  1. Thomas Wilson

    No nuts and washers.: They fit and work great. But they do not include new nuts and washers.

  2. Joyce

    Quality and price: Product was what we needed.

  3. Dawg

    Work as advertised: Took about a week to get, were the cheapest I found. I used them on a 25’ covered utility trailer that I drove 1,300 miles and no issues. Definitely recommend

  4. David

    2nd time I’ve purchased these, and I’d buy again if I have another need.: Product is good. All new parts, already assembled. Packaged well. The shipping was @#$#@ horrible. FedEx cannot get their act together. Sent from Midwest, delivery location near Seattle. Could have rode a bicycle there and back in the time FedEx took to get them there, so as long as you’re depending on a claimed delivery time, you’ll be happy.

  5. Brian Musick

    Trailer Brakes: Fit of these brakes were spot on. Heavy duty backing plate and brake return springs were heavy. However not impressed with the magnetic contacts or the linings on the shoes. Will have to see how long they last.

  6. willard atwell

    easy install: nothing

  7. jesse

    Camper: I was missing one brake ajuster no problem used an older one from the one I had on

  8. Steve

    Missing nuts but good product: I had to go to Menards and hunt for nuts to fit the bolts. This product assumes the nuts for the old ones are the same as these new ones but this was not true for mine.

    Other than that worked perfectly.

  9. Robert C.

    Great value: My trailer has dual axles and I bought a pair of complete brakes at the local supply store and then discovered I needed the other axles brakes too. I went online and these were ALMOST half the price and look identical to the other ones.
    Saved a good penny and installed easily.

  10. Kevin Broeker

    Easy to install: Installed on my 16 ft. Trailer

  11. Rey

    Perfect fit: Great price, you can’t buy the brake shoes and hardware for this price

  12. Jonathan Truax

    shipping leaves a lot to be desired: brakes came with no hardware to install and finding 7/16 fine thread nuts are not easy. they also came disassembled due to poor packaging and probably poor handling. Thanks UPS……NOT. Once reassembled and installed the wiring was a breeze. work like they should

  13. A. White

    Great upgrade: Replaced hydraulic surge brakes. Same size, same fit, easy to install.

  14. Seals

    Installed easy.: So far so good, used them on my 18ft trailer, had read a couple of reviews that not all parts were connected but mine were all ready to install, haven’t used them yet with my Kubota 2650 super cab. Will update later.

  15. DJ C

    Does the Job: These brakes do the job. Decent for the price. They do not come with the 7/16 fine thread nuts FYI.
    I installed two sets on a 5,000 lb camper.

  16. Richard Petruzates

    Great replacement on time.:

  17. robert krivicich

    Great quality and performance: Great product oem quality for fit and finish, easy to install. Have used product before with no problems during trailer breaking. One more thing don’t forget to get new lock nuts to complete installation.

  18. ron fannin

    Really well built and complete.: Nice fit and really well built. Came completely ready to install and went on nicely.

  19. Randy Dietz

    Good value for the money: Magnet swing arm was not attached on one of the sets. But it was all there. Just had to undo the tension springs and put back on the pivot pin.

  20. William

    Great but no nuts.: Great product, was able to get them on fairly easy once I had the old ones off. Only complaint I have is they didn’t come with nuts to secure them. Finally found the right size at the hardware store (7/16-20).


    They fix &work ok: they fix &work &very good price

  22. An old geezer.

    Worth the price.: They work great.

    Great camper brakes: Worked great on our camper. Was a easy installation. Way cheaper than anywhere else.

  28. Alan W

    great product, great price, fast shipping: This is the only way to go to replace the brakes on a trailer. They dont take long to replace with this product because it is all preassembled

  29. MARS2023

    Quality electric brakes: Backing plates for electrical braking systems provided by this seller are excellent quality. Also not that the controller adjusted properly is the partner needed to make braking your loads safe!

  30. Mr Patient

    Great upgrade: I added these brakes to the trailer not originally with brakes. WOW what an upgrade, I tow with midsize SUV – AND this made stopping soo much better

  31. L.D.Disselbrett

    hell yes: I replaced the surge breaks on my boat trailer with these Best move I have ever done .

    Good value for the money: Good replacement. Didn’t come with new mounting bolts though.

  39. Stevo

    Good Parts:: This is a late review but the trailer is still in use and no problems. The Highton 10″ x 2-1/4″ Trailer assembly worked just fine, just add the LUBE and go….

  40. rah

  49. sam

    Five Stars: Easy install works well

  50. Rusty

    Five Stars: Direct replacement…

  51. YooperToast

    Five Stars: Bolted right up.

  52. MRM

    Cant go wrong on the price.: Keep in mind these do not come with the mounting hardware do you will need 7/16 Fine thread lock nuts. Another review mentioned this and was a lifesaver when it comes to aggravation. New magnets are around $50 and I had no idea what shape the rest of my stock equipment was in so I simply ordered these and spent the $30 extra. Install was a breeze minus needing to use a grinder to remove my rusty OEM stuff. I will say it may not be the worst idea to splurge and buy a set with drums if your stuff is rusty.

  53. Alan Simmons

    Perfect in every way: Replaced electric brake system on dual Dexter 3500# axles
    24′ 1973 Featherlite
    Perfect fit for
    the 10″x2-1/4″ drums

  54. Pen Name tom
