Expert Answers about Trailer Brakes


  • Recommended Disc Brake Hub and Rotor System for 3,500 lb Axle on Ranger Trailer
  • For your 3,500 lb axle conversion to disc brakes we have the Titan Disc Brake Kit and Swing-Away Actuator w/ Electric Lockout - Single, 3,500-lb Axle # T4843300 or the Titan Disc Brake Kit and Leverlock Actuator w/ Electric Lockout - Single, 3,500-lb Axle # T4843100 that are my top recommendations. Both come with the disc brake compatible actuator, and everything else you need as far as components. If you already have brake lines from drum brakes, then you can simply use the disc brake...

  • Mounting Bolt Pattern on etrailer.com Electric Brake Kit # AKEBRK-35-SA
  • The etrailer.com Electric Trailer Brake Kit # AKEBRK-35-SA referenced in your question feature a 4 bolt pattern on the assemblies. The bolts are spaced apart on center at just about 2-13/16 inches. This is a standard 4 bolt pattern that is found on most 3,500 pound assemblies. I have attached an image to assist.

  • etrailer.com Hub/Drum Assembly and Brakes for a 3500 lb Rockwell American Utility Trailer Axle
  • Yes, the Trailer Hub and Drum Assembly # AKHD-545-35-EZ-K is what you would want to use in conjunction with the 10" Electric Trailer Brake Kit # AKEBRK-35. From the picture you sent in you do have the 4 bolt mounting flange that allows you to use the 10" brake kit. Just check and be sure that your current hubs use the standard inner bearing # L68149, outer bearing # L44649, and grease seal # 58846 and you are good to go on that end! Please note that you also need to run the wiring...

  • Kodiak Disc Brake Kit Recommendation for Trailer with Dexter 7,000 lb Axles
  • For your trailer that has Dexter 7,000 lb capacity axles the Kodiak Disc Brake kit I recommend is the part # K2HR712D. You'll need the seal part # RG06-070 and the bearings part # 25580 and # 14125A and you'll be set. I recommend this kit because all of the components are Dacromet coated which means they'll do an excellent job resisting corrosion. Then for the actuator kit you'd want the HydraStar setup part # HBA16-252-82. This comes with the needed brake lines and breakaway kit to...

  • Recommended Electric Trailer Brake Conversion for Tandem Axle Boat Trailer with 4,200 lb Axles
  • For your conversion from surge brakes to electric brakes, you can simply remove your current hubs and then remove the hydraulic brake assemblies. Then install the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKEBRK-35-SA and reinstall your hubs. Then you will run one wire from the magnet to ground on the frame and the other wire to the 7-way trailer connector. I recommend using # 10-1-1 wire sold by the foot and then also using the...

  • Will Taskmaster Wheel LT589DMPWX Fit on Kodiak Disc Brake Kit K2HR712
  • The wheel cradle, where the wheel pilot fits onto the hub, for the Kodiak Disc Brake Kit # K2HR712 referenced in your question has a diameter of 4.745 inches. The wheel you are looking at part # LT589DMPWX has a pilot diameter of 4.76 inches so this would be close enough to fit.

  • Do Trailer Hubs # 84546UC3-EZ and # AKHD-550-35-K Fit Same Spindle
  • Both hubs you mentioned fit the same size spindle so they would be interchangeable, but since you want a 5 on 5 inch bolt pattern the hub/drum you'd want is the part # AKHD-550-35-K actually. I also attached a help article on converting a trailer to electric over hydraulic drum for you to check out as well.

  • What Does Kodiak Disc Brake Kit Fit
  • The Kodiak Disc Brake Kit # K2R1058D11E will only fit a very specific idler hub from Dexter, the Dexter 008-430-03 and is designed for 16" dual wheels and has an 8 on 6-1/2" bolt pattern. Without seeing your specific application I can only guess but it sounds like this is not what you have on your trailer so you should definitely make sure you find out your precise axle and hub. While we do not have a video specific to this kit at the moment I did link a video which displays how a disc...

  • How to Determine Correct Replacement Disc Brakes for EZ Loader Boat Trailer for Salt Water
  • I can let you know how to determine what disc brakes you need although we do not have any type of database with parts based on year, make and model of trailer and I was unable to find any reference to a model TRSX240. To get the right replacement disc brake assemblies you need to know the weight capacity of your trailer's axles, the number of bolts in your brake mounting flange (like in the accompanying photo) and your bolt pattern for the rotors to slip over. If you are unsure of what...

