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.

  • Can Self-Adjusting Electric Brakes be Used on 3,500 lb Dexter Axle
    You can absolutely use self-adjusting electric brakes on your trailer with 3,500 lb Dexter axles; the fact they are self-adjusting won't be a limiting factor at all, they just need to fit your hub. A 3,500 lb Dexter axle will use a 10" x 2-1/4" hub and drum, just like you mentioned, though you should verify that your drum is that size just to make sure. Also be sure that you have the correct brake flange; it should have bolt holes 2-7/8" apart on center, like the Brake Mounting Flange...

  • Are 10 Inch Electric Brake Dimensions Referring to Inside of Drum
    The measurement that is being referred to in regards to the size of electric brakes is the inside diameter of the drum. So for example, the Electric Trailer Brake Kit - 10" # AKEBRK-35-SA measure 10" diameter x 2-1/4" wide so that's the size of the drum they would fit. These will work on that size drum, fit a 4-bolt mounting flange like part # 4-35 and are rated for 3,500 lbs. The Mounting Hardware # BRKH10B is also needed for the Electric Trailer Brake Kit # AKEBRK-35-SA. In regards...

  • 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...

  • Why Were The Kodiak 204 Calipers and Pads Discontinued?
    I wish I had a good answer for you, but since Kodiak was bought out by Dexter it seems they discontinued the 204 caliper in favor of using the 225 calipers. They both worked on 3500lb axles but the 225 was also able to be used on larger axles up to 6000lbs. You can replace your 204 calipers with the 225 using mounting bracket # KCMB10RD if you have 3500lb axles, or # KCMB12D if you have 5200-6000lb axles. You will then need the new calipers # KDBC225DAC and pads # K225CP. I included...

    We do have what you need to install electric brakes on your trailer, and so long as your current hub and drums are 10" diameter x 2-1/4" wide (which is standard for 3,500 lb axles) and you have a 4-bolt brake mounting flange such # 4-35 you can use the Dexter Electric Trailer Brake Kit # 23-26-27. If you don't have that brake mounting flange you would need to get it welded onto your axle beam. Other parts you need for this are the Brake Adjustment Spoon # W80630 and Hopkins Engager Push-To-Test...

  • 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.

  • 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.

  • 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.

  • 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...

  • 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...

  • 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...

  • 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...

  • How to Add Electric Over Hydraulic Disc Brakes to a Boat Trailer with 3,500 Lb Axle
    I am assuming you are referring to an electric over hydraulic disc brake system? If this is the case then you are going to need the following if you don't already have them which are a brake mounting flange, disc brake assembly, brake line kit, electric over hydraulic actuator, and a breakaway kit. I have attached my recommendations on each of the following parts below. We also have a help article that explains this whole process which I have attached for you. Brake Mounting Flange:...

  • 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...

  • Can Electric Trailer Brakes Be Added To A Boat Trailer
    With the quality of materials and better wiring insulation on modern electric trailer brakes, you can definitely use them on a boat trailer like your single axle Custom Performance trailer for your Catalina 22 sailboat. I would still recommend unplugging the trailer connector from your vehicle when backing the trailer in the water as an extra layer of security. Now to determine the correct brakes, and components necessary you will need to find a few key bits of information on your trailers...

  • 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...

  • Parts Needed to Add Brakes to SureTrac Trailer with 3500-lbs Axle
    When adding brakes to a trailer the first thing you will need is to determine if there 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. For the brakes I recommend using the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKEBRK-35-SA, which are self adjusting brakes that will be something...

  • 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...

  • Parts Needed to Convert From Hydraulic to Electric Brakes for 3,500 lb Axles
    Thanks for that info, and based on what you said, it sounds like you have a standard brake mounting flange like # 4-35 for a 3,500 lb axle. I do recommend just double-checking the inside diameter of your drum, as electric brakes for 3,500 lb axles fit drums that have an inside diameter of 10 inches. Assuming that is correct, we have exactly what you need to outfit your tandem axle trailer with electric brakes, which are the following parts: - Two (for both axles) of the Electric...

  • Can Electric Brakes With Parking Brakes for 3,500 lb Axle Work on 3,000 lb Axle
    We do offer electric brakes with a parking brake for 3,500 lb axles, and so long as you have a 4-bolt mounting flange like part # 4-35 and you have drums that measure 10" diameter and 2-1/4" deep you can use these brakes. The correct brakes for this are the Dexter Electric Trailer Brake Kit w/ Parking Brakes # K23-086-087-00. If you don't have an adjustment spoon you will also need Brake Adjustment Spoon # W80630.

  • 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.

  • 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 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. If your axle is a different diameter just let me know what it is and what your brake/rotor...

    We do not have a kit with all of the components needed to add electric trailer brakes to your Dolittle 6' x 12' cargo trailer but I would be happy to recommend the products needed. Since your trailer has a GVWR of 2990lbs it more than likely has 3500lb axles but you will want to check the axle tag located on the center of the axle to be sure. First you will want to make sure that there is a brake mounting flange installed on the axle. This is a 4-bolt flange that will be located directly...

  • Are Kodiak 225 Calipers Compatible With 13 Inch Trailer Wheels
    According to Dexter who purchased Kodiak awhile back, the 225 calipers are a bit larger than the 204, which means that they aren't compatible with 13 inch wheels. If you went with the 225 caliper, you would need to go with a 14 inch wheel. If you could reply with the wheel bot pattern (see linked article showing how to determine this) and the current size and load rating tire you're using, I'd be happy to recommend a wheel/tire combo for you.
