  • Saves Time on Install: Pre-assembled hub-rotor kit mounts easily with bearings and seals included.
  • Built for 3,500-lb Axles: 10-3/16" rotors with 5 on 4-1/2" bolt pattern fit 14" wheels and 1/2" studs.

Features to know about

Upgrade Dragging or Weak Brakes: Complete 3,500-lb Disc Kit with Hub and Rotor

If your old brakes are worn or pulling, this DeeMaxx kit gives you a full upgrade in one box. Each 10-3/16" rotor is built into a 1-piece hub-and-rotor assembly that keeps debris out and reduces uneven wear. The kit fits 3,500-lb axles with a 5 on 4-1/2" bolt pattern and includes inner bearing L68149 and outer bearing L44649 already installed. With ceramic brake pads and a stainless steel piston, braking feels smooth and consistent every time.

Built for Salt, Spray, and Launch Ramps: Maxx Coating Resists Over 1,000 Hours of Corrosion

Boat owners and coastal haulers deal with rust constantly. DeeMaxx solves that with their Maxx coating on the hub-rotors, calipers, and brackets—tested to last more than 1,000 hours in salt spray. Drainage holes in the hat section let water escape so the parts dry fast and corrosion can’t set in. This marine-grade finish outperforms zinc and Dacromet coatings for long-term protection around water.

Cooler Running, Longer Lasting Brakes: Vented Rotors Disperse Heat Fast

When brakes hold too much heat, they fade and wear out early. DeeMaxx uses vented rotors with extra drainage holes to shed heat quickly and prevent moisture buildup. The cooler they run, the better they stop—and the longer your pads last. It’s the same ventilation concept that helped these brakes pass the SAE J2681 automotive performance test for friction consistency.

Easy Bolt-On Setup: Pre-Assembled Hub/Rotor with Laser-Etched Instructions

DIY installers appreciate how straightforward this kit is. Each side comes preassembled with bearings, races, seals, wheel bolts, lug nuts, caps, calipers, and brackets—everything needed for one axle. The caliper bracket uses a side-support design to take the load off the bolts for longer service life. Laser-etched bleeding instructions on the calipers mean setup and maintenance are simple without needing a separate manual.

Reliable Performance Backed by a 7-Year Warranty

High-quality cast iron construction and automotive-grade parts make these brakes tough enough for demanding use. With a 3,500-lb axle capacity, 4-bolt flange fitment, and 1/2" wheel bolts, this kit provides strong stopping power with less upkeep. A 7-year warranty backs up that durability so you can tow confidently season after season.

I'm really sorry to hear that this happened to the bolts, Joey. It looks like our customer service team got you set up with replacements. If you ever need anything else in the future, please let me know!

Great product was very easy to install. The only thing left is to bleed the system

I purchased this to replace what the OEM had on my trailer. Easy install, but had a probem with it after install. etrailer could not help determine how to fix the issue, but gave me the number to the manufacturer. After several calls to DeeMaxx with no reponse I figured it out.

@John It is great to hear they are working well for you, and we were able to get you the parts needed after arrival. What trailer did you end up replacing these on?


by:

Has been reliable for 1 year



by:

Well Designed and build. I took some time to remove old set - it was rusted in place reel good. But install of the new set was very easy.
The improvement in braking is very significant i am controlling brakes with electric/hydraulic actuator and the system works just like brakes on the car - very precise and sensitive.



by:

Awesome people to work with. Finding the right trailer parts isn't easy. Amy J has helped me out quite a few times. This is where I will get all of my parts.



by:

I have not had much time on the road with these but from day 1 it was obvious I made the right choice. The items came in packaging that I would rate at 4 stars as there were some concerns but nothing drastic. The install was straight forward and everything went together as intended. I like the better braking control with the new system that works much better than the old set. My trailer is 2019 and the rotors were badly rotted, the calipers worked but were hanging up but these are a total game changer. Brakes work great!