  • Recommendation for Adding Electric Trailer Brakes to Trailer with 3,500 lb Axles & 5 on 5 Inch Hubs
  • For your 3500 lb axles, I recommend starting with the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies # AKEBRK-35-SA. These assemblies will self-adjust to ensure you have the best braking without needing to manually adjust them every few months. Then for your 5 on 5 inch hubs, I recommend the Trailer Hub and Drum Assembly - 3,500-lb Axles - 10" Diameter - 5 on 5 # AKHD-550-35-K. If you have the spindles with the integrated grease zerk, then you will...

  • Converting Hydraulic Brakes on M105a2 Military Trailer to Electric Brakes
  • To get you the correct fit for your M105a2 trailer, I need to know what is currently on your trailer. We've seen a wide variety of axle capacities from 5,200 lbs to 10,000 lbs. If you can help me with drum/hub dimensions, I can see what we have that may be compatible with your specific trailer. For instance, if you have 12-1/4 x 3-3/8 inch drums, then the Electric Trailer Brake Kit w/ Dust Shields - Self-Adjusting - 12-1/4" - Left/Right Hand - 10K # AKEBRK-10 would be a great option....

  • What is the Correct Braking Assembly for the Dico 15637 Hub/Drum
  • I do have a way for you to determine if the Electric Trailer Brake Kit part # AKEBRK-35-SA will work on your trailer but I do not have any reference to a Dico 15637 Hub/Drum therefore you will need to do a bit of measuring. For starters, you will need to count the number of holes on your brake mounting flange as this assembly uses a four bolt brake mounting flange. Once you have confirmed that the brake mounting flange is compatible you will then need to measure the contact surface inside...

The brakes you need are the Electric Trailer Brake Kit # AKEBRK-35-SA which measure 10" x 2-1/4" and have a 4 bolt flange mounting pattern. I also recommend replacing your hub and drum assemblies as well. For this the Trailer Hub and Drum Assembly # AKHD-545-35-K should work but you will want to verify that your trailer currently uses inner bearing # L68149...

  • What is the Four Bolt Brake Mounting Flange for 8,000 Lb Axles
  • The four bolt brake mounting flange for 8,000 lb trailer axles is going to be more or less an industry standard. This industry standard is 3-5/8" across left to right on center and 3-7/16" top to bottom on center. This could very well vary 1/16" depending on where you measure but rest assure if you have an 8,000 lb trailer axle with four bolt brake mounting flange the Electric Trailer Brake with Dust Shield part # AKEBRK-8L should be the correct braking assembly for you.

  • Disc Brake Conversion Kit for 2019 Keystone Raptor 351
  • The Dacromet Kodiak Disc Brake kit part # K2HR712D that you referenced is the place to start for your 7k Dexter axles. Dacromet resists rust much better than E-Coat so this would be the preferred route. Since this does not come with bearings, seals or caps you'd also need the # DBRKHW7 to provide all of that. The best EOH actuators are the Hydrastar actuators like what comes with the kit # HBA16-252-82. These react the quickest and provide the most reliability. This kit also comes with...

  • Upgrading Electric Trailer Brakes to Self-Adjusting Assemblies One Axle at a Time
  • You can absolutely upgrade your manual electric trailer brake assemblies on your tandem axle trailer to self-adjusting brakes like the 10 inch # AKEBRK-35-SA or the 12 inch # AKEBRK-7-SA. As long as the assemblies on each axle match you can update your assemblies over time. There is no problem with having manual brake assemblies on one axle and self-adjusting brake assemblies on another axle. You simply need to remember to adjust the manual brake assemblies until you change them to the...

  • Your spindle dimensions are the standard 3,500 lb axle dimensions which is exactly what the Kodiak Disc Brake Kit # K2HR35DKG that you referenced is designed to fit so this kit will fit and work well for you. This kit would work really well for a saltwater/freshwater application. The Dacromet and KodaGuard finish do an excellent job preventing corrosion. The bearings and seals of this kit are sold separately so you'll need the part # RG06-050 for seals and part # L68149 and # L44649 for...

  • Dexter Self Adjusting Brake Assemblies for 2006 Casita Travel Trailer with 3,500 lb Axle
  • I don't know which specific 2006 Casita travel trailer you have, but if your Dexter axle is a 3,500 lb capacity axle then the brake kit part # 23-468-469 that you referenced would be the correct kit. Typically you can find the axle capacity on a plate near the coupler of the trailer with the VIN or you can measure the diameter of the axle. If it's 2-3/8 inch in diameter then you do have a 3,500 lb axle and this kit is the correct setup.

