Video Transcript for etrailer Electric Trailer Brake Magnet Kit Replacement Review

Hey guys, Kevin here with etrailer and today we're gonna be taking a look at etrailer's line of replacement magnet kits for electric trailer brake assemblies. Each of these replacement brake magnets fit a specific brake assembly. So you are gonna wanna know exactly what size brake assembly that you have before you go ahead and purchase that replacement magnet. This specific one is designed for 10 inch brake assemblies, which are typically gonna be on your 3,500 pound axles. So if you don't know exactly what size brake assembly you have, one good bet is to look at the capacity of your axle and that will typically get you in the right direction of what your brake assembly is. Now, typically this isn't a part that you would normally want to replace.

Essentially, if this is kind of worn out then your whole assembly is typically also worn out itself. This would be a good time to take a look at your brake shoes, look at your pads, just see how worn in they are. In our case today, it wasn't an issue with the brake assembly because this is all brand new. It just happened to be just how they ran that wiring for that brake magnet at the factory causing an issue where it was shorting out. To begin our installation we'll have to get to our brake assembly and to do that we will first need to remove our wheel which we've already gone ahead and done.

Then we're gonna pull out our pin and take our castle nut off. Then we can start working out our outer bearing. Usually you can just pull on that, that'll kind of give you enough pressure to pop it right off. Set that down on a nice clean towel. And work the rest of our hub off.

Taking a look at our brake magnet, we can see kind of where it failed. Down here on the actual magnet itself, it's starting to flake off. You can see that it started to heat up and it really started tearing into the magnet. If we look at our wiring though, that's the major cause here. This was sitting here rubbing against our brake shoe and just eating up the wire, then the wire was shorting and overheating.

On the back we're gonna have this little clip. We're gonna go ahead and just pop it off. Just kinda sit here and slowly work it out 'cause we're gonna have to reuse it. I'm just using a flathead screwdriver. (metal clanging) And once we have that out, we can pop our wiring through. So I've gone ahead and I cut that wire and worked out our little gasket that we had there. I'm gonna slip that aside for now. And now I'm gonna go ahead and just pop off these three clips and then the one that's inside of our brake right in here. And go ahead and just get that off real easy right there. Make sure these are loose. Start pulling our wiring back. (metal clanging) And we'll also remove this spring. So your new brake magnet is not gonna come with these little clips that go along the brake shoe so we're gonna have to reuse those. And as you can see with this one, they way, way over-tighten that down so it actually cut into the wire itself. So that could be another reason why this magnet failed. So we're gonna just try and work our screwdriver in there and just pry it up a bit and get it off. On your spring, you're going to have a little portion where it's kind of bent down, got that 90 degree angle that's what's gonna clip into this little hole right here and hold this spring in place. So we're gonna try to get that on here. So I'm gonna take that back part, slip it through, popped right in no problem for us. Then we can go ahead and slip on our new brake magnet. Push that in a bit and we'll stick on our center clip. Now they do give you a new one with this kit. This is the only clip that you will get. So like I said, make sure you hold onto those other ones. I'll just push that in place and that's gonna keep our magnet from being able to pop off. From there we'll go ahead and we'll sneak our wiring back and just up around and replace our clips on. And I'm just gonna put 'em in the same spot where we already had our clips and sneak our wiring out the back. Get rid of some of that excess. Go ahead and slip on all of our clips. And this time we're not gonna go nearly as tight as the previous one, just so we don't have any issues. Slightly squeeze that down just until it's kind of touching, we still want this to be able to move just a bit. Go ahead and tuck that in place and put our clip back on. And just keep repeating that process as we work our way back. I'm gonna go ahead and replace my gasket on here. Push that back in place and then I'm gonna strip the casing back on this just a little bit 'cause we're gonna using heat shrink butt connectors to attach to our wires coming from our junction box. Put on some heat shrink butt connectors. Definitely recommend going with heat shrink just because these are gonna be out and exposed to the elements. You don't want a chance of any water getting in there and corroding it and then your brake's not working. And it doesn't matter which wire you hook up to which. So we can go ahead and we'll probably just slip this top one in and crimp it down. And repeat that with our other wires. Shrink down our heat shrink butt connectors. You can use a heat gun like I'm gonna do today or if you just had a lighter, you can go ahead and use that as well. (heat gun whirring) Next I'm gonna go ahead and just kinda zip tie this up just a little bit. I'm gonna leave enough so that when the axle kind of moves, you know, it's not gonna get pinched on anything but I also don't want it hanging too low where it's gonna get caught on anything. Now that our brakes back in place, we can go ahead and reassemble our hub. Just push that on, we'll place on our outer bearing. And we can just use our castle nut to kind of drive in our outer bearing. We're just gonna go until that's tight and then we'll back it off so we can get our pin in place. So got no movement out of the hub. A little tight from just my hands, so we're gonna back that off just a bit. Right about there. Still no play. So now we can stick in our pin. And then we'll just bend that back in place. Now we can go ahead and throw on our wheel. (tire clanging) Replace our lug nuts and then the cap over our spindle. Well, I think about does it for today's look at etrailer's line of replacement magnet kits for electric trailer brake assemblies. My name's Kevin, thanks for watching.

