Video Transcript for Redline Brake Assembly Mounting Hardware Installation

Hey everybody, Ryan here at etrailer. Today we're gonna be checking out the Redline mounting hardware for brake assemblies. One thing that you always seem to forget at least I do whenever you're doing trailer repair or trailer upgrades for that matter is the small things, right Like the nuts and bolts and small connectors and clamps and things of that nature. And a lot of times, you know when you're making those improvements you know you can break the bolts and break hardware and stuff too. And that's where a replacement bolt kit is gonna come into play. You know, so these are gonna allow you to mount up your drum assemblies or even your disc brake assembly brackets to the flange on your axle.

So these are gonna be seven sixteenths in diameter and these are designed to work with those seven and 10 inch assemblies. They might work with others too if that's what size hole you have in your flange air and pretty straightforward, you know what I mean It's just one of those things like today we're actually adding disc brakes to our trailer, right And so there was no existing hardware. It's like we took a drum brake assembly off and we're able to reuse those bolts. So we get in here and go, well, we forgot about it. So we got the kit and makes it a little bit easier even if you had an existing drum brake set up on here.

A lot of times, like I said it's just always, it never fails, you know especially if your trailer's super old and beat up it's almost better just to get new nuts and bolts. That way you're not fighting with it cause you know you know that's how it'll go. You'll try to save them and then something will happen and then having to take a trip to the store whatever the case may be. But pretty straightforward, you know, you got your bolt you're matching split lock washer and your hex nut there. And so these come in a few different, a few different varieties.

You know, there's a package for just one side of the axle so you get total of four or there's a whole pack that's for the whole axle or both sides of the axle. So you be able to do each side and you can buy 'em individually if you need to or buy multiples if you're doing a tandem axle trailer or something like that. So regardless on your current setup or what you need there's gonna be a solution for you. Once your bolts are all put in place though you wanna make sure to come back and properly torque 'em down using a torque wrench. And that'll finish up our look at of the Redline mounting hardware for our brake assemblies..

Mounting Bolts and Hardware for 10" Brake Assemblies - BRKH10A

Average Customer Rating:  4.6 out of 5 stars   (81 Customer Reviews)

Use this hardware kit to mount (2) 10" brake assemblies on your trailer. Includes mounting bolts, nuts, and lockwashers.


The hardware I received was a mixture of 1/2 inch bolts and 7/16 washers and nuts. I figured the 1/2 inch size was the way to go since the brackets were drilled for 1/2 inch. A trip to the hardware store and an hour of my time took care of the washer and nut problem. So now I have 8 7/16 lock washers and 8 7/16 fine thread nuts that I have no use for.

I soon realized that the mounting brackets on my new axles were pre-drilled for 7/16 hardware. So I drilled the brackets out to 1/2 inch to accept the bolts. Then,upon mounting of the supplied caliper brackets, I found that there was insufficient clearance for some of the washers/nuts to fit onto the bolts, so I had to go to undersized hardware. What a cluster!!


I definitely recommend a trailer for all parts regarding your marine boat trailer.


Didn’t put in lock washers with nuts and bolts.


Boat trailer brakes arrived on schedule and were in excellent condition. They fit perfectly and appeared to be of excellent quality. Very happy with the service and quality of the product.


As described. Being pre assembled made installation easy.



Easy to install. They are working fine.


great service and great products and great advice


only needed the nuts

Sometimes having the extra hardware on hand will work out in the long run. We do have the mounting nuts separately as part # 6-17.


The plating seemed to be top quality and the nut to bolt fitment was superb. The best thing is, they came right to my door. I didn't have to go to the hardware store to dig through the bin of nuts and bolts and possibly break a nail. Very convenient and safe.



The products were great and worked exactly as specified.


Regular every day nuts bolts and washers. Packaged right and delivered timely. That being said, the application I purchased them for was not a 100% fit. The electric brake backing plates came with the bolts already pressed in. The bolts in this kit are hex head and I don't think they would press in and clearance could be an issue. I have not done my install yet so can't say for sure. I will use the lock washers and the nuts.


Ordered these self adjusting Brakes to replace the manually adjusted front pair for a trial. The brakes were easy to install, and have worked well. I will buy another set to replace the rear set. Conclusion a nice easy upgrade anyone can accomplish. I would recommend this product.


It was easy to select the trailer brake kit. The dimensions were right there so I could measure what I needed and order. Glad I read the reviews that said to purchase replacement hardware too. Quick delivery And I am all set


My old hardware for my brackets was completely rusted and bolts were rounded off and hard to be cut/drilled out. This was a perfect replacement


Don't know if I will need these yet, but I was glad to be able to get these at the same time I purchased the brake assembly.


Was very pleased with the purchase. The only small negative on my order was the adjustment assembly was missing on the right side brake assembly. The good point was a new one was shipped and received within 2 days. To me that was very impressive. Good job by customer service department.


All bolts, nuts and lock washers were present and accounted for. Grade five, nothing special but handy to have them delivered with the brake package and save a trip to town.


I only needed the nuts and lock washers, but they worked perfectly.


