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.

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. 51742


Comments

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.

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. 394518

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. 633997

  • 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. For your brake assemblies, I recommend the Electric Trailer Brake Kit - Self-Adjusting # AKEBRK-7-SA along with mounting hardware # BRKH12. 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...

  • Recommended Brake Mounting Flange To Welded On Brake Assemblies
  • Thanks for the picture. Those assemblies look pretty rough and definitely need to be completely replaced, but are unlike anything I've seen. It looks like it was a custom job. I recommend removing them completely and having a professional welder add the Brake Mounting Flange for 3" Round Axle # 4-44-1 to your axle. This will need to be welded in place but will give you up to date braking assembly options that can be adjusted, and parts replaced as needed. I recommend the Electric Trailer...

  • Replacement 12 inch Brake Assemblies for Hadco Trailer Axles
  • We 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...

  • Recommended Electric Trailer Brake Assembly for 6K Axles
  • The brake flange for 3 inch axle tubes is the Redline Brake Mounting Flange for 3" Round Axle # 4-44-1 which has a 5 on 3-7/8 inch bolt pattern. This is the industry standard and I don't have anything like what your mentioned with 10 holes and 8-1/4 inches apart. For the brake assemblies you mentioned which are compatible with the 5 bolt flange listed above, I recommend the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies - 7K # 23-464-465. For...

  • How to Determine What Hubs Are Needed for Escort Boat Trailer
  • Yes, you can replace your hydraulic brakes with electric brakes. You will need to know your axle capacity and have the appropriate brake mounting flange. For example, with a 12" x 2" drum there is the Electric Trailer Brake Kit # AKEBRK-7-SA, which is for axles with a 5,200 lb - 7,000 lb capacity and will work with a 5-bolt mounting flange such as # 4-44-1. You will also need a brake controller, breakaway kit and wiring, some of which is vehicle-specific. Second, in order to find the...

The brake kit and hub and drum assembly that my contact had on file was for a 5,200 lbs axle.

  • Bolt Pattern of 5 Bolt Brake Mounting Flange for Trailer Brakes
  • The bolt pattern for a 5 bolt brake mounting flange, like # 4-44-1 is 5 on 3-7/8 inches. What that means is it measures 3-7/8 inches from one corner to its diagonal counterpart. From hole to hole across the bottom is 3 inches and between the others is about 2-1/8 inches. I've made a diagram that may help.

  • Will 5 Hole Brake Backing Plate fit Mobile Home Axle
  • Our 5 bolt mounting flange, # 4-44-1, will fit 3" round axles and fits with 12" brake assemblies like # 23-105 for the left side and # 23-106 for the right side. We recommend having brake mounting flanges installed by trailer building professionals, that have a jig to hold the brake mounting flange square and concentric to the spindle, for proper braking performance.

  • How to Determine the Capacity of 2 Inch Square Axle
  • Square axles can be tough to determine capacity since the same spindle can typically fit a range of axle capacities. With this being said the absolute best way to determine the capacity of your axle is to locate a plate/sticker on the axle itself or on the trailer. If this is not available we can take a few steps to try and narrow it down for you. 1) A 2 inch square axle using a 5 on 3-7/8 inch brake mounting flange is typical of 5,200, 6,000, and 7,000 lb axles. If you can provide the...

The bolts these are designed to fit to are actually studs that are attached to the mounting flange of your current spindle like the part # 4-44-1. For nuts and washers that fit that you'd want the part # 38LW and # 38N.

  • Can Dexter Electric Drum Trailer Brakes Replace AL-KO Trailer Brakes
  • We actually have 12 x 2 inch electric drum brake assemblies that are replacements for the AL-KO brake assemblies. Take a look at Hayes/AL-KO 12 x 2 Electric Brake Assembly, # 185150. This is the right hand assembly. The left hand assembly is # 185100. The Nev-R-Adjust Electric Brake Assembly, # 23-459, will fit provided that the bolt hole pattern on the brake mounting flange matches your existing set up. It should have a 5 on 3-7/8 inch bolt pattern, like flange # 4-44-1, to work.

You need to know that the brake assembly is compatible with the brake mounting flange and with the drum's diameter and depth. I added a photo showing how to measure a hub/drum for you, Typically 6,000 lb Dexter axles have a 5 bolt brake flange, like part # 4-44-1, and utilize 12 x 2 inch brake assemblies, like part # 23-106. The correct brake shoes for these assemblies are part # AKBRKR-S-12. If you...

  • Is a Gap Between a Trailer Brake Backing Plate and Drum Normal
  • The slight gap you see is normal. The drum is not supposed to make contact with the brake mounting plate. There are some instances when mixing brands of brakes, hubs, and axles, that won't line up properly but in this case it is normal. I did also run it by another set of eyes just to make sure and we both came to the same conclusion.

  • This is quite the dilemma that took me a few readings to understand completely. There's no easy answer though since as you realized all of the 10 inch brake assemblies require a 4 bolt mounting flange (you have a 5 bolt flange), and none of the 12 hub/drums we offer have a 5 on 5 inch bolt pattern like what your trailer wheels need. I believe your best possible solution would be to remove the brake mounting flanges you have on your trailer and install new ones that will match up to the...

  • How to Find Wheel Bolt Pattern to Find the Correct Replacement Trailer Brakes
  • There are a couple of methods you can use to determine bolt pattern of the wheels themselves. First, you can use the number of lugs and the bolt circle. For an even number of lugs, measure the center to center distance of 2 lugs directly across from each other. If you had 6 lugs and the distance measured is 5 inches, you have a 6 on 5 bolt pattern. For an odd number of lugs, it is a little more difficult. Measure from the center of 1 lug directly across to the center point between 2...

If this is the case then the bottom mounting holes are 3" apart on center with the other holes being 2-1/8" apart on center just like you mentioned. If you are needing new mounting hardware then the kit # BRKH12 is what you are needing for these 12" brakes. Attached is an installation video of this kit for you to reference.

  • How Should a Trailer Brake Mounting Flange be Welded to a Trailer
  • To weld on a brake mounting flange such as # 4-44-1 it requires a special jig and someone with experience in welding on brake mounting flanges. They have to be perfectly square and concentric and if off just a little bit it can lead to all kinds of problems with trailer ride, stability, tire, and suspension wear. You would need to find someone locally who has the proper equipment and has done this type of installation before. A place that sells trailers and RVs and has a service center...

  • Parts for Lugged Hubs on a Mobile Home Axle with 15123 inner and 25880 Outer Bearings
  • It 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...

  • The 8-133 hub is a mobile home axle hub. Typically these hubs are very hard to find replacement parts for since they are designed for one time use. I recommend replacing the entire axle and its setup, it is likely that the weight capacity is between 5,200-7,000lbs, since they are 12 inch brakes. We offer an 5,200 axle-less system by Timbren # ASR5200S04 that uses the same inner and outer bearing numbers that the 8-133 axle did according to Dexter. If you wanted to try to replace...

  • Dimensions for a Brake Mounting Flange for a 3 Round Axle
  • The measurements of the Brake Mounting Flange for a 3 inch Round Axle, part # 4-44-1, are correct, in that the inner diameter of the flange is 2-3/4 inches. This is because the flange will be mounted to the spindle, not the axle. You will need to check the Outside Diameter of your spindle, as this will mount on the spindle.

  • Installation of Redline Brake Mounting Flange # 4-44-1
  • On 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...

If this is the case you could use 12 Inch Nev-R-Adjust Electric Brake Assembly for 6,000 LB Axle, # 23-458 for left hand side and # 23-459 for right hand.
