Quick Tip: There's really not a whole lot to getting new drum brakes. If you've confirmed that all of the specs listed above line up with what you need for your trailer, you can be pretty sure these will work for you.

Automotive-Grade Brake Pads

The pads on these trailer brakes are made of the same friction material that you might find on a car's drum brakes. In fact, the material is SAE-N certified. So, not only does it provide high-performance braking, but it's environmentally friendly, too! With these brakes, your trailer will be good to go on any road throughout the United States and Canada.

The superior quality of these pads is also due to the fact that they're bonded to the shoes, not just nailed down. Riveted brake pads will always give you a screeching reminder to replace your brake shoes. That's because the rivets will scrape against your drum as the friction material wears down. You won't have that noisy problem with bonded brake pads. You'll also get a little more friction pad contact because there aren't any cutouts for rivets. And more friction means more stopping power.

A closeup shot of an etrailer drum brake shows a tapered brake pad.

These pads are also tapered, which should help to prevent any broken, crumbly bits of material from rotating inside the drum as the pads wear over time. Brakes without these tapers are more likely to create a jarring braking experience that could cause the brakes to stutter and lock up.

How to Manually Adjust Trailer Brakes

The more miles you put on your trailer, the more your brake pads will wear down. As they lose contact with the drum, stopping distances get longer and longer. To keep your brakes working great, it's important to adjust them pretty routinely. For this job, grab a floor jack and either a brake adjustment tool (sold separately) or just a standard flathead screwdriver.

Jack up your trailer enough to get the wheel(s) off the ground. Remove the adjuster plugs from the backing plate on the brake, and insert the flat end of the tool through the back of the assembly.

Screenshot from an instruction video shows how to manually adjust the the alignment on a drum brake

Push in on the star gear and lift it up. Keep doing this until the brake pads catch on your drum. When you can't spin your wheel by hand anymore, back the gear off by about 10 clicks by pushing down on the star gear. Does the wheel now spin freely (even if it sounds like the brake pads drag slightly on the drum)? Great! Then you're all done with that one and ready to adjust the rest.

Thoroughly Tested for Safety

These brake assemblies meet the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. These brake assemblies underwent extensive testing to measure stopping distances when braking. These brakes have also been tested by QAI for braking performance under real-world conditions to provide the most realistic scenario for the everyday tower.

How to Break In New Brakes

After you get these brakes installed and adjusted, you'll need to break them in. First, find a long stretch of road or a big, empty parking lot. Once you're there, set your brake controller to its maximum setting and get moving. Speed up to about 40 mph and brake to slow to about 20 mph. Repeat this 15-30 times. The goal is to get the brake shoes and magnet properly seated into your drum. You'll know you've done that when it feels less jerky (and more consistent) each time you apply the brakes.

Note: The brakes will be very hot after doing this, so after every 10 stops you'll want to wait about 10 minutes to let the brakes cool off before continuing. If you don't, you might cook and crack the pad material.

Assembly was a cake walk to install bad thing doesn't come with nuts had hard time finding new 7/16×20 next ups sucks got a day later



Its been a year now and still working like a champ


Product is fine, but they shipped it like crap. Stacked them brake pads together with no padding in between. Only packaging was some paper wrapped poorly around it all. I had to reassemble the units.


i replaced the trailer brakes on my horse trailer Instalation went smooth and easy. They are working perfect and the price was great



Brahes have been working perfect.I have used my trailer on steep windy mountain passes and the freeway witn on problems .


One of the left backing plates and one of the right backing plates got messed up in shipping, I think I can repair them but I may be reaching out if I am unable to fix them. the arms that old the magnet fell off and the shoes are not centered on plate


Absolutely great service. I have several trailers, and this will be my first stop for all my trailer needs. I would highly recommend this company to anyone. Highly trained staff very courteous and professional and helpful if you need a little guidance. Product was perfect. Replaced complete prepacked hub assembly and complete electric brake assembly. My trailer is same as new again. Thank you for your help. All my parts worked out great.





The parts were good, price excellent. Unfortunately the parts arrived in a flimsy box (it should have been put into a second box for shipping) that was crushed, the brake actuator was off on one set, both lower adjusters and springs had fallen out and the springs and adjusters were loose in the box and luckily did not fall out.


The staff at helped me choose the correct brake/axle parts and I received them promptly. After using the trailer brakes extensively for the last year, including a trip to southern Baja, I checked the bearings, seals, and brakes and found them all functioning properly and well within wear limits. I will buy from them again!


