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. 451290

  • 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.

  • Parts Needed to Add Electric Drum Brakes to a 16' Dual Axle Trailer
  • To install electric brakes on your trailer you need brake mounting flanges, brake assemblies, hub and drum assemblies, trailer wiring for the brakes, a breakaway kit, and a brake controller installed in your vehicle. You do want to install brakes on both sides of the axle(s) otherwise your trailer will pull to one side when your brakes are applied. We also recommend installing brakes on all of the axles that you have on your trailer. This helps to ensure that you have enough stopping...

  • Brake Assembly Replacement Recommendation for Dexter Assemblies 36-19-47
  • Based on what you described you have a standard 4-bolt trailer brake assembly bolt pattern. For brake assemblies that match that and the 4,400 lb axle capacity you have you'd want the part # K23-478-00 for the left hand side and part # K23-479-00 for the right hand side. For a brake flange you'd then want the part # 4-35 if you were also in need of that.

  • Electric Brakes for 2001 Jayco Eagle 12 SO Pop-Up Camper
  • Your 2001 Jayco Eagle 12 SO pop-up camper very likely has a 10" diameter x 2-1/4" wide hub and drum assembly, though you need to check to verify that is the case before ordering a brake assembly. If it does, I recommend Electric Trailer Brake Kit # AKEBRK-35-SA, which are self-adjusting brakes that are designed to work with 3,500 lb axles. It is also important that you have a 4-bolt mounting flange such as # 4-35 to mount your brakes; this particular flange is for 2-3/8" round axles....

  • Adding Electric Trailer Brakes to a 3,500 Pound 2001 Car Mate Trailer
  • The first thing to check for on the trailer is whether or not it has brake mounting flanges welded to the ends of the axles. A brake mounting flange on a 3,500 pound axle would look like # 4-35. If there are no brake mounting flanges they would have to be installed to add brakes to the trailer. The brake assemblies do not come with hub and drum assemblies so those would have to be purchased separately based on the bearing numbers on the current trailer hubs. The bearing numbers are stamped...

  • Replacement Brake Assembly Parts for 2800 lbs Philips/Dexter Axle with 1-1/4 Inch Deep Hubs
  • You will want the Replacement Brake Spring Set for Dexter 10" x 1-1/2" Electric Trailer Brake Assembly # K71-362-00. Then you will want the Replacement Trailer Brake Magnet Kit for 7" Brake Assemblies # BP01-068 due to the thinner hubs instead of the traditional 10 x 2-1/4 inch hubs. That guide for the anchor post is not available as a replacement part from any of our manufacturers. Your only other option is to replace the assemblies with the Dexter Electric Trailer Brake Kit - 10"...

  • How to Choose Brake Assemblies and Brake Controller
  • To determine the brake assemblies that will fit your trailer, you would need to know your axle's weight capacity, the size of your wheels, your mounting flange bolt pattern and the inside diameter and depth of your hub. I've left a link to our page with our selection of brakes for you to take a look at as well as a help article on adding electric brakes. If you get back to me with this information I would be able to tell you what you'll need. As for a brake controller, that is independent...

  • Replacement Boat Trailer Brakes Rated for 3,500 lbs

Based on the Dexter 8-247 number you gave we know you have a 3,500 lb Dexter 10" Hub and Drum Assembly such as part # 84546UC3. For a hub and drum that size the best option is the Hydraulic Trailer Brake - Dacromet because they are designed for marine applications with their corrosion-resistant dacromet coating and mount to a 4-bolt mounting flange such as # 4-35....

  • 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...

  • Can Brakes be Added to 3,500 Pound Dexter Trailer Axle
  • Yes, brakes can be added to your trailer and I've linked an article to help with the parts you'll need. The first thing you'll need is the brake mounting flanges welded to the axle, like you mentioned. The correct flange is # 4-35 however these need to be welded by a qualified welder because the mounting flange must be welded square and concentric. This is generally done using a jig at a trailer shop. I've linked our selection of hub and drum assemblies for 3,500 pound axles. You'll...

  • Brake Mounting Flange Recommendation for Dexter 3,500 lb Axle
  • Looks like you have a 3,500 lb Dexter axle without brake flanges. The correct brake flanges for that style of axle is the part # 4-35. 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...

