Video Transcript for Redline Trailer Brakes 4-35 Review

Today we're going to be taking a look at a brake mounting flange for a 2 3/8" round axle. This trailer brake mounting flange gets welded to the end of the axle beam to provide a secure mounting place and support for the brake assembly. This part number includes one brake mounting flange. It's for use with a 10" brake assembly. The center hole diameter, that pilot hole. That's going to give us a diameter of 2.27".

You can see that's going to contain four bolt holes. These are going to be separated apart from one another on center by 2 7/8", and that's going to be the same separation for each one. That's a square design. It's a steel construction that has a thickness of about 1/4". Overall measurements going edge to edge this direction. It's going to measure 3 3/4", and again it's a square design so it's going to measure the same going in this direction, 3 3/4".

That's going to do it for today's look at the brake mounting flange for a 2 3/8" round axle.

Service was good and shipment was rite on time. One of the grease seals was bent in the shipment but I think it will work time will only tell. I was hoping that Dexter being made in America that they would use American made bearing also, they don't . The only other thing was I Thought I was getting bearing buddies but after looking back at the description I see that it wasn't , that is my mistake for not knowing better. I would have saved 18 dollars being I used my old grease caps instead. But over all I will use this company again great service. Keep up the great work.

  • Are Specs Available for Welding on a Brake Mounting Flange to a Trailer Spindle
    There is a special jig required to weld on brake mounting flanges such as # 4-35. 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 around. If not, the brakes will not wear evenly and will cause reduced braking performance. If not at the right depth the brakes will not be as effective and again, wear unevenly. Ideally you would take...

  • How To Determine What is Needed To Add Electric Brakes To Enclosed Trailer
    In order to add electric brakes to your trailer there are a few things needed. I have attached a link to a helpful article that explains how to add electric brakes to a trailer an what is needed. Some of the things you will need to know are the weight capacity of the axle(s), and if the axle has a brake mounting flange installed, similar to part # 4-35. If there is no brake mounting flange on the axle, you will need to have one welded on by a certified professional. You will then want...

  • Determining the Axle Capacity of a 2 Inch Square Trailer Axle
    The only way to know for sure is to find a stamp or plate somewhere on the axle with its capacity. If this isn't available you can use the bearing numbers to determine which spindles the trailer has and we can determine the capacities of the hubs that will fit. Another possible thing to check is if the axle has brake flanges how many bolt holes does the flange have? a 4 bolt flange it's likely a 3,500 pound axle or smaller. A 5 bolt flange is usually a 4,400 pound axle or larger.

  • Is there a Brake Mounting Flange for a Square 3500 Pound Trailer Axle
    When square axles are made brake mounting flanges with round holes are still used. It may require some additional steel when welding but your best option is # 4-35. Keep in mind that welding on a brake mounting flange properly requires a special jig and someone with experience in welding them on to ensure they are perfectly straight and concentric. Otherwise it can lead to all sorts of brake, tire, and other issues.

  • How to Find a Brake Mounting Flange for an 8 inch Rotor
    To find out if the Redline Brake Mounting Flange # 4-35 that you referenced will work for your application you will just need to take a few simple measurements. This mounting flange fits 2-3/8 inch round axles and will be welded to the axle. The bolt hole pattern that you will need to match to your brakes is 2-7/8 inches center-on-center as is demonstrated in the attached video and picture.

  • Recommendation For Replacement For Brake Mounting Flange
    I have brake mounting flanges that will work for you.

  • What Brakes Do I Need For My 3,500 Lb. Axles
    The Electric Trailer Brake Kit part # AKEBRK-35 are designed to be used with 3,500 lb. axles with 10-1/2" x 2-1/4" brake drums. In order to determine if these brakes will fit your trailer axle. You will need to do a bit of measuring. The brakes fit axles that have a 2-3/8" diameter, hubs compatible with 10" brakes and a 4-bolt brake mounting flange. If you do not have a 4 bolt brake mounting flange, you can use the Brake Mounting Flange for 2-3/8" Round Axle part # 4-35. As long as you...

    The Demco hydraulic drum brake assembly, # 40715, mounts to a standard 4-bolt mounting flange like # 4-35. The bolt holes are 2-7/8 inches apart on center. If measuring diagonally from a top hole to a bottom hole it is 4 inches on center.

  • Recommendation for Installation of a Brake Mounting Flange on a Trailer Spindle and Axle
    Welding a mounting flange, possible item # 4-35, is a very precise installation. The flanges need to be installed square and concentric to the hub and drum assembly and each other. If the flange is installed incorrectly rapid brake lining wear, improper braking, trailer dog legging, bearing failure, rapid tire wear and, worst of all, weakening of the axle can occur. Usually special jigs are used to install the flange. The jig will keep the flange square and concentric to the axle and...

