Video Transcript for Redline Trailer Brakes 4-44-1 Review
Today we're going to be taking a look at a brake mounting flange for a 3" round axle. The brake mounting flange gets welded to the spindle at the end of the axle to provide secure mounting plates for brake assemblies. This flange works with a 12" diameter brake assembly. It's going to come with the bolts already pressed in you can see that it's a five-bolt mount. The bolt pattern is 5 on 3-7/8", so that means that we have five bolts, and then from the center of this one to the center of this one, as well as this one to this one, it's going to measure 3-7/8". Center on center between these two is going to be 3". This is designed to fit 3" diameter axles. The bolt diameter is 3/8", so this will work with 4.400 lb, 6,000 lb regular duty, 6,000 lb heavy duty, 7,000 lb and 7,200 lb axles.
The diameter of the pilot hole, so the hole right here at the center, that's going to measure 2-3/4" in diameter. The flange itself is made from a durable steel construction, it's going to measure 1/4" thick. Taking a look at the overall measurements. Going side to side, it's going to measure about 4-1/2". Going this direction, that's going to give us a measurement of about 4-3/16". That's going to do it for today's look at the brake mounting flange for a 3" round axle.

Brake Mounting Flange for 3" Round Axle - 4-44-1
Average Customer Rating: 4.3 out of 5 stars (32 Customer Reviews)

Upon inspection if receiving my recent order I noticed that the packaging was sub par at best. The box didn't seem to be visually damaged externally, however the inside told a different story I ordered 2 sets of electronic brakes. Some hardware and a tub of packing grease. If you see the pictures attached, everything was thrown into a massive box without proper packing material and some of the items show signs of shipping damage. Some brakes were out of alignment and the grease canister was smashed almost to the point or rupture. For such a big company I would expect a little more care to be given to the several hundred dollars worth of parts in my order.

I had to machine the parts so they fit my application of older mobile home axles.

This is an exelent flange if you want to convert an axel that is not allredy a breaking axel it worked great for me
by: Stephen10/05/2020
It is a flange for a 3” round axle. It is to be welded onto the axle. Unfortunately, the inside diameter is ONLY 2.75 “. It will not fit directly onto the axle unless you do some serious grinding. It is possible that I do not know how it should be attached but....

Thank you for your review. The brake flange is designed to fit onto the spindle just behind the seals not on the 3 axle.
by: Jason D.06/15/2017
High quality and well made. Made to fit the spindle of a 3" Axle. It fit, but the brakes would have been so far out on the axle that the hub would not even bolt on. Glad I checked before welding. Further investigation found that I have a shorter than average spindle length.
THESE MOUNTING FLANGES WOULD NOT WORK FOR ME AND WERE RETURNED!
Mobile home axles usually come in two "basic" sizes. The "smaller" size spindle, with the 1.9" grease seal and or 1-3/8" inner bearing (the larger spindle "usually" has a 2.25" grease seal and 1-3/4" inner bearing)
If you have the Larger axle, with the 1-3/4" inner bearing and larger grease seal then this mounting flange should work.
I had the 1.9" Grease Seal and therefore a shorter spindle length, so I had to weld the brake backing plate directly to the 3" axle tube.
THESE MOUNTING FLANGES WOULD NOT WORK FOR ME AND WERE RETURNED!
I put the brake assembly on the axle, reinstalled hub and bearings then tightened down. Next, put the brake assembly in the hub and adjust brakes tight to the drum while keeping both concentric. When both are tight together make sure brake adjusting holes are at bottom towards the ground and weld brake backing plate to the axle.
by: Jonathan04/22/2019
I've been restoring a 1979 Hudson trailer on which the brake backing plates were welded right to the axles. That makes rebuilding the brake system impossible unless you cut off the exiting material and install these flanges. This is pretty much the only way to do it.
These flanges are stout -- 3/16" plate, laser cut for precision. If you install them properly you won't have to worry about the flanges failing.
These brake flanges have to be absolutely square and concentric on the axle, and the0y need to be at the proper depth relative to the spindle. I think the best way to get it right is to dry-fit everything and then jig the flanges and the brake backing plates in position with magnets or a similar means. When everything is in alignment, tack weld the flanges to the axles, then take all the other parts off and finish your welds.

I am putting on electric brakes on Mobile home axles and needed a way to mount the new backing plates. This seems to be the way to get it done. I had great help from Greg S on how to go about it.
by: Kent S04/11/2020
Bolts like up perfectly. The center hole needs to be bored out to be used on mobile home axles.
They can also be a challenge to weld square to the tube.
by: James08/22/2021
Works perfectly on my old trailer which had welded on backing plates. I scanned it and was able to build three more with the plasma cutter.

This produce was delivered in record time. It is exactly what was needed to complete my project and get me back on the road with little to no down time. Thanks to all the team members at etrailer for their help.
by: Willy R08/15/2012
Careful if you get this product. I specified for a 3" tube. What I got was ID 2.754". Thankfully I have a lathe and was able to bore it out to size.
Would be nice if the parts room checked the sizes before they send instead of grabbing what was on the shelf.

