Hey guys, Kevin here with etrailer and today we're gonna be taking a look at etrailer's line ofreplacement magnet kits for electric trailer brake assemblies. Each of these replacement brake magnets fit a specific brake assembly. So you are gonna wanna knowexactly what size brake assembly that you have before you go ahead and purchase that replacement magnet. This specific one is designedfor 10 inch brake assemblies, which are typically gonna beon your 3,500 pound axles. So if you don't know exactly what size brake assemblyyou have, one good bet is to look at the capacity of your axle and that will typically getyou 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 istypically also worn out itself. This would be a good time to take a look at your brakeshoes, look at your pads, just see how worn in they are. In our case today, it wasn't an issue with the brake assemblybecause this is all brand new. It just happened to be justhow they ran that wiring for that brake magnet at the factory causing an issue whereit was shorting out. To begin our installationwe'll have to get to our brake assembly and todo that we will first need to remove our wheel which we'vealready gone ahead and done.
Then we're gonna pull out our pin and take our castle nut off. Then we can start workingout 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 startedtearing into the magnet. If we look at our wiring though, that's the major cause here. This was sitting here rubbingagainst our brake shoe and just eating up the wire, then the wire wasshorting and overheating.
On the back we're gonnahave 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, wecan pop our wiring through. So I've gone ahead and I cut that wire and worked out our littlegasket 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 insideof our brake right in here. And go ahead and just get thatoff 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 clipsthat 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 anotherreason why this magnet failed. So we're gonna just try andwork our screwdriver in there and just pry it up a bit and get it off. On your spring, you're goingto have a little portion where it's kind of bent down,got that 90 degree angle that's what's gonna clip intothis 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 thatback part, slip it through, popped right in no problem for us. Then we can go ahead andslip on our new brake magnet. Push that in a bit and we'llstick on our center clip. Now they do give you anew one with this kit. This is the only clip that you will get. So like I said, make sure youhold onto those other ones. I'll just push that in place and that's gonna keep our magnetfrom being able to pop off. From there we'll go ahead andwe'll sneak our wiring back and just up around andreplace 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 notgonna go nearly as tight as the previous one, justso we don't have any issues. Slightly squeeze that down justuntil it's kind of touching, we still want this to beable to move just a bit. Go ahead and tuck that inplace and put our clip back on. And just keep repeating that process as we work our way back. I'm gonna go ahead andreplace my gasket on here. Push that back in place and then I'm gonna stripthe casing back on this just a little bit 'cause we're gonna usingheat shrink butt connectors to attach to our wirescoming from our junction box. Put on some heat shrink butt connectors. Definitely recommend goingwith heat shrink just because these are gonna be outand exposed to the elements. You don't want a chance ofany water getting in there and corroding it and thenyour brake's not working. And it doesn't matter whichwire you hook up to which. So we can go ahead and we'll probably just slip this top onein and crimp it down. And repeat that with our other wires. Shrink down our heatshrink butt connectors. You can use a heat gunlike 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 thatwhen the axle kind of moves, you know, it's not gonnaget 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'llplace 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 sowe 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 justbend that back in place. Now we can go aheadand throw on our wheel. (tire clanging) Replace our lug nuts and thenthe cap over our spindle. Well, I think aboutdoes it for today's look at etrailer's line ofreplacement magnet kits for electric trailer brake assemblies. My name's Kevin, thanks for watching. .

Replace the worn or damaged magnet on your electric trailer brake assembly. Fits 10" assemblies with a 3,500-lb axle rating. Includes magnet, clip, and spring.The correct magnet at a great price. Nice it comes with a new spring and retainer, and the wires are at a good length to work with. Shipping was very reasonable and fast - thanks etrailer.com!
I like this company because they can be contacted with a real person on the end. On time delivery, correct part and instructions on paper and video.
Great information on your website to help with determining the right part for your trailer. The parts shipped quickly and had them installed on my trailer in no time. The parts are an exact match for my 2017 Grand Design trailer. They work perfectly and I will be using etrailer when I need to replace or upgrade my brakes in the future.
The part showed up quickly and worked perfectly. And the instructions were well laid out.
Replaced original brake magnets last year with these because the original one were causing an overload error code. These have performed perfectly. These were great for the price and working with retailer is always a pleasure.
