Video Transcript for The Low-Down on the Mounting Bolts and Hardware for 12" Brake Assemblies

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.

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.

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

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

Continues to work as before

Function, Fit and finish are all absolutely perfect. I just got everything reinstalled to include hubs, actuator and brake lines.



by:

Great fit and quality for my 38 year old trailer I built with my Grandfather from the ground up.



by:

Over priced,missing parts.



by:

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.



by:

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....

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.



by:

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

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.



by:

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).

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



by:

Great product!



by:

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.



by:

Good product



by:

Worked as they should.



by:

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.



by:

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.



by:

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.



by:

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.



by:

Recommend when installing new backing plates. Money well spent. Not much more to say about nuts bolts and washers. Direct fit and full set.



by:

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.



by:

Great customer service, & friendly. Saves me money, time & quality products.

If you replace the brake assemblies it is always easier to use new hardware. Better than cleaning the old rusty ones, and safer.

  • How Can I Identify an Axle Without a Sticker?
    Thank you for the pictures! It looks like you've got some sort of square drop axle on your trailer and if you can't find an identifying sticker, I can still help you figure out what you've got so that you can make the swap to electric brakes on your trailer. It looks like you've got 6 bolts on the wheels, which can help narrow down our search, but we'll need to know what size the brakes on the trailer are and if possible, what size (or number) the inner and outer bearings are on the hubs. If...

  • Replacement Axle for 2018 Grand Design Imagine 2150RB
    Grand Design lists an 86-1/2" 3,500 lb axle for your Imagine 2150RB. The next size up would be a 5,200 lb axle like the # e45GR. This has the same 86-1/2" hub face measurement but the spring seat is different. You will need to cut off the spring seats and weld on # TRSS300 to match your current 68-1/2" measurement. The CE Smith U-Bolt Kit for Mounting 5.2K to 7K, Round Trailer Axles # CE23003 will be required as well. For a hub and drum assembly you can use the # AKHD-655-6-EZ-K. These...

  • Replacement Brake Shoes For Electric Brakes on Lippert 5,100 lb Axle
    Hi Aaron, Appreciate all that info, and a Lippert 5,100 lb axle will use 12" x 2" brakes, so for brake shoes you'll need the Replacement Shoe and Lining Kit for 12" Manual-Adjust Brake Assembly # AKBRKR-S-12. Like the title says though, these are for manual-adjusting brakes only, so if you have self-adjusting brakes on your trailer you'd have to replace them with Electric Trailer Brakes - Self-Adjusting # AKEBRK-7-SA and Mounting Hardware # BRKH12.

  • How to Find Replacement Drum Brake Assembly for Boat Trailer
    I can tell you exactly how to find compatible drum brake assemblies, though I took a look and could not find any type of reference to Dico 40511. To determine the brake assemblies that will fit your 2002 Escort boat trailer, you need to know your axle's weight capacity, your mounting flange bolt pattern and the inside diameter and depth of your drum. For example, Hydraulic Brake Kit # AKFBBRK-35-D are rated for 3,500 lb axles, have a 4-bolt mounting flange pattern and measure 10" diameter...

  • Replacement Hub/Drum and Brake Assemblies for Dexter 5,200 lb Axle
    Hey Stephen! I see you already ordered replacement parts from our site. I double checked with Dexter, and the Dexter Trailer Hub and Drum Assembly # 8-201-5UC3-EZ fits as long as you have a 6 on 5-1/2 bolt pattern. However, you will want to swap out that grease seal for the # 10-36 to match your spindle. The etrailer Electric Trailer Brakes # AKEBRK-7-SA will also work, if you need hardware # BRKH12 is available separately. Any big trips coming up with your Cruiser?

  • Recommended Brake Assembly Backing Plate Bolt Installation
    The attachment bolts for a 5-bolt brake assembly should be torqued to 30-50 foot/lbs. This will ensure your brake assembly # AKEBRK-7-SA is secured correctly. If you don't have a torque wrench, I recommend the Powerbuilt Dual Drive Torque Wrench - 3/8" and 1/2" - 10 to 150 ft-lb # ALL944001.

  • Recommendations For Upgrading to Timbren Heavy Duty Axle-Less Trailer Suspension
    Timbren axle-less trailer suspensions are a great way to upgrade your trailer. They provide a smooth, quiet, safe ride and allow you to maximize your ground clearance. You will not be able to match your truck hubs because trailers and trucks are different and are not interchangeable. Which system you need and what components will depend on your trailer's weight capacity, bolt pattern, and how you are using it (for example: off-road). For example, the 3,500 pound Timbren Axle-Less Trailer...