The part you received is correct. The flange is for use on 3 inch axles, but it does not mount to the axle.The spindles on 3 inch axles measure 2.75 on the shoulder where the flange should be welded. It should be mounted to the shoulder of the spindle right next to where the spindle is welded to the axle.

Did the job, as it was pictured and described. Trailer is rolling again.

- Can Brake Mounting Flanges be Added to Trailer AxlesYou can add brake mounting flanges to axles based which you'd need to know the diameter of your axle to pick out the correct one. Part # 4-44-1 is for a 3 inch axle, part # 4-35 2-3/8 inch axles, and part # 4-50 is for 3-1/2 inch axles.
view full answer... - Recommended Hubs and Brakes for Building Trailer With 5,200 Pound AxleThere are a few things going on here that I will attempt to address regarding your axles. The first being that you do not have a brake flange like the # 4-44-1 on these axles. In order to use any type of brakes they will need a brake flange. Based on the condition of the axles I wouldn't recommend welding a brake flange on but if you do you will need to have that done by someone with the right tools and skills to make sure it is correctly aligned. As for the capacity, it does sound right...

- Installation of Redline Brake Mounting Flange # 4-44-1On the Redline Brake Mounting Flange, part # 4-44-1, the five bolts are press fit into the flange. To be removed they would have to be pressed out with a hydraulic press. Once they are pressed out the bolts are not to be used again. So you would not want to remove the bolts from the flange. The flange needs to be welded on concentric and square. Square meaning the flange must be a true 90 degrees from the spindle and concentric meaning the gap around the spindle must be the same 360 degrees...
view full answer... - Parts for Lugged Hubs on a Mobile Home Axle with 15123 inner and 25880 Outer BearingsIt sounds like you have a spindle that uses the Inner Trailer Hub Bearing, item # 25580, that has a 1.750 inch inner diameter. The outer # 15123 bearing has a 1.250 inch inner diameter. I would check the seal surface on the spindle to be sure that it matches the # RG06-070 seal inner diameter of 2.250 inches. Many times mobile home axles use non- standard parts so careful measurement of all of the parts is required. If all of these dimensions match, then you will need to determine whether...
view full answer... - Recommended 12 X 2 Electric Trailer Brakes to Replace Hadco AssembliesWe have a large selection of 12 x 2 electric brake assemblies available, which I have linked for you to look through. I recommend looking at the etrailer.com Electric Trailer Brake Kit - Self-Adjusting # AKEBRK-7-SA. These 12 inch assemblies are designed for 5,200 to 7,000 pound axles and feature a 5 bolt mounting flange bolt pattern. They are also self-adjusting so they will not require periodic manual adjustments like standard brakes. I have included a short video demonstration on this...
view full answer... - Will Brake Assemblies AKEBRK-6L and # 23-106 Both Attach to Flange 4-44-1Both brake assemblies you mentioned will fit the mounting flange part # 4-44-1 that you referenced. Both assemblies are essentially the same thing made by two different companies. The part # AKEBRK-6L and # 23-106 are both 12 inch by 2 inch assemblies that mount to 5 bolt mounting flanges that are manual adjust.
view full answer... - Replacement Brake Mounting Flange and Assemblies for 2003 Wehaul Snowmobile TrailerMost likely what you need for a brake flange is the part # 4-35 which has the standard 4 on 2-7/8 inch bolt pattern measured on center but you should measure yours again to be sure. This is a very common bolt pattern whereas 3 inches is not an option that we carry. This also fits the standard 3,500 l trailer axle diameter of 2-3/8 inches. So based on that the assembly set that you'd need is the part # AKEBRK-35-SA. This is a self adjusting set of brakes that fits a 10 inch hub/drum.

A new hub/drum has to use the same bearings and seals in order to fit on the current spindles. Please refer to the linked photo diagram that shows how bearing and seal numbers usually appear on these parts. Pull one hub so you can remove the bearings and seal and try to find the part numbers. Most of our 8-on-6-1/2 hub/drums...

- Can Electric Drum Brakes be Added to a 1993 Jayco 1206 TrailerThere are a few things to consider when adding electric brakes to a trailer. The first thing to check is if the axle has brake mounting flanges to attach the brake assemblies to. Flanges are welded to the axles and look like # 4-44-1. If you do not see brake mounting flanges they have to be welded on. Welding on brake mounting flanges is a precision job that requires a special jig and someone with experience performing the installation. If the trailer does have flanges then note the...
view full answer... - Replacement 5 Lug Hubs/Drums and 12" Brakes for Mobile Home AxleIt sounds like you're looking for the Dexter Trailer Hub and Drum Assembly part # 8-174-5UC3. In regards to the braking assemblies, I don't think we have anything that matches up with what you said you had, only option we could offer is a new brake flange like the Brake Mounting Flange for 3" Round Axle part # 4-44-1 which requires welding and then the Dexter Electric Trailer Brake Kit part # 23-180-181. The other option you have would be to get some new custom axles. Unfortunately, parts...
view full answer... - What is the Mounting Hole Pattern for Dexter 6K Electric Trailer Brake AssembliesThe mounting holes are actually closer to 2-1/8 inches for the closest ones and 3 inches for the bottom 2 holes on brake assembly # 23-105 and # 23-106. I have included a picture showing the measurements. It is very close and you could call it 2 inches but the brakes fit a standard 5-bolt mounting flange such as # 4-44-1.