Allen S - 03/18/2019Gwen did a great job at helping me and send me the correct product to get my trailer up and going again. I will always order from this company.
Thank you great job!
The items were received quickly and just as advertised. I ordered 4 magnets, but ended up only needing two. The fitment was the same as originals and the brakes now work.
I've purchased lots of small items from etrailer for many years. I always get the parts quicker than I get the opportunity to work on something. The fact that I can find the parts, with good descriptions, and photos, and compare items late in the evening, and order them at my convenience is a giant plus for me. The icing on the cake is their very competitive prices.
Bought parts for electric brakes on an equipment trailer I'm rebuilding this time.
Mr. C - 06/09/2018Replaced the failed coils on my camper and got functional brakes again. What more can I say but that they do the job. Make sure the wires clear all moving parts when installing.
works great thank you
Braking is weak since replacing hub/drum and magnets. Called tech help but contributed nothing that helped.
Mike L - 09/26/2018All parts arrived quickly and fit perfect! I bought a used car trailer few months ago and brakes quit working. Pulled drums and needed new magnets, it was missing spring on one side, prior owner must have got some bad service. E-Trialer hooked me up with all the parts, also ordered hub seals and grease and repacked bearings. Thank you !!!
The magnet kit was exactly what I needed (along with a separate order for the brake shoes and a springs kit). I had searched all over my local area, even going to several RV and Trailer parts stores, but they couldn't get me the parts I needed.
With just a little searching on etrailer.com, I got everything I needed, including new cotter pins!
I have already completed one wheel, completely replacing all the brake parts on my 1995 Wilderness Travel Trailer, and all the parts fit perfect - just like new. The parts came with instructions and warnings, and with the springs kits, I had everything I needed to get just-like-new brakes. etrailer.com made it very easy!
But why replace the shoes and parts rather than buy a whole new brake assembly? On some trailers, like mine, the brake assembly is welded to the axle, and would require completely new axles (at $2200) to replace the brake assembly. So the only option, in some cases, is to replace the shoes and other hardware.
One point of warning - the recommendation that comes with the parts is that you replace ALL MAGNETS and ALL SHOES on ALL WHEELS at the same time, otherwise you risk uneven braking. I didn't know this when I made my first order, so I had to order additional parts. But hey, if you are going to all the trouble to replaces the shoes and magnets and re-grease the bearings on one wheel, you might as well do all four right?
The hub and magnet developed a deep groove on the original equipment so needed a replacement. Since the brakes were still good all around, I went this route instead of a full brake assembly replacement. Installed ok.
great product and great price. spare part for my travel trailer.
The replacement brake magnet was fine, that just did not turn out to be the problem. A complete brake assembly replacement and drums turned was the fix. Parts also from etrailer, and it works great.
Needed trailer brake parts and etrailer had the best description of the products and prices. I like the fact that the parts are very well explained with dimensions so that you can order the proper part the first order.
Good shipping, hassle free transaction.
This product is still working well after a year of desert living. We use the trailer weekly, and the brakes still work just fine, even with all the dust, sand, and in rainy season, mud. We do clean the trailer regularly at a car wash to prevent dirt build up.
I ordered the 10" drum trailer brake replacement magnets and they not only fit and worked perfectly, but arrived before I had expected. etrailer has always stocked everything I've needed and at a great price. Their customer service and 'after sale follow-up' is the best I've ever experienced.
A great company to deal with.

Ordered a week ago and the product arrived without the spring or clip, so basically not useable for me until I get the replacement, which I'm now told will be another 4 days; I should have purchased locally, as I'll still be without brakes for going on 2 weeks.
Product was an exact fit. Magnet works in either polarity making install a snap. Trimmed excess wire and connected with heat shrink crimp connectors inside the drum.
Products ordered were as described and reasonable priced. I have ordered from Etrailer before and they are always a pleasure to work with.
Perfect fit an fast shipping had my trailer repaired and back on the road quickly
Product I ordered was exactly what was needed, and the shipping, even 3 days before Christmas, was fast, and I appreciate the service I received from etrailer.
It took a while to ship(8 days, tracking showed delivered in 6?), but the product was in good condition and corrected my problem.
