Today we're going to take a look at the mounting bolts and the hardware for 12 inch brake assemblies. Now this hardware will allow you to install two trailer brake assemblies to the five bolt brake mounting flange on your trailer axle. This hardware is designed to fit 12 inch brake assemblies that do not have the pre-installed mounting bolts. It will work with either electric or hydraulic brakes. It includes everything laid out here on the table. It includes 10 of the one and a quarter inch long by three eighths inch diameter mounting bolts. and the head size on that is a nine sixteenth. Heres a nine sixteenth socket, you can see it fits perfectly.
Also comes with 10 of the three eighths inch by 24 size nuts, and they are the same size, nine sixteenth, and also the 10 lock washers. But that should do it for the review on the mounting bolts and the hardware for 12 inch brake assemblies.

Great fit and quality for my 38 year old trailer I built with my Grandfather from the ground up.
I needed to upgrade my boat trailer from free-wheeling spindles to electric brakes because my new tow vehicle has a 5,000 pound tow rating only if the trailer has brakes. I chose the Dacromet coated brakes assemblies, this mounting bolt kit and the galvanized hub and drum kit. This mounting bolt kit seems to be excellent quality hardware that fit perfectly. I torqued to 35 lb-ft.
Hardware was OK but I reused my original hardware because it was in good condition and I prefer the captive star washer nut to the separate nut and split washer.
In my opinion, lock nuts would be better. That is why I give only four stars. Regardless, the bolts, washer, and nuts were in new condition and none were missing. No threading problems or torque problems.
Glad I purchased these when installing the new brakes, old nuts and bolts were corroded made the installation easier and added assurance of new hardware

Paid for this but the hardware was included with the other components.
Not a big deal just not needed..

Let me get your information over to our customer service department for them to further assist you.
I never received the bolts
Product packages packed very well and delivered on time
I purchased these brake assemblies to replace the old electric brakes on one axle of my 1963 vintage twin axle trailer. Best thing I ever did. The electric brakes were relatively simple to install and have been working extremely well. These new brake assembles have logged more than 8,000 since they were installed and have worked well with the brake controller and break-away cable system I also installed. I am very happy with this product.
Direct replacement!
I ordered 4 non-self adjusting brake sets and recieved 2 self adjusting right sides and 2 non-self adjusting left sides. I needed the project to be complete and I installed them. When i tok the out of the boxs, there was some rebuilding as things were out of alignment from shipping. Initial adjustments on both sets was a little more time consuming because of the lack of large adjustments, but once set they are great. The electrical hook ups were easy. They stop my 5000+lb camp trailer just fine. Finally, hardware being purchased separately is annoying. They should be packaged together and the hardware should be free with purchase of the brake sets.
Nice job "e-Trailer"; received this "heavy" order very promptly; did not expect it so quickly in view of how other retailers/ manufacturers/ on-line businesses are behind in fulfilling orders. Packages (3) came all intact, well packed and product received in great condition. The order included:
> 5-Leaf Slipper Spring w/ Hook End for 6,000-lb Trailer Axles (2)
> U-Bolt Kit for Mounting 8,000-lb, Round Trailer Axles - 8" Long U-Bolts (2)
> Tandem-Axle Trailer Equalizer Kit for 2" Slipper Springs - 10-1/8" Long Equalizers (2)
> Dexter Nev-R-Adjust Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies - 6K (2)
> Mounting Bolts and Hardware for 12" Brake Assemblies (2)
> Bearing Buddy Bearing Protectors - Model 2441SS - Stainless Steel (Pair) (2)
> Bearing Kit, 15123/25580 Bearings, GS-2125DL Seal (4)
> Optronics LED Combination Trailer Tail Lights - Submersible - 40 Diodes - Driver and Passenger Side.
These items are being utilized in the total suspension replacement of a 10,000 gvwr tandem axle trailer. Good sized job for a DIY'er. I expect that it will give my JD 2038 tractor a smooth and safe ride as it is towed/ hauled down the highway.
Thank you.
I would/will strongly recommend to a friend/relative or associate.
( I'd take a picture of the "project", but there is a vicious rain storm occurring outside; perhaps one or two pics to follow at a later time).
Just one of the many satisfied customers with the company etrailer. I have used this on line site to refurbish my used boat trailers over the last 10 + years. During this pandemic I sort of let my trailer sit around and just wait until the end is near to react and make the trailer road worthy. After 3 years in out of salt water (mostly in) you might get this. After acquiring new brakes and drums from etrailer it’s back to the salt water again. Thanks for the essential workers at etrailer George, Savanna, and Carol. Cheers
When you replace everything from the axle spindle out, why would you not replace the brake assembly mounting plate bolts? The quality was good and we felt confident that the correct grade of bolt was used. Price was minimal when compared with the possibility of bolt failure if the old bolts or hardware/farm store bolts were used.
I rebuilt an old boat trailer that has been sitting outside for 10 years. It was in really bad shape & I could not read any of the bearing numbers, all had had was the dimension of the hub & the old bearings. Stacey A. at etrailer was very helpful in getting the right parts I needed & best of all when I got my parts they all fit. The brake kit was great just bolt them on. Very quick shipping & great service.
Thanks
Brakes are on and looking/ working great. A much improved self adjust system than was the OEM brakes.
I could see the quality right off. Now no worries for another ten thousand miles. Thanks for your help etrailer

Still going strong....
I was initially concerned about finding the right parts as the trailer was fairly old. etrailer had just what I needed. The website is so elegant. I was able to find the right parts quickly and with comparative options to make a final selection. The how-to videos are great. This made installation a little more comfortable. Especially when you do not perform this type of work every day. The parts were of high quality and are working as expected. I highly recommend etrailer for any of your trailer needs.
nice complete set of backing plate fasteners.
saved me from pc mealing something together from the hardware store.
Excellent quality fasteners for the price. Bought thsesin case I needed to replace the entire brake assembly on my car hauler trailer. Did not have to replace them but will keep these for other projects that may com along. Will definitely order from etrailer when I need other items.
If a new RV isn't going to have disk brakes, then they should all come with these. Pretty straight forward replacement. I didn't get new drums, just had the old ones turned.
If you replace the brake assemblies it is always easier to use new hardware. Better than cleaning the old rusty ones, and safer.
Turned out that my axles had studs and not bolts. I did replace the nuts and washers though. I figured it was better safe than sorry to order new hardware.
I received some great advice and help from Leeza in selecting the correct product for my needs. Without serial numbers or identifiable model numbers on my existing trailer parts, she was able to determine the correct parts for my particular trailer needs (on a 25 year old trailer.whose manufacturer is no longer in business).
I received the parts in the time span indicated upon ordering, and they fit perfectly.
A good experience all around.

After one year these bolts are tight and free of any rust or corrosion.
