or you would have to take exact measurements on the spindle where the bearings ride. I attached a picture that has more details on that.