  • Parts Needed to Add Electric Drum Brakes to a Trailer
  • The first thing you need to do is check the trailer axle to see if it has brake mounting flanges. It will look like the square part welded onto # R20384EZ. If the trailer does not have those they will need to be added by a professional with experience in welding on brake flanges because it is a precision job. For a 3,500 pound axle you would use # 4-35 sold in quantities of 1. You would need 2 per axle. You will also need to have hub and drum assemblies. For this I would need to know...

  • Replacement Hub/Drums and Brake Assemblies for Lippert Axle

I'll link you to our selection of hub/drums for a 3500 lb axle. Simply use the filters on the side of the page to narrow down your selections...

  • Recommended Trailer Brake Assemblies and Hubs to Add Brakes to 3,500 lb Axle
  • For your Cargo Mate trailer with 3500 lb axle, you will need the Electric Trailer Brake Kit # AKEBRK-35-SA. These will mount to the flanges on your axle using hardware # BRKH10B. If you don't have flanges, then I recommend the flange # 4-35 that will need to be welded by a professional with the correct jig. Because almost all 3500 lb axles from all manufacturers use the same spindle size, you can then use the Trailer Hub and Drum Assembly - 5 on 4-1/2 bolt pattern # AKHD-545-35-K or...

  • Parts Needed To Add Electric Brakes On Motorcycle Trailer
  • 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. The brakes I recommend for you are part # AKEBRK-35L-SA. These are self-adjusting 10 x 2-1/4 inch brakes and will work with 13, 14, and 15 inch diameter wheels. This is the brake for the left hand(driver side). For a brake...

  • For your Demco Kar Kaddy, the Demco Hydraulic Brake Actuator w/ Electric Lockout - Disc - Zinc - 2" Ball - 6,000 lbs # DM8605101 will work great. The Kodiak Disc Brake Kit - 10" Rotor - 5 on 4-1/2 - Dacromet - 3,500 lbs # K2R35D will not work well with the brake flange so you will want to upgrade the flange to the # 4-35 since the Kar Kaddy has a unique flange instead of the standard. The idler hubs # DM04369 will work well without any modifications. Then you will just need brake lines...

  • Parts Needed to Convert From Surge to Electric Brakes
  • The backing plate you are referring to is, I'm assuming, the brake mounting flange, which should be welded on. The dimensions of this are extremely important because it will determine the brake assemblies that fit. The Demco Trailer Brake Mounting Flange # DM60124 has a 2-3/4" pilot hole and has a 4 on 4-13/16" bolt pattern. This is uncommon compared to Brake Mounting Flange # 4-35 which is for 2-3/8" round axles and has 4 bolt holes which are 2-7/8" apart on center, which is what you...

  • Disc Brakes Recommendation For 3500 Lb Boat Trailer
  • The Kodiak disc brake kit you asked about, part # K2R35DS, will fit 3500 pound axles with wheel sizes 14 inches or larger. The 10 inch rotors have a 5 on 4-1/2 bolt pattern. The additional 1/2 inch would mean the wheels would indeed be mounted approximately 1/4 inch further out on each axle. The existing hubs along with the bearings and races would have to be removed. You mentioned that the axle has a 4 bolt flange already welded to it. I have attached a photo of how the brake mounting...

  • Where does a Brake Flange need to be Welded on a Spindle
  • Welding a brake flange on a spindle is not something we recommend most people doing. Most spindles have these welded on at the factory with specialized jigs and higher precision welding equipment that what even experienced do-it-yourselfers have. 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...

  • Brake Mounting Flange Location Measurement on Spindle # R20384EZ
  • We only have one spindle with the brake flange for me to measure. The EZ Lube Spindle 1.75" RD x 3" STUB # R20384EZ has a measurement of 1.23 inches from the step in the spindle to the outermost part of the brake flange. I've attached a photo to assist. The brake flange # 4-34 or # 4-35 needs to be welded perfectly perpendicular to the axle so it is recommended to have a professional with a jig do this welding. There is not a brake flange fit for the square axle spindle # SP20484.

  • 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.

If you do have the standard size spindle on your axle then you can very well use our Trailer Hub and Drum Assembly # AKHD-545-35-EZ-K which meets all of the criteria that you mentioned.
