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.

I ended up not needing these and will return. etrailer's customer service was excellent !

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

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: Corey 03/12/2018 One Year Later

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: Douglas 04/21/2021

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.

by: Scott 07/28/2020

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

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).

by: Mitch 07/23/2018 One Year Later

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.

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: John 01/17/2022

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: David P. 07/25/2017

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: Jason 02/12/2024

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: Arizona Slim 03/27/2017

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.

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

Replacing Warner 12 Inch Electric Brakes & 6 Bolt Mounting Flange
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. The flange and brakes are the following: - Brake Mounting Flange for 3" Round Axle # 4-44-1 - Dexter Electric Trailer Brake Kit - 12" - 6,000 lbs...

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...

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...

Recommended Self-Adjusting Brakes for a 5,200 lbs Axle
Hey Todd, welcome back! The most affordable set of self-adjusting brake assemblies I have for a 5,200 lbs Lippert Axle are the etrailer Electric Trailer Brakes item # AKEBRK-7-SA. This is a set of left and right brake assemblies that fit a 5-bolt brake mounting flange. These will save you quite a bit of money over going with the comparable Dexter item # 23-458-459. Most brake assemblies for 5,200 lbs to 7,000 lbs axles are the same size and have the same 5-bolt brake flange pattern. You...

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?

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

Replacement Bearings for 7K Axle on 2017 Dutchmen Voltage 5W Toy Hauler
In most cases, it's going to be more cost effective to replace all of the components than it is to simply swap out the axle. You could go with a complete axle like the Dexter Trailer Axle w/ Electric Brakes - E-Z Lube - 8 on 6-1/2 Bolt Pattern - 94" - 7,000 lbs # 8327864-EB if your current axle is 94" from hub face to hub face. In reality, it's probably going to be most cost effective to replace your hubs, drums and brakes though. If you can confirm the bolt pattern on your current wheels,...

Hey James! Yes, the etrailer Electric Trailer Brakes # AKEBRK-6 will work well as a replacement for your current Dexter # 23-105-106 brakes. They have the same capacity, fit a 5-bolt brake flange, and will work with your existing hub and drum assembly. If you need replacement mounting hardware # BRKH12 is also available. Timken seals are going to be a higher quality compared to our generic seals and Dexter. Are you saying you were adding grease with the wheel off the ground and spinning...

Recommended Tire Size Compatible with Timbren HD 3500-lbs Axle-less Suspension System
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. If you're going with the hub and drum so you can add brakes,...

Hardware for etrailer Electric Trailer Brakes - 12" - Left/Right Hand Assemblies
Hey Brian, welcome back! Brake mounting hardware is not included with the etrailer Electric Trailer Brakes # AKEBRK-6. What you need is the Mounting Bolts and Hardware for 12" Brake Assemblies # BRKH12. This is enough for a pair of brakes, so you will need a quantity of two if you're ordering two sets of brakes. Also just a heads up, these are manual adjust brakes. If you want self-adjusting I recommend picking up the TruRyde Electric Trailer Brakes # TRU96FR instead. Do you still have...

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...

Availability Of Hub/Drum Kit With Brakes And Hardware Similar To Part BPH1206EPR
Hello Brian, we do offer some parts that will work for your application and will be very similar to the BPH1206EPR kit that you mentioned. Like you said, the 12 x 2-1/2 drums are pretty uncommon, so I would have to recommend going instead with the standard 12 x 2 drums which will be readily available. Take a look at the parts below. Aside from the drum depth specs will be identical. Dexter Trailer Hub and Drum Assembly - 5,200-lb and 6,000-lb Axles - 6 on 5-1/2 - Pre Greased # 8-201-9UC3-EZ Dexter...

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...

Recommended Hydraulic Brake Assemblies, Actuator, And Brake Lines For Dual Axle RV
For your conversion to hydraulic brakes on your 7,000 lb dual axle RV, I recommend the Hydraulic Brake Kit - Uni-Servo - Free Backing - 12" - Left/Right Hand Assemblies - 5.5K to 7K # AKFBBRK-7. These assemblies are side specific and are labeled for you. These will work with your current hub and drum assemblies. For installation and adjustment, you will want the Brake Adjustment Spoon for Drum Brakes # W80630. If you need the mounting bolts for these assemblies, I recommend # BRKH12. If...

How to be Sure Brake Assemblies Will Work on 7,000 lb Axles
Knowing the weight capacity of your axles is a good first step in determining if the Electric Trailer Brake Kit - Self-Adjusting # AKEBRK-7-SA will fit your Logan 7903 LQ. You will also need to know the mounting flange bolt pattern on your axle, your wheel size and the dimensions of your drum. These brake assemblies have a 5-bolt mounting flange pattern, fit 14-1/2", 15", 16", and 16-1/2" wheels and are 12" diameter x 2" wide. You would need mounting hardware # BRKH12 to install these....

Availability Of Stainless-Steel Brake Caliper Mounting Bolts
Hey Jim, thanks for reaching out. Unfortunately, no, we do not. All of the caliper bracket mounting bolts we offer are zinc coated like part # BRKH12S. What they are is 1-1/4" long 3/8" - 24 grade 5 bolts so if you can find a stainless version of that locally that would work just fine.

Replacement Electric Brakes for Dexter PR-FF SEC-FF 5.2KPR-GGSEC-GG 12X2XQ 36-89
Based on the photo and information you provided, I can tell you have 12 x 2 inch Dexter brake assemblies for 5.2K axles, for which the Electric Trailer Brake Kit # AKEBRK-7-SA will be an excellent replacement. 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.

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.

Replacement Brake Assemblies and Hubs for 1960 Airstream Trailer
It sounds like your assemblies are not the typical assemblies and will need to be replaced.

If you don't have the brake flange compatible, you can use the Brake Mounting Flange for 3" Round Axle # 4-44-1 which needs to be precisely welded in place. Then for your drum brake assemblies to match, I need some more information. I will need either the...

Replacement Brake Assemblies for AL-KO T-44 Axles
I have a solution for you, but the AL-KO T-44 axle has been discontinued since Dexter bought them out and there are no longer parts available for them, so you would need to completely replace the axles in order to replace the brakes. To choose the correct replacement axle you will need to know the hub face to hub face measurement and spring seat center to spring seat center measurements of your current axle; you'll also want to try to match your existing bolt pattern with the hubs in...

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.

Hydraulic Drum Brake Actuator and Brakes for Dexter 8-201 Hub and Drum on Boat Trailer
I have added a link to a help article on everything you need to replace (or add) hydraulic drum brakes, but let's start with the actuator.

For example, the Titan Zinc-Plated Brake Actuator - Drum Brakes # T4079200 has an 8,000 lb capacity, couples...
