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 have a 2004 Honda trike that I built a pull behind trailor for! After pulling it loaded it was hard to stop safely! This brake assembly along with the Redarc brake controller done the JOB! now it stops safely

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!!!

I'm adding electric brakes to my boat trailer so I need flanges for mounting the back plates. Not yet installed but it looks like they're going to fit and work fine.

Exactly what I needed to add electric brakes on my Tow Dolly.
by: Doug J.07/25/2014
4-34 four bolt mounting plate is an excellent replacement for my 1997 Coleman Fleetwood Bayports popup campers that I am close to finishing a restoration process on. They fit perfectly! Very happy to purchase an excellent product from the fastest shipper I have ever come across. I am blown away by the professionalism with this company!
Thanks

- 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...
view full answer... - A Professional Should Install Trailer Brake Mounting Flange # 4-34You 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.
view full answer... - 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.
view full answer... - Reason for Dimples on Redline Brake Mounting FlangeThe dimples on the Brake Mounting Flange # 4-34 are a result of the manufacturing process for this part. The machine that formed/cut the brake flange left dimples behind. They don't play any role in how the brake flange functions.
view full answer... - How to Find the Correct Brake Mounting FlangeCapacity 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...
view full answer... - Brake Mounting Flange That Fits 2,000 lb AxleSo 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...
view full answer... - Electric Trailer Brakes for 4-Bolt Flange 2-5/8" x 3-5/8" ApartI 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.
view full answer... - Brake Assembly For A 1972 Apache Mesa CamperTo 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...
view full answer... - Brake Mounting Flange Availability with 1-3/4 inch Hole for Use with Titan Brake Kit T4843300The 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.
view full answer... - Adding Brake Flanges To An Aluminum Trailer with 2,200 lb AxlesWhat you will want to do is purchase the part # 4-34 as this is a brake mounting flange designed for 2.2k axles, provided your axle is a 1-3/4" round tube. The brake mounting flange needs to be welded on perfectly square and concentric and if it is off by even 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...
view full answer... - Brake Mounting Flange Recommendation for Fitting a 1-3/4 inch Diameter AxleFor 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...

view full answer... - How to Find Wheel Bolt Pattern to Find the Correct Replacement Trailer BrakesThere 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...

- Brake Flange that Can Fit to Square Axle that is 1.5 inches by 1.5 inchesYou'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.
view full answer... - Parts for a Custom 2K Axle with 58 Inch Spring Centers and 62-1/2 Inch Hub Face MeasurementsThe 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...

view full answer... - Availability of 4 Bolt Mounting Flange for Electric Brake AssembliesIt 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.
view full answer... - Can a Brake Flange Be Added To a Trailer Axle With Idler Hubs To Add Electric BrakesAs I do not see that we currently have a trailer axle with a 93" hub face to hub face you are going to be best to have the brake flange welded in place. To ensure this is done properly you will want to find a trailer shop with a jig to ensure the brake flange is welded on in the correct position and straight on the axle to prevent misalignment on the axle. Here is a list of the different sized brake flanges you will need to select from. Brake Mounting Flange for 1-3/4" Round Axle # 4-34 Brake...
view full answer... - Electric Trailer Brakes Compatible with 10 Inch HubsThe 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.
view full answer... - Troubleshooting Installation of Electric Brakes With 4 Bolt Brake FlangeThe 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 FlangeIn 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...

- Can 7" Hydraulic Brakes Be Replaced With Electric Brakes? The Electric Trailer Brake Kit # AKEBRK-2 is designed to fit a Flange # 4-34 which spaces the mounting holes 2-7/8" on center. As these are within 1/8" of the dimensions you listed I recommend rechecking the measurements for verification. I do not recommend drilling out the holes to increase the size as this could weaken the flange and cause another issues. Instead if your holes are a different pattern you can replace your flanges for the correct size flange. I recommend using new Mounting...
view full answer... - Can I Put Hydraulic Brakes on a 2,000 lbs Axle?Yes and no. The issue with 2,000 lbs axles like the Dexter Trailer Axle item # T20BTR-7258 is that they don't come with a brake flange item # 4-34. You can add one but this is something you will need to rely on a professional welder to do if you don't have experience. If you would like to give me some dimensions of the axle you're needing and your lug pattern I would be happy to make some recommendations for you. Feel free to email me directly.
view full answer... - How to Determine Electric Trailer Brakes For Forest River Viking TrailerWhile I couldn't find any specifics on the brakes your 2015 Forest River Viking travel trailer needs, we can help you determine the right ones. To find the correct brakes, you just need to know the weight capacity you need, what brake mounting flange bolt pattern you have, and the inside diameter and depth of your drum. For example, the Electric Trailer Brake Kit # AKEBRK-2 are for 2,000 lb axles, measure 7" diameter x 1-1/4" wide (so that is the drum size they fit in) and fit a 4-bolt...