- Which Brake Mounting Flange for 3 inch Diameter Axle BeamGiven your 3 inch diameter axle beam, you have a 5200, 6000 or 7000 lb rated axle, which is compatible with a 12x2 inch brake assembly. A 12x2 brake assembly would use a standard 5 bolt brake mounting flange. For a 3 inch diameter axle beam, I'd recommend using # 4-44-1 for 3 inch axles. You'll want to have a professional welder who's experienced in trailer work install these. If they aren't installed so they're perfectly straight and concentric, you'll have no end of trouble.
view full answer... - Brake Flange To Fit 12" X 2" Brake Assemblies On an Old Utility Trailer AxleChris, I am unaware of any 12x2 brake assemblies which have a 7" bolt pattern spread. We do have the Brake Flange # 4-44-1 you can have welded onto your axle so you can use the etrailer Electric Trailer Brakes # AKEBRK-7-SA.
view full answer... - Axle Recommendation For Use With Kodiak Disc Brake Kit, part # K2HR526DSThe Kodiak Disc Brake Kit, part # K2HR526DS, will fit on a 5200 lb to 6000 lb axle with 5-bolt brake mounting flanges. This kit will require you to use 15 inch and larger wheels with a bolt pattern of 6 on 5-1/2 inches. The disc brake kit will work on a torsion axle if it has a 5-bolt brake mounting flange welded to the spindle. The brake mounting flange would be like the Redline Brake Mounting Flange, part # 4-44-1. This flange has a bolt pattern of 5 on 3/7/8 inches, which will accept...
view full answer... - Left and Right Hand Assemblies for 12 " Electric Trailer Brake Replacement I recommend the Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies item # AKEBRK-6. These are 12x2 inch drum brakes that are rated from 5,200 lbs to 7,000 lbs and will fit your 5 bolt pattern. The brake pads are made of durable friction material for improved braking and longevity and E-coated backing plates that resist rust. They fit 14-1/2" to 16-1/2" wheels. If you need hubs message me back with your lug nut bolt pattern and I would be glad to make a recommendation. I have...
view full answer... - Need Brake Flange For Adding Brakes to Homemade TrailerSince your hubs are for 5200-lb axles and you've confirmed that you do have a 3" diameter axle, you'll need the Redline 5 Bolt Flange # 4-44-1 . You should know, if you don't already, that brake flanges need to be welded perfectly concentric. For that reason we generally recommend that the work be done by an experienced trailer shop that has the required jig. To add brakes to your axles you'll need a couple additional parts- brakes and a hub and drum assembly. For brakes I recommend the...

According to my contact at Lippert these axles were special ordered that way, but there are no longer any replacement brakes in that orientation. Minus replacing the axles the best option would be to have the factory brake mounting flanges removed and have an axle shop weld on new flanges # 4-44-1 in the standard orientation. This will allow you to use the # AKEBRK-7-SA you were...

- Electric Trailer Brakes are too Weak to Stop Boat Trailer with Three 5,200 Pound AxlesIt looks like you purchased Electric Trailer Brake Kit # AKEBRK-7-SA. These brakes are designed for 5,200 pound to 7,000 pound trailer axles. This means that they use the bigger, stronger magnet than typical 5,200 pound assemblies. They have to in order to work with axles up to 7,000 pounds. Switching to the Dexter magnet would be a downgrade. Since these are being used on a boat trailer I recommend checking for signs of corrosion that could impede the movement of the internal parts. If...

To recommend the correct hub drum for your application, I would need to know your current hub bolt pattern, as well as the bearings it uses. In order to determine your hub drum bolt pattern, you would need to measure center...

Please note that if they planned on only using the trailer once they might have used a mobile home axle. If that is the case...

- Parts to Convert From Electric Brakes to Electric Over Hydraulic Disc Brakes on 6,000 lb AxleThank you for all that detailed information, it is exactly what we need to get you set up with brakes so you can keep your family safe like you mentioned! You initially said you wanted to switch over from drum to disc brakes, but in your question you referenced an electric over hydraulic actuator and brake controller, so it sounds like you want to switch to electric over hydraulic (EoH) disc brakes for the best braking possible. To get this set up, you will need a new hub and rotor for...

Also, I did want to mention a 2,000 lb axle is typically 1-3/4 inches in diameter, and for that the correct part is the Brake Mounting Flange for 1-3/4" Round Trailer Axles - 2K # 4-34. That is a 4-bolt mounting flange, though we do have brake mounting flanges for 3 inch round axles, which are typically 5,200 lb to 7,000 lb axles. These are 5-bolt mounting flanges and for that the correct part...

Welding on a new brake flange requires a specialized jig and excellent welding skills to ensure the flange is straight and concentric with the spindle. This is usually best left to a professional.
