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

  • 10 Inch Electric Brake Assemblies for Boat Trailer
    Thanks for all that info, and the hole spacing you mentioned for your brake mounting flange means you have a standard 4-bolt flange like Brake Mounting Flange # 4-35. Based on that and the 10 inch drums you have then the brakes you need are for 3,500 lb axles and for that I recommend the Electric Trailer Brake Kit # AKEBRK-35-SA. These are self-adjusting electric brakes that measure 10" x 2-1/4" and will work with your brake mounting flange and 14 inch wheels. To install them you'd...

  • Recommendation For Replacement For Brake Mounting Flange
    I have brake mounting flanges that will work for you. We have several different types and sizes so you will need to find the right size and then have it welded on by a licensed professional welder. For example, for a 2-3/8 inch round axle we carry a Redline Brake Mounting Flange, Item # 4-35. I am attaching a link to an article, a video, and our available inventory for you to check out.

  • 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...

  • Replacement Hub/Drums and Brake Assemblies for Lippert Axle
    A replacement hub and brake assembly will work well with your existing axle if you choose a hub/drum that's compatible with the spindles on your axle, if the replacement hub drum and your existing hub use the same inner and outer wheel bearings and the same wheel bolt pattern, and if your existing axle has a brake mounting flange on it (see photo). 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...

  • 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.

  • Adding Electric Brakes to a 1997 Dutchmen Pop Up Camper
    Installing electric brakes on any trailer isn't too hard actually. All you have to do is mount the brakes (which requires a brake mounting flange), install a hub and drum assembly, and then run some wiring and a breakaway kit and your trailer is good to go. On your vehicle side you need a 7-Way connector and a brake controller to activate the trailer brakes. Most likely you have a 2,000 lb axle (which you can verify by looking in the middle of it for a stamp) so you need the mounting...

  • Recommended Disc Brakes for 3,500 lb Axles
    There is a little bit of information from Kodiak brakes that has some tests that I will link you to separately. We do consider Kodiak to be top-notch and for a 3,500 lb idler hub, I recommend the following braking system: - Kodiak Disc Brake Kit - 10" Rotor - 5 on 4-1/2 - Dacromet and KodaGuard - 3,500 lbs # K2R35DKG These will fit over your hubs so long as they have a 5 on 4-1/2" bolt pattern, which is pretty standard, though I'll link you to a help article to figure out how to determine...

  • 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...

  • 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...

  • 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...

  • 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.

  • 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...

  • 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.