  • Are Hub/Drums Sold Separately from Trailer Brake Assemblies
  • Hub/drums are sold separately from the brake assemblies we carry. It's not always needed to replace both at the same time so we offer them separately. You'd have to look at the spindles on the tow dolly to see if they have brake flanges to determine if a set of brakes could be installed. I attached a help article on what it takes to add brakes to a trailer that would walk you through the entire process as well.

For the disc brake kit that comes with hub/rotors I recommend the Kodiak Kit part # K2HR89DD as it is Dacromet coated which will prevent corrosion. Then for the electric over hydraulic kit you'd want the HydraStar Electric-Hydraulic Actuator w/ Line Kit for Disc Brakes # CAR-HBA16-2. This comes with everything needed to install the actuator and have it functional. The included actuator...

  • Is a Gasket Normally Used When Installing Trailer Brake Assemblies
  • When installing brake assemblies like the Electric Trailer Brake Kit part # AKEBRK-35-SA that you referenced a gasket is not normally used. Normally the assemblies mount directly to the flange. I attached a review video for this kit that shows them installed right at the 7:30 mark and you can see that our installer does not use a gasket of any type.

  • What is Needed to Convert to Electric Over Hydraulic Disc Brakes
  • The Kodiak Disc Brakes # K2R1058D11 may work with your 10,000 lb Dexter axle but you will need to verify this. To do that you can take apart your hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use a digital caliper such as # 301-17068 and measure your spindle to the thousandths of an inch where the bearings ride. You can use the photo I've attached...

The added width is the same added width of any slip-on style rotor.

  • How to Initially Adjust Dexter Nev-R-Adjust Electric Trailer Brakes
  • You can initially adjust your Dexter Nev-R-Adjust Electric Trailer Brakes # 23-458-459 but the adjustment tool you are using might just be too thick to get to the adjustment wheel. You should use something that allows you to more easily access that wheel (as shown in picture) such as a flathead screwdriver. If you go to the linked video and forward to about the 14:15 mark you can see a flathead screwdriver being used to make an initial adjustment.

  • Will Brake Assembly with 5-Bolt Mounting Pattern Fit 4-Bolt Mounting Pattern
  • If your current brake assemblies have a 4-bolt mounting pattern then you likely need the Nev-R-Adjust Brake Kit # 23-468-469 (10") for 3,500 lb axles. Since the Brake Kit # 23-464-465 (12") that you referenced has a 5-bolt mounting pattern it will not fit as a replacement for your current brakes. If you need 12" brakes and you have a 4-bolt mounting pattern then we do have the Brake Kit # 23-105-106-09 but it is manual adjust brakes.

  • Ways to Determine Trailer Axle Capacity
  • If your trailer is rated at 5,200 lbs most likely you have axles that are rated less than that individually. Typically on the VIN plate of the trailer the axle capacities will be listed. Common axle capacities are 5,200 lb, 3,500 lb, and 2,200 lb so most likely you probably have 3,500. But you can also measure the diameter of them too to determine this. - 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4 inch diameter - 3,500-lb Axles: 2-3/8 inch diameter - 5,200-lb - 7,200-lb Axles:...

  • Your current drums will work fine with a set of electric assemblies installed instead of the hydraulic ones you have now. We actually have a kit designed to upgrade a trailer's 4-way wiring to a 7-way. For that you'd want the part # ET7WK. From the brake output pin of the included junction box you'd run 10 gauge wire like part # 10-1-1 (sold by the foot) to the brake assemblies.

So if you do have a 5-bolt brake mounting flange, your hubs are 12" x 2" and you have an axle that is rated for between 5,200 lbs to 7,000 lbs the Electric Trailer Brake Kit - Self-Adjusting # AKEBRK-7-SA will work for you.

  • Troubleshooting Trailer Brakes that Hum But Do Not Lock Up
  • The humming sound you hear from your trailer's electric drum brakes is a good sign. It means that the brakes' magnets are being energized by the output from the trailer brake controller in the vehicle. Most likely your brakes aren't adjusted properly and that's why they aren't grabbing like they should. When a drum brake is adjusted correctly there will be slight drag on the drum when you rotate it by hand. You should be able to hear and feel this drag. Try adjusting your brakes so...

From there the brakes will continue to set themselves to the proper tightness as you power them when towing.

  • Does Going with Higher Rated Brake Assembly Give you Additional Braking Strength
  • The magnets between differing trailer brake assembly capacities aren't more powerful than each other so much as they are different in sensitivity. You don't gain any power going with a higher rated assembly than you need. You actually just end up with a harder to adjust braking setup. It will seem like either the brakes are applying to hard or too soft without any middle ground. That's why your best option is to go with the exact capacity you need.

  • Do Trailer Brake Calipers Need to Face Certain Direction