I know that this magnet is meant to be a replacement for 5,200-to-7,000-pound brake assemblies. What brand of brake assembly do you have? Can you tell me in more detail how the magnet is not a fit for you?



by:

etrailer's service and attention to the customer is next to none. Although they did not have an answer to the size of my brake hub for my PUMA 31RLQS, they spent the time trying to find the answer (12" BTW). They sent my replacement magnets to the RV campsite in Montana promptly so I could replace them. They fit the QAI brake assemblies perfectly. These particular magnets, although new, did look like pulls though. They are are working well and I am happy with them, and of course the service etrailer provides to their customers.



by:

Great product. Easy to follow directions and a helpful video to watch



by:

no magnets or magnet retainers



by:

Purchased these as replacements for the 12 inch drum brakes on 6K axles I have on my equipment trailer. Reason for the 4 star is because these are smaller than the magnets I took off. The original magnets were a 1/2 in. larger diameter all the way around. Time will tell on how much life I get from these "economy priced" magnets compared to the originals.



by:

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.



by:

Magnets work great. The ones on my trailer where the wires had dry rotted and broken loose where they attached to the magnet. I ordered these to replace the ones on my car hauler trailer that has 12" brakes that I rarely use. Since the price is so much less than anywhere I found.
Shipping was fast and items were packaged nicely.



by:

Great fast service and delivery. Install was a breeze with everything already installed on the back plate. The self adjusting brakes adjusted really nice. Applied brakes 8 to 10 times with the manual brake control on the controller while driving 20mph and that was it. Sorry forgot to take pictures.



by:

Great replacement for a failed brake on my race trailer and perfect fit. Installed easy and works as described.



by:

The installation was easy and straightforward— all necessary parts were included. The brake magnet is still performing flawlessly a year later!



by:

Product came promptly and fit as described. The help videos are a great resource. etrailer has always delivered as advertised. Very confident in using them.

  • Should There Be Power on the Ground Wire for a Brake Magnet
    There should only be power entering the brake magnets, not leaving them through the ground wire. I would first start off by regrounding each brake magnets to a new bare metal surface separately of one another and as close to the brake assembly as possible. Once the above has been completed and the problem still persist then it may be time to replace either the magnets or the entire braking assembly. In order to offer replacement brake magnets I would need to know the brand of brakes you...

  • 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....

  • 7,000 lb 12 Inch Electric Trailer Brakes Only Reading 7 Amps
    It's rare, but possible the brand new magnets are all bad. Assuming you have tandem axles and a total of four 7,000 lb, 12 inch electric trailer brakes, you should be getting 15.0-16.3 amps at 12-13 volts. It is more likely the magnet's ground wire is weak; it's really important to have the ground attached to a clean bare metal surface - no paint, dirt, etc. A bad ground can cause the circuit to be incomplete and cause the low amperage. Otherwise, if the magnets are indeed bad you can...

  • What is Difference Between Trailer Brake Assemblies KB10E-06 and KB12E-06
    The KB10E-06 # AKBRKR-M10 and the KB12E-06 # AKBRKR-M12 are similar magnet designs but they are intended for different applications/sizes of brake assemblies. The # AKBRKR-M12 is for 12 inch assemblies and the # AKBRKR-M10 is for 10. The temptation is to use the bigger magnet on the lower rated assemblies but doing so does not give you more powerful brakes, it actually will just make for harder to adjust brakes as it the magnet will be too sensitive.

    Your brakes will likely use the Replacement Magnet Kit for 12" Electric Trailer Brake Assemblies - 5,200 lbs to 7,000 lbs. part # AKBRKR-M12 and the Replacement Shoe and Lining Kit for 12" Manual-Adjust Brake Assembly - 5,200 lbs to 7,000 lbs part # AKBRKR-S-12

  • 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...

    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.

    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.

    I was able to find the Lippert Technical Service Bulletin 2023040017 which covers the issues on the axles installed for Brinkley RV's. The issue was the some of the hubs and brake assemblies were damaged and require full replacement. By searching for the bulletin above you will be able to see more information regarding the details and VIN's affected. It does sound like there is an issue with your trailer brake magnets as a single Magnet # AKBRKR-M12 should have 3.0-3.8 ohms of resistance...

  • 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,...

  • 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 be corrosion...

  • 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 # PT89ZR. 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...

  • 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 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.

    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...

  • 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.
