Use this hardware kit to mount (2) 10" brake assemblies on your trailer. Includes nuts and lockwashers. For assemblies with pre-installed mounting bolts.

Today we're going to take a look at the mounting hardware for 10" brake assemblies. This hardware will allow you to install two trailer brake assemblies to the 4-bolt brake mounting flange on the trailer axle. This hardware is designed to fit the 10" brake assemblies that already have the mounting bolts installed on the assemblies. These will work with electric or hydraulic brakes. It includes everything shown here on the table. It includes eight of the 7/16 by 20 nuts, and they do have a head size of 11/16. Here's a socket that has 11/16.
You can see it fits perfectly. It comes also with the eight lock washers. So, this would be all used to install the assemblies to your axle. That should do it for the review on the mounting hardware for 10" brake assemblies.

Use this hardware kit to mount (2) 10" brake assemblies on your trailer. Includes nuts and lockwashers. For assemblies with pre-installed mounting bolts.Great, fast shipping. I am confused because somewhere I read that if you buy the Right and Left set of brakes, the mounting nuts are free. Someone posted they had to buy the nuts. So, I ordered them too. P.S. they didn't send any extra nuts.
After some difficulty removing the nuts on the back of the brake mounting plate, I decided to just order new hardware and toss the old nuts and washers away. Replacement hardware arrived within two days, did not delay re-assy as weather rained. Just a note, I would recommend that e-trailer just include the hardware when you order replacement brake assemblies. 7/16 x 20 nuts are not that common.
The bag of mounting hardware only had the nuts in it. No washers in the bag as the photo indicates. For 16 nuts and bolts, I felt that this was overpriced when I ordered it, but I bought it out of convenience and to save a trip to the hardware store. Showed up without the washers so I had to go to the hardware store anyhow to get the washers. So I ended up paying $14 for 16 nuts that I could have just bought at the hardware store for $1 when I bought the washers. I don't know if the bag I received was packed wrong (no washers) or if the photo on the website was misleading?

Gosh, I am so sorry you ended up having to run to the store - you shouldnt have to do that! The picture is accurate - your bag was missing the washers. I have sent your information to our customer service team to have them contact you about the missing pieces and what we can do to make it right.
Well worth not having to make a trip to the hardware store. Very convenient.
SHOULDVE BEEN PUT IN A BAG INSTEAD OFBEING THROWN INSIDE WITH THE BACKING PLATES
Replacing Trailer brakes very easy with your brake assemblies. Thanks
The shipping was fast. I am expecting a second order I made for tires on aluminum rims in a couple days. I am looking forward to receiving them to upgrade my new trailer.
Worked good, but I would personally prefer nyloc locking nuts.
these arrived fine and as described - these don't appear to be zinc coated - I could not find anything in product description on rust resistance - suppose i will paint.

Worked out fine. Ideally for me these would be stainless for a boat trailer but I ended up painting to protect and should be ok.
Quality of product is good. The wrong size of lock washers were sent which is the reason for the 3 star review. Called customer service to let them know so shipping mistakes were not made in the future. With the old brakes removed, and the trailer on jack stands, I wasn’t going to wait 3 days for a new shipment, so I had to make a trip to the hardware store to complete the installation. Not going to raise a fuss over an $8 mistake.
Appear to be quality metal; matched up to my Dexter axles and hubs, no issues.
Arrived a couple days after the break kits and hubs; caused a small delay but no issue for me since did not need the trailer currently.
You'd think this should be standard to come with the brake assembly but it wasn't. I could have reused the existing but these are nice and clean and new.
Great service. Quick shipment on brake assemblies and tires. Competitive pricing. Found myself a new supplier.
Fit perfectly
Excellent quality nuts and washers. If doing brakes, there is no reason to reuse the old mounting hardware!

Everything is great! Just had our Band Boosters order new wheels and tires from etrailer!
Well, you may not see the actual brake controller in these shots, but I wanted to display just how much etrailer product was used to restore this old trailer. Re-decked the trailer, new wheel bearings, added brakes on all 4 with this brake controller and battery powered emergency disconnect... new rust protection, primer and paint, new lights and wiring all the way around, new wiring harness/box, and new tire carrier. Nearly all product except the decking and paint was from etrailer. the customer support was fantastic, I highly recommend this company!
I installed the brakes on the front axle of my boat trailer that carries a 21' fiberglass deep hull off shore boat. They work good as long as you have the controls set to the proper amount of gain. Even with the 5000# weight of my boat if I have the gain too high and hit the brakes too hard they will lock up. This is my second set for the same trailer. I found that no matter what you do not immerse them in saltwater. When I am going into saltwater I remove the brakes and put regular trailer hubs on until I am no longer in the saltwater environment. It's a hassle but I have never felt safe with surge brakes.
I couldn't find this item,in-stock, anywhere locally. I should've got it from etrailer.com fromthe start.
Ordered brake assemblies for all four wheels on a 3500 lb. 2-axle travel trailer with mounting hardware and heat shrinking wire connectors. Everything was very high quality and assembly took about 45 mins. per wheel. It also shipped in two days so I couldn't be happier about the transaction. Thanks.
the packaging was poor at best. nuts and washers were loose in the box hardly any packaging in the box and because of how it was packaged the insulation on some of the wires was worn away and wires were exposed. I wont be buying from them again unless I absolutely have to.

I understand your frustration with receiving the order in this manner. I will share this feedback with our shipping department and I will have our customer service team reach out to you.
New brake assemblies came with hardware so I bought these for nothing because the telephone specialist said I need them.

These parts work just fine
Never disappointed with etrailer! I changed the electric brakes before, so I knew what to expect. This RV has been in the Fla. swamps for over 10 years, so rusk was dominate on the nuts. A bit of cleaning, penetrating oil and all went well. New wiring, new brakes and everything works great.
Ian W shipped exactly what I needed and shipment arrived on time and well packaged. Hats off to ALL those involved in this process. I'll be back.
Hardwear kit not sure why it doesn't come with the backing plates? It did help with a nice new clean install.

In the product descriptions for the brake assemblies, we mention that the mounting hardware is sold separately.
The nuts fit the new backing plate but I only received three of the eight lock washers that were the correct size. The other 5 lock washers were too small
The lock washers were too small for the backing plate studs. The nuts in the hardware kit fit and everything else fit good. No huge problem. Brakes are installed.

It took me awhile to put the new self-adjusting brakes on the trailer. But, these nuts and lock-washers worked great.
