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.

  • 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...

  • Troubleshooting Electric Trailer Brake Assembly Magnets
  • We have an article to assist with checking your brake magnets like you are stating. The resistance will go down because the brake magnets are connected in parallel. Since the voltage doesn't change, the amperage draw needs to increase to power the magnets. This is Ohms law in action based on my research. You obviously already have a multimeter like # ALL648349 so if you determine based on the article that you need to replace magnets, I recommend # BP01-180 for 12 inch Dexter assemblies...

  • Which Magnet Fits etrailer 12x2 Electric Brakes for 5.2K to 7K Axles and Oil Bath Hub for 7K Axles
  • The magnet used in trailer brake assemblies # AKEBRK-7-SA is magnet # AKBRKR-M12 which you will see they have rated the same as the brake assemblies themselves. So since they are compatible with up to 7K axles you can say they are rated for 7,000 pound axles maximum. We have tow hub and drum assembly kits for 7K oil bath axles. First is # 8-219-9UC3-A and it comes with a 2-1/4 inch diameter seal. The other is # 8-219-9UC3 and it comes with a 2-1/8 inch diameter seal. The oil cap included...

  • 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...

  • Brake Magnet Recommendation for a 12x2 Brake Assembly
  • The strength of a brake assembly isn't based on the sensitivity of the brake magnet. The best way to pick out a brake magnet is to get one that is rated the same as the brake assemblies. Going with a higher rated brake magnet won't give you any additional braking power. It will only make the brakes seem more sensitive and hard to setup with a brake controller. If you have a 12 inch brake assemblies you would want the part # AKBRKR-M12. This magnet works for 5,200 to 7,000 pound 12 inch...

  • 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.

  • 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 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.

  • 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...

  • How to Wire Electric Drum Trailer Brakes
  • The magnet wiring of electric drum brakes for trailers is not polarized. This means that when installing an electric drum brake like # AKEBRK-7-SA (or even just a replacement magnet such as # AKBRKR-M12 ) you can use either brake wire as ground or hot. It does not matter which is used. You may care to refer to the two linked articles on electric trailer brakes and trailer maintenance.

  • Replacement Magnet Clip and Spring for 12 Inch Electric Trailer Brake Assemblies
  • For magnet clips we have a 4-pack, # BP19-001. Always good to have some spares. Magnet springs aren't available by themselves but you can get one in spring kit # AKBRKR-SP for 10 and 12 inch brake assemblies.

  • 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...

  • 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,...

  • Replacement Brake Magnet for 12 x 2 Inch AL-KO Electric Brakes on a 2009 Cougar 5th Wheel Trailer
  • You can actually use either magnet, # BP01-180 or # AKBRKR-M12, since your trailer is well past the 1988 cutoff for AL-KO assemblies. There is no advantage of one magnet over the other so I would go with # AKBRKR-M12 since it costs less.

  • 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...

  • 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...

  • 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.

  • Troubleshooting Short On Brake Output Circuit of Trailer that is in the Hub
  • It is most likely the brake magnets of your hub assemblies. To further troubleshoot them check out the help article I attached that covers this. I also attached a link to a page that has all of the brake magnets we offer. For example, if you have a Dexter 12 inch 7k rated assembly you would want the part # BP01-225 for a replacement magnet.

  • 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 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...

  • 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...

  • 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...