  • How to Determine Correct Electric Trailer Brake Size
    We don't have any way of knowing the brakes you need for your Shorelander boat trailer but can tell you how to determine the right ones. To determine the brake assemblies that will fit your trailer, you need to know your axle's weight capacity, your mounting flange bolt pattern and the inside diameter and depth of your drum. For example, the Electric Trailer Brake Kit # AKEBRK-35-SA are for 3,500 lb axles, measure 10" diameter x 2-1/4" wide (so that is the drum size they fit in) and fit...

  • How to Choose Correct Replacement Electric Brakes
    To determine the correct brake assemblies that will fit your trailer, you need to know your axle's weight capacity, the size of your wheels, your mounting flange bolt pattern, which will be 4-bolt or 5-bolt and will depend on the diameter of your axle. For example, 4-Bolt Brake Mounting Flange # 4-35 will fit a 2-3/8" round axle. You are also going to need to measure the inside diameter and depth of your drum. I've added a link for you to a help article on what you need in order to electric...

  • 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.

  • Replacement Brake Mounting Flange and Assemblies for 2003 Wehaul Snowmobile Trailer
    Most 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.

  • How To Choose The Correct Brake Mounting Flange For Your Trailer Axle
    Absolutely, in order to install a 5 bolt brake mounting flange, you will need the Brake Mounting Flange for 3" Round Axle part # 4-44-1. This brake flange bracket is designed to work with an axle diameter of 3". If your axle is smaller than this, or you want a 4 hole mounting flange. You will need the Brake Mounting Flange part # 4-35 for a 2-3/8" axle and the Trailer Brake Mounting Flange part # 4-50 for 3-1/2" axle diameters. I recommend having a professional welder perform this task...

  • Trailer Brake Mounting Hole Pattern is Not the Same as Drum Bolt Pattern
    The bolt pattern of the drum has nothing to do with the mounting pattern of a brake assembly. The drum bolt pattern is going to have to match the wheels you are using. The brake mounting pattern needs to match the flange that it bolts to. There are 2 common brake mounting hole patterns; a 5-hole and a 4-hole. The 5-hole version looks like # 4-44-1. The 4-hole looks like # 4-35. etrailer brake assembly # AKFBBRK-35R-D uses the 4-hole pattern. So if you look at your brake mounting flange...

  • 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.

  • 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...

  • Trailer Brake Flange for a 3500-LB Axle
    Typically, 3500-lb axles have a 2-3/8" diameter. If this is your correct axle diameter, then the correct mounting flange for you is part # 4-35. If your correct axle diameter is in fact 3", then the correct mounting flange is part # DM52415. We do not have a 2-7/8" axle option. Either way, the flange will need to be welded on, so I recommend having a professional welder do this so they perfectly aligned.

  • Will Backing Plates be Needed When Installing Titan Disc Brake Kit on Lippert 3500 Lbs Axles
    The Titan Disc Brake Kit and BrakeRite Electric-Hydraulic Actuator - Tandem, 3,500-lb Axle, # T4843800, include caliper mounting brackets that are designed to mount to the 4 bolt brake flanges that are usually already on your axles. However, in some instances, these flanges may not be on the axle. In these cases, a brake mounting flange, like # 4-35, will have to be welded on to the axle to allow the caliper brackets to be mounted. It is recommended that brake flanges should be installed...

  • Can Trailer Brakes be Added to Motorcycle Trailer Axle
    When adding brakes to a trailer the first thing you will need is a brake mounting flange on the axle. If you do not have a brake flange I recommend part # 4-35. This should be welded in place by a professional welder because it needs to be square and concentric. Beyond that step we have to first determine what hubs/spindles you have on your trailer so that we can first fit a hub/drum (if available) to it and then install assemblies as well.

  • How To Determine Which Electric Brakes Will Fit On A 6x12 Utility Trailer Without Any Brakes
    I will need the bearing part numbers and the grease seal part number from your trailer so we can determine the correct hub drum assembly that is needed to install electric brakes on your trailer. The numbers needed for your bearings will be imprinted on the bearings and seals themselves. You would disassemble the hub and read the numbers off the bearings and seals. Remember which order they go in. Some trailer hubs have different size bearings on the inner and outer sides of the hubs. I...

    The Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKEBRK-35 has a mounting pattern that is typical for 3,500 lb axles. The center on center horizontal measurement of the mounting bolts are 2-7/8 inches and diagonal center on center of 4 inches. You can see this with the mounting flange # 4-35. I can't confirm the fit of the hubs on your trailer without knowing if the spindles on the axles are the standard length or not. The standard spindle length leading...