This was just part of my disc brake order. My whole order came in 2 days. Paid extra for 3 day delivery. No problems with my order. As always etrailer is A1.


Product arrived in excellent condition and clean. I was eligible for free shipping. Order was placed on sunday afternoon and received north of NY state on next friday. I would definitely consider buying from etrailer again.


Brake assy. for my boat trailer fit perfect.Fast delivery and great customer service.


Very pleased with the knowledge,assistance and guidance Kevin provided me with my purchase. Items shipped the same day and arrived in 6 days. Trailer break items were all the proper size and fitted perfectly. Job well done, thanks a million.


What can you say about nuts and bolts except that they fit and arrived on time. Thank you.


Be sure to order these to mount new electric or disc back plates. Four needed per wheel, 8 per axle.


Make installation much easier


Ordered complete set of brakes and other items for my trailer and got them today.
Very fast delivery. I wish all companies were this good in dealing with customers.
I rate them excellent.


the bolts corroded in no time, had to go to home depot to get new ones. cheap China stuff

  • Is TruRyde Electric Trailer Brake Kit For 3,500 lb Axles Correct For 2017 Winnebago Minnie 2500RL
    You do have the correct electric brakes for your 2017 Winnebago Minnie 2500RL with the TruRyde Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand - 3,500 lbs # TRU36FR. The magnet would be an issue if you see their windings beginning to show through the friction surface of the magnet, but in general if the brakes are still functioning then the magnet is fine. The # TRU36FR come with magnets so you wouldn't have to replace those separately; the only other thing you...

  • Hydraulic Drum Brakes for 3,750 lb Axle For 15 Inch Wheels
    The Titan Hydraulic Brake Kit - Free Backing # T4071600-500 will fit so long as your drum is 10" diameter x 2-1/4" wide, and you have a 4-bolt brake mounting flange. This is a pretty common set up so it will likely fit but you'll want to make sure, and these brakes will also work with either a 14 inch or 15 inch wheel like you have. These brakes are for a 3,750 lb axle and would only require Mounting Hardware # BRKH10A. I have added a link to a video review for you to check out as well...

  • How to Determine if Dexter Brakes T1878800-700 Fit
    I can tell you how to determine if the Dexter Hydraulic Brake Kit # T1878800-700 fit your trailer, but we have no way of knowing fits for any one trailer. You'll need to measure the inside of your drum and it needs to be 10" diameter and at least 2-1/4" wide; you need to have a brake flange with four mounting holes, and your wheels need to be 14" or 15". If you meet those requirements you can use the # T1878800-700; you'll also need Mounting Hardware # BRKH10A.

  • What Size Brake Mounting Flange Bolt Do I Need for a Car Hauler Trailer
    The correct size nuts for the brake mounting flange bolts you have on your trailer is going to depend on which bolts you have. There is not really a standard thread pitch for braking assemblies so it will be best to replace the nuts and bolts with part # BRKH10A which contain 7/16"-20 x 1-1/4" bolts/nuts and lock washers. There is also a tool that you can find at most local hardware stores that will tell you the diameter and thread pitch of your bolt.

  • Determining Which Brakes Fit 10" x 2-1/2" Drums On Boat Trailer
    Based on the information you provided either the Titan Hydraulic Brake Kit - Free Backing - 10" - Left and Right Hand Assemblies - 3,750 lbs # T4071600-500 or # T4423500-400 will fit your drums. The only difference between these two brakes is the # T4071600-500 are made of standard metal where the # T4423500-400 have a Galphorite coating giving it superior corrosion resistance. Since you are putting these brakes on a boat trailer I recommend the # T4423500-400 as they will be less likely...

    The correct braking assemblies for your 2016 Crossroads Sunset Trail Super Lite 15 250RB are going to be dependent on the size of your drums. Since your trailer has a GVWR of 7582 and tandem axles it more than likely uses 10" brake assemblies which are the Dexter # 23-468-469 or the etrailer # AKEBRK-35-SA. You can confirm this by measuring the diameter and depth of your drums following the included diagram. Neither kit comes with new mounting hardware so if your current hardware is in...

    The axle part numbers are generally placed on a sticker located at the center point of the axle shaft. The part # 8-247 stamped into the hubs tell me that you have a 3,500 lb axle. To replace the drum brakes on your 3,500 lb Dexter axle you will have a few options. The two options entail the use of self-adjusting or manual brakes. The self-adjusting brakes will move the adjuster screw outward as the pads wear down to ensure optimal wearing and performance of the trailer's brakes, whereas...

    I recommend using the Hydraulic Brake Kit - Uni-Servo - Free Backing - Dacromet - 10" - Left/Right Hand - 3,500 lbs # AKFBBRK-35-D, which will work with your current setup and are perfect because the Dacromet plating is designed to withstand exposure to water; so they're ideal for boat trailers.

The complete assembly is often less expensive than replacing the individual components. If you want just the components you mentioned, I recommend the 10" X 2-1/4" Hydraulic Brake Shoe/Lining (One Wheel) # BP04-120 and the Wheel Cylinder - 10" and 12" Single Servo RH # BP17-020 in addition to the left hand # BP17-030.