Brakes looked great out of box, installed without a hitch, everything fit perfect.

After several thousand miles of use brakes are still working great with no problems


This was my first experience with etrailer. I have no complaints regarding the telephone guidance I received or the products themselves. Everything went smoothly without any surprises. I will not hesitate to use etrailer again.



The wheel assemblies backing plates, brake components, hubs, drums, and bearings have performed without any problems. They have rolled over all sorts of road conditions for over 15K miles. If I had it to do over again I’d do the very same thing. They’ve been great on my 19’ travel trailer.


When I purchased this brake conversion package, I counted on the sales person to ascertain that I had everything needed. I was so disappointed and actually angry when I discovered that the studs on the back side of these brakes did not come with nuts and lock washers and in fact are an odd-ball size & pitch that is quite difficult to find at hardware stores. (7/16"-20) I have a very well stocked shop, containing most common hardware items, but not a single 7/16" bolt or nut...they simply aren't used in the USA to any degree. Hours wasted trying to locate nuts to to fit these studs left me no option but give a 2 star rating.

Oh wow, I have not heard of anyone not finding the seven sixteenth by 20 thread size at a local home improvement store. We do also carry them on site as part # BRKH10B.


I need to contact you concerning the order. This was supposed to be a set of 1 left and 1 right electric brake assemblies but I on recieved 1 box with 2 RH electric brake assemblies and no left hand assemblies. someone messed up in yiur shipping or a package has been lost. also i order 2 sets of 1 LH &1 RH assemblies. I will call in on this next week

Oh, no! I will have our customer service team reach out to you about this. I am sorry we sent you the wrong ones, but we will get you taken care of!


The Electric Trailer Brake Kit worked as advertised. With two thousand miles on the trailer I have excellent braking control. I did readjust the brakes after a few hundred miles and this improved the smoothness and braking control while driving through Arkansas backcountry roads.



The kit continues to perform perfectly


I’ve had these a year and I’m not real impressed. They are mounted on a drop axle stock trailer and are difficult but not impossible to adjust (adjustment slot sits behind the drop axle) The braking power of these has never been stellar. I can feel them work, but they are not braking as hard as they should.


The parts looks like good quality… but they came in the box all mangled up and apart. One of the brake assemblies was missing the screw adjuster sleeve.

Great place to buy. Super fast shipping, very nice follow up email after ordering, plus they have a great website that has e top notch search function, making it easy to find what I am looking for. Wish all online stores were this prefessional.


After a year of service, the brake kits are doing great. Living in the mountains, they get plenty of use, and I am very happy with my purchase.


Shipping was very fast. Parts arrived intact. Installation was a breeze. Would definitely order again. Thanks


The backing plates could come with nuts on the studs


Excellent help when I placed my order for camper trailer brakes. All questions and concerns were answered. Shipping was very fast, price was good and there was a lot of communication info during the whole process.


Parts and instructions were great. Shiping department needs to remember 5graid science class were if you put heavy parts in a box with a little paper they don't do well


One brake is broken and the other brake was the wrong part. The brake plates were packed horribly and the spindle was bouncing around in the box with brake plates.


I ordered brakes for my utility trailer. I have not ordered anything from etrailer in a few years but George spotted my order and upgraded delivery to expedite based on my pervious orders. Beyond the quality of their parts, the quality of their people make this my go to place. Best prices are just gravy on the biscuit.



The brakes are still working well after 1 year. Great quality product.


I have always had a Great Experience with your Trailer brake products. They are very well built and at the top of industry standards. As well as the Super pricing that I have found at I also love the thousands of videos that I can come to even when I am just browsing the internet to get answers to my questions. Thank you


Item as described. Perfect fit. Thanks Melissa for your help.


Disappointed, ordered these and nuts don't come with. Off to the store I go I guess

Yeah, these brake assemblies do not come with the mounting hardware. We do have it as a kit with nuts and lock washers separately as part # BRKH10B.

  • Troubleshooting Electric Brakes Grabbing on 2017 Aluma Cargo Trailer
    With brakes grabbing or locking near the end of a stop, it sounds like there are two possibilities.

The second and more probable possibility is that the trailer brakes need to be adjusted. The drag on your brakes is probably too high and that will cause your brake shoes to wear out prematurely because they are always in contact with the drum...

Then run a power wire to your trailer brakes and connect it to the wire which was not grounded (on either of the brakes) and run another wire from the power wire on that brake to the brake on the other side of the axle....