  • How do I Correctly Measure Drum Brakes?
    When measuring the brake drum, you measure the interior diameter on the drum. I have attached a photo to help during the measuring process. If your brakes are 7 inches part # AKEBRK-2 works for your application. You also need hardware part # BRKH7 If your brakes are 10 inches part # AKEBRK-35-SA works for your application. You also need hardware part # BRKH10B If your brakes are 12 inches part # AKEBRK-7-SA works for your application. You also need hardware part # BRKH12

  • Self Adjusting 12" Brakes for a 5,200 to 7,000 Pound Axle
    Hi Craig! What you are looking for is the etrailer Electric Trailer Brakes - Self-Adjusting - 12" - Left/Right Hand - 5.2K to 7K # AKEBRK-7-SA. As you are needing 2 rights and 2 lefts, you will need to get two sets of the # AKEBRK-7-SA, but it is self adjusting and works for 5,200 to 7,00 pound axles (12" x 2"). I do have to say these do not include mounting hardware though, so if your hardware is looking a little worse for wear, you will want to replace it. We that is the Mounting Bolts...

  • Self-Adjusting Electric Brakes For 2022 Grand Design Momentum 350G With 7k Axles
    Hey Don, The 17-1/2" wheel listing is just a guideline for hub size, because wheels that are too big have a hard time mounting to some hubs due to the lack of surface area. So it won't affect the fit of brakes, and because you have the 7k Dexter hub and drum on your 2022 Grand Design Momentum 350G, here's what you'll need: - Electric Trailer Brakes - Self-Adjusting # AKEBRK-7-SA - Mounting Bolts and Hardware # BRKH12 These brakes have an E-coating on the backing plates, and the hardware...

  • Recommended Replacement Straight Axle for a Carry-On Trailer
    Hey Paul, thanks for dropping by! I actually spoke with Dexter and they let me know that you have a 3,500 lb axle with a 93" hub face and 80" spring seat measurement so you could use the Dexter Trailer Axle Beam with E-Z Lube Spindles # 8327864. The only issue I'm running into is that there are no hubs with a 5 on 4 1/2 bolt pattern that fit this axle. To use this axle as a replacement you'd also need to then swap your hubs and brakes with the Dexter Trailer Hub and Drum Assembly # 42866UC3-EZ...

  • Will the 6,000 lbs Dexter Nev-R-Adjust Electric Trailer Brakes Work on a 5,200 lbs Axle?
    They sure will Thomas. The Dexter Nev-R-Adjust Electric Trailer Brakes - 12" - Left/Right Hand Assemblies item # 23-458-459 are exactly what you need for your 5,200 lbs axles. These 12" x 2" drum brakes will bolt directly to your Grand Design's 5 bolt brake mounting flange. This set comes with both left and right brake assemblies. If the hardware on your current brakes is the original set, I recommend replacing them when you swap out the brakes. You'll need the Mounting Bolts and Hardware...

  • Replacement Hubs and Brakes for 2018 Kodiak Cub 175BH
    Hi Jon; the parts you picked out will work as a replacement. The Dexter Trailer Hub and Drum Assembly # 8-201-5UC3-EZ is an 8-201 hub with a 6 on 5-1/2 bolt pattern. The etrailer Electric Trailer Brakes # AKEBRK-6 are compatible with this hub and drum assembly. However, I recommend getting the # AKEBRK-7-SA instead. These are self-adjusting so you won't have to worry about adjusting your brakes over time. If you need new brake mounting hardware you can use the # BRKH12.

    Hey Anthony! I would be happy to put that together for you. The Timbren Axle-Less Trailer Suspension # TASR5200S03 is the 5,200 lb version with a 4" lift. For trailer brakes you can use the etrailer Electric Trailer Brakes # AKEBRK-7-SA along with # BRKH12 for installation. What kind of wheels do you have? Assuming you want a 6 on 5-1/2 bolt pattern you can use the Easy Grease Trailer Hub and Drum Assembly # AKHD-655-6-EZ-K. If you want an 8 on 6-1/2 bolt pattern you need the # AKHD-865-7-2-EZ-K...

These are self-adjusting brakes so they do not require periodic manual adjustment like standard brakes. To replace the original brake mounting bolts, nuts and lockwashers, you can use # BRKH12.

    So you'd have to change out everything, including the brake mounting flange, as the 6-bolt is simply not used anymore. There isn't a direct replacement from Dexter, so you'd need a 5-bolt brake mounting flange welded on (assuming you have a 3" diameter axle, which you should though you'll want to verify), the brakes, and a new hub and drum.

    I'll start off by saying that wheels and tires do not come with hubs, and what hubs you'll be able to use depend on the spindles on the axles, and whether or not you'll want brakes on the trailer or not. If you're going to be using the Timbren # TASR35HDS07, you'll need hubs that have # 25580 inner bearing and # 15123 outer bearings, like the # AKHD-655-6-EZ-K for a hub and drum assembly or # AKIHUB-655-6-EZ-K for idler hubs.
