Video Transcript for Redline Trailer Brakes 4-34 Review

Today we're going to be taking a look at a brake mounting flange for a 1 3/4 inch round trailer axle. This brake mounting flange gets welded to the end of the axle to provide a secure mounting place for a brake assembly. It does work with seven inch brake assemblies. Again it's designed for 1 3/4 inch round axles, or 2,000 pound axle, or typical 2,000 pound axle. The center hole is going to give us a diameter of 1.64 inches. The hole spacing, the distance that we have center on center between each of those holes is going to be the same at 2 7/8 of an inch, center on center.

Overall measurement is a square design. It's going to measure 3 3/4 of an inch by 3 3/4. As you can see, it's a four molt hole design. That's going to do it for today's look at the brake mounting flange for a 1 3/4 inch round trailer axles.

I had to replace the old hydraulic disc brakes on my Tryton 20' snowmobile trailer and need to add new mounting plates for the new electric drum brakes. These worked great. Cut the old mounts off the spindle and welded these on. A whole lot easier than making from scratch!!!

  • A Professional Should Install Trailer Brake Mounting Flange # 4-34
    You are correct about needing to have a brake mounting flange like # 4-34 welded on correctly. Because it needs to be just right it should be installed by a qualified professional in a shop that works on trailers. We do not have specific instructions for installation, but a pro will know how to do it.

  • Why is Brake Mounting Flange for 1-3/4" Round Trailer Axles # 4-34 Center Hole Larger than 1-3/4"
    That is the correct hole size for brake mounting flange # 4-34. That would leave space for an approximate 1/8 inch weld all around the spindle. Because welding on brake flanges is a precision job it is recommended to have a professional welder with experience welding on flanges to perform the installation. A special jig needs to be used to ensure the flanges are perfectly straight/concentric or it could lead to tire wear and other issues that will negatively impact the performance of the...

  • Which Direction Does the Brake Flange 4-34 Face When Mounted?
    You will want to orientate the Brake Mounting Flange for 1-3/4" Round Trailer Axles - 2K item # 4-34 so the dimples face outward from your axles.

  • Brake Mounting Flange That Fits 2,000 lb Axle
    So we have brake mounting flanges, but they are all weld-on applications as opposed to bolt-on. 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...

  • How to Find the Correct Brake Mounting Flange
    Capacity is what will have the capacity as opposed to the spindle, and the correct brake mounting flange will depend on the diameter of your axle. Since you mentioned a 3,500 lbs I assume that is your axle's capacity and typically those have 2-3/8" diameters. For that there is the Brake Mounting Flange for 2-3/8" Round Axle # 4-35. We don't have any flanges for 2" axles, but the other possibility is the Brake Mounting Flange for 1-3/4" Round Trailer Axles # 4-34 which is the typical diameter...

  • Electric Trailer Brakes for 4-Bolt Flange 2-5/8" x 3-5/8" Apart
    I do have an option for you but none of our trailer brake assemblies are designed for this brake mounting flange pattern. Therefore, I recommend new flanges which will need welded to the axle; part # 4-34 for 1-3/4"axles, part # 4-35 for 2-3/8" axles, and part # DM52415 for 3" axles.

  • Brake Mounting Flange Recommendation for a 2k Rated Trailer Axle
    What you will want to do is purchase the part # 4-34 as this is a brake mounting flange designed for 2k axles. The brake mounting flange needs to be welded on perfectly square and concentric and if it is off just a little bit, this can lead to all kinds of problems with trailer ride, stability, tire, and suspension wear. We strongly recommend that brake flanges be welded on by a professional shop that routinely works on trailers and has the equipment required to weld the flange to the spindle.

  • Brake Mounting Flange Recommendation for Fitting a 1-3/4 inch Diameter Axle
    For a brake mounting flange that fits a 1-3/4 inch diameter axle the part # 4-34 is exactly that. As long as the rest of the axle looks fine and isn't rusting as well this would be exactly what you need. The brake mounting flange needs to be welded on perfectly square and concentric and if it is off just a little bit, this can lead to all kinds of problems with trailer ride, stability, tire, and suspension wear. We strongly recommend that brake flanges be welded on by a professional shop...

    The only 4 bolt mounting flange we offer that has a 1-3/4 inch hole in the middle is the part # 4-34 which is designed for 2k rated axles.

  • Brake Assembly For A 1972 Apache Mesa Camper
    To add new brakes to your 1972 Apache Mesa Camper you would need to replace the trailer brake assembly as well as the mounting flange. The brake assembly bolt measurements are 2-7/8 center on center so they would not be compatible with your current backing plate at 2-3/4 center on center. I recommend the Brake Mounting Flange for 1-3/4" Round Trailer Axles - 2K Item # 4-34 and Electric Trailer Brake Kit - 7" - Left and Right Hand Assemblies - 2,000 lbs Item # AKEBRK-2. You want to make...

  • 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 lugs...

  • Parts for a Custom 2K Axle with 58 Inch Spring Centers and 62-1/2 Inch Hub Face Measurements
    The hub face to hub face measurement is all going to depend on how you put it all together but I am sure you could get it to that measurement with the parts you mentioned. We do have 2,000 pound axles ready to go, see link, but they have a 72 inch hub face measurement which is the standard for that particular capacity. The hub face measurement will depend on the length of the axle tube you will be using. You should know that welding on a brake mounting flange such as # 4-34 requires a...

