LIBRA Trailer Hub Drum Kits 5 on 4.5" B.C. w/ 10" x2-1/4 Self-Adjusting Electric Brakes for 3500 Lbs Axle

I purchased the non-self adjusting version of these brakes once before five years ago. They have performed flawlessly. They were mounted on a straight axle.For my drop axle, I ordered this set with self adjusting brakes. After installing, I could not reach adjusters for my first drive to bed the shoes, I drove a little short distances and activated the trailer brakes multiple times. Eventually, they self adjusted.As others have stated, you’ll need nuts, washers, and lock washers to mount them.

Bought these to replace the inoperative surge brakes on my boat trailer. They bolted on and self adjusted just fine in a few activations. Worked perfectly for my unknown brand 3500 lb axle.

Received in two packages. One had been resealed and was missing all of the hardware. No bearings, seal or lug nuts. Neither package included the nuts to mount to the axle which is a difficult size to locate locally. They are 7/16-20. I did locate some at a car parts store. Thought I would have to use lug nuts

the old brakes were untouched since 2008, too long i know. these were great, easy to instal about 30 minute per wheel, and they brakes now work like new.

I purchased two sets for these for my travel trailer with two 3500lbs Dexter Axles. They come individually boxed with brakes, drums, and vearing kit in each box. One of the boxes I received was damaged so I opened and inspected everything. I found that the grease seal and grease cap was damaged. I then inspected the three remaining boxes and everything else was ok. After messaging them about the damaged items they apologized for the inconnvenience and sent a replacement set right away. After receciving the replacement parts everything went smoothly. parts matched up to my axles and confirmed operation of all 4 brakes before putting tires back on. I then proceeded to Burnish the brakes to seat them in. Brakes work great. I would recommend these to anyone that knows how to properly work and diagnose trailer brakes.

Company worked well with me.Completely satisfied.Would be happy to work with them again in the future

I ordered these to convert a single axle trailer with dexter axle to electric brakes. The hub kit arrived in two boxes. When I opened the boxes and removed the hubs they were dirty inside and out with some sort of black grit. They don't come with the nuts for the backing plate 7/16 x 20 (hard to find). I installed the kit and adjusted the brakes however when the brake controller was activated the brakes didn't work, they would not lock the wheels up on gravel using three times the power I use for my travel (2 Axle) trailer. I think the magnets are faulty they would make a hum when the controller was activated. I used two different trucks to test with the same result. I had voltage at the brakes as high as 12.26V with no braking. I removed the hubs and reinstalled the original equipment to the trailer. I have requested a return and refund of my money.Update:Libra just informed me that they will not refund any money on parts that have been installed. How do you know if the brakes will work or are any good unless you mount and test them so I'm out $189.00 I used to trust Amazon. NO WHERE IN THE DESCRIPTION ON AMAZON DOES IT STATE THIS POLICY. Think long hard before you buy from a third party on Amazon. They did offer to ship out new magnets.2nd Update:I contacted Amazon A to Z guarantee they contacted the seller and arranged for me to get a refund minus a $35.00 restocking fee which is better then the total amount. If you have a problem with returns contact Amazon A to Z.

The nuts to hold the backing plates on were not included, and neither were new cotter pins. Reused the old nuts, but had to make a run to the store to get cotter pins. Besides that they seem fine.