  • Brake Flange that Can Fit to Square Axle that is 1.5 inches by 1.5 inches
    You'd have to go with a brake mounting flange designed for a round axle since we don't have any specifically for square axles. Most likely some modifications will need to be made but since only people with experience installing brake flanges should perform this install they'll have a way to make it work. Using a flange with a smaller center hole like the part # 4-34 might be the way to go since it would give you more metal to work with to get it to fit.

  • Availability of Brake Flange Used on TRU74FR Spindle

  • Availability of 4 Bolt Mounting Flange for Electric Brake Assemblies
    It sounds like you are looking for a brake mounting flange for your trailer axle. For 4 bolt mounting flanges, we have the following plates available: For 3-1/2 inch axles: # 4-50 For 3 inch axles: # DM52415 For 2-3/8 inch axles: # 4-35 For 2-3/4 inch axles: # DM60124 For 1-3/4 inch axles: # 4-34 Brake mount flanges will need to be welded to the end of your axle and will provide a secure mounting place for the brake assemblies. I recommend having a qualified welder perform the installation.

  • Electric Trailer Brakes Compatible with 10 Inch Hubs
    The 7 inch brakes fit brake flange # 4-34 which has hole spacing 2-7/8 inches on center. The 10 inch assemblies have a the same 2-7/8 inch on center mounting holes # 4-35. It sounds like your brake flange is likely the standard size and you will simply use standard 10 inch brake assemblies like # AKEBRK-35. There is not a 9 inch assembly or any other assembly that will fit 3 inch on center flanges, so I hope you have the standard 2-7/8 inch flange.

  • Troubleshooting Installation of Electric Brakes With 4 Bolt Brake Flange
    The measurements for the brake flange and the bolt pattern on trailer brakes is a center to center measurement, not outside to outside. The electric brakes you have appear to be using the industry standard which is typically listed as 2-3/4" or 2-7/8" with the actual dimension being more like 2-13/16". I can't exactly tell by the pictures but it looks like the two measurements you have there are incredibly close so if you have not tried to install these I recommend double checking to...

  • How to Install Dexter Electric Trailer Brake Assembly on Trailer Without Brake Mounting Flange
    In order to install the Dexter Electric Trailer Brake Assembly part # K23-086-00 on your trailer you will need to install a brake mounting flange as well. Based on the photo you submitted, there isn't room to install a brake mounting flange on the axle but you should be able to install it on the stud just before where the grease seal seats. If the diameter of the stub you have is 1-3/4" then you can use the Brake Mounting Flange part # 4-34 otherwise you would need to fabricate something...

    I did some research online and it looks like your 2002 Jayco Kiwi 23B hybrid camper will have 2 torsion axles with 4 bolt brake mounting flanges and 10 by 2-1/4 inch brake assemblies. You should remove one of the wheels and a hub and check to be sure before ordering parts. You will also need to determine the manufacturer of the brake assemblies on your axles before ordering replacement parts to determine the correct parts that will fit the brake assemblies.

  • Parts Needed to Add Electric Drum Brakes to a 2003 Haulmark Trailer
    The first thing you are going to want to check is if the trailer axle has brake mounting flanges to attach brake assemblies to. A brake mounting flange will look like # 4-44-1 or # 4-34. If the trailer does NOT have these they will have to be welded on by a qualified professional with experience with installing flanges. It requires a special jig because the flanges have to be perfectly straight and concentric. You will also need the brake assemblies like you said, hub/drum assemblies,...

    You will need Hub Drums that have the hub built into the drum. For part # 23-47 you will need 7 inch Hub Drums, like part # 8-173-16UC3 and mounting flanges, part # 4-34, that will need to be welded to your axles. This size brake and hub drum assemblies are for smaller trailers. You will pick your hub drum based on your wheel and axle size, then you will pick the brakes that fit that hub drum.

  • How To Add Brakes To 2K Axles with BT8 Spindles
    The first thing you'll need to do is weld-on a brake mounting flange like the Brake Mounting Flange part # 4-34 to the spindle. Then, you can obtain new braking assemblies, the Electric Trailer Brake Kit part # AKEBRK-2. In order to use these, you'll also need new hubs/drums as well for which I recommend the Trailer Hub and Drum Assembly part # AKHD-545-2-1K. The 7" hub/drum assemblies are only available in the 5 on 4-1/2" pattern.

  • Parts Needed to Add Electric Drum Brakes to a 5 x 8 Utility Trailer
    We do have all the items you need to add electric drum brakes to your existing 2200-lb axle and the linked article outlines it all. But for making this process as easy and foolproof as possible you might consider simply replacing the entire axle with one that already has brake flanges, hub/drums and brakes. For example, etrailer Trailer Axle w/ Electric Brakes # e43SR is an 89-inch 3500-lb axle with 5-on-4-1/2 hubs and 10-inch electric brakes that comes complete with bearings, races and...

    To add trailer brakes to your 2016 TAG Max XL you will need to check if your current axle has a flange for trailer brakes, or not. If your axle does not have a flange you can measure the diameter of your axle to purchase the correct brake flange like # 4-34 and have a qualified welder install them on your axle. If your current axle has a flange already, it will most likely be a 4 bolt flange. To pick the correct hub and drum assemblies you will need read the numbers on your inner bearing,...