by:

Fit perfectly on my EZ Loader Tandem Axle Trailer from 2008



by:

I bet they are nice, if shipped and re-sold by a competent company. Unfortunately, we're dealing with Etrailer here. Well... on this one, the last order I ever make with them. Crappy packaging means the rotors were free to make minced meat out of everything else inside the boxes. Due to life, it was a year before I was able to install them on the trailer. On top of it all, they decided it would be a great idea reward the hard-earned money I spent with them by spamming me, sending me unwanted unsolicited email until I threatened them with a lawsuit (CAN SPAM act).
I ended up visiting the local Tool store popular in the Northern and getting the parts to repair what Etrailer's incompetence in packing wrought.

  • Converting From Hydraulic Drum Brakes to Disc Brakes
    Hi Mike; can you send me your axle information? Is it a 3,500 lb axle? If I had to guess it is likely a 3,500 lb axle on there right now. Assuming you have the standard 3,500 lb bearing combination you can use the DeeMaxx Disc Brake Kit # DE66YR. This uses # L68149 inner and # L44649 outer bearings. You already have the hydraulic lines so the only other thing would be an actuator for disc brakes. Assuming you want a coupler for a 2" ball and have a 3" wide tongue the # DM62VR you looked...

  • Looking For New Disc Brake Kit For 2020 Continental Boat Trailer
    Hey Ryan, thanks for reaching out. We certainly should have a disc brake kit that will work for you, but there is no way to know exactly what kit you will need based on the make and model of trailer. Trailer manufacturers just do not make this kind of info available online. Specifically, I will need to know your axle weight capacity, and your inner/outer bearing sizes. This way we can be sure you get the right brake assembly, and correct hubs for your trailer. For example, what we see...

  • Marine Grade Surge Brake Kit Recommendation for a 16' Boat Trailer
    Hey Stephen, thanks for reaching out! I believe you have a 3,500 lb axle so I'm going to base my recommendations off of that, but it would be best if you verify this on your own. You can see the axle rating either on the tag near the tongue of your trailer or on the tag in the middle of the axle itself. We have some drum brakes with a dacromet finish, but there aren't any hub/drums with a marine coating so I recommend going with some disc brakes; specifically the DeeMaxx Disc Brake Kit...

    Hey Gene! Those don't quite look like 10" brake assemblies but I can't say for sure from the picture. If you have a 3,500 lb axle with # L68149 inner and # L44649 outer bearings than the DeeMaxx Disc Brake Kit # DE66YR will work. If that is a straight spindle with # L44649 inner and outer bearings you need the Kodiak Disc Brakes # KOD27FR instead. These are designed for 2k axles and have a 5 on 4-1/2 bolt pattern with an 8" rotor diameter. Bearings and seals are included with both, and...

  • DeeMax Disc Brake Kit Recommendation for Dual Axle Trailer with Lippert 3,500 lb Axles
    Hey Gary, thanks for all of the info on your axle. From that I can tell you have a 3,500 lb trailer axle with a 5 on 4-1/2 inch bolt pattern so the correct DeeMax disc brake kit would be the part # DE66YR. Then for a electric over hydraulic actuator kit the best option is the Hydrastar part # HBA16-252-82 as it comes with the best EOH actuator that is the most reliable and quickest reacting plus it comes with all of the electric components and brake lines so it would cover everything...

At this point your only option will be a whole new brake kit with rotors, calipers and brake pads. For that I recommend the following: - DeeMaxx Disc Brake Kit - 10" Hub/Rotor - 5 on 4-1/2 - Maxx Coating - 3,500 lbs # DE66YR This is a complete brake kit for a 3,500 lb axle.

  • Can The Demco Hydraulic Brake Actuator DM72VR Be Used With Disc Brakes?
    Hey Doug, thanks for reaching out. So the # DM72VR actuator you mentioned is only for drum brakes, you can't use it with disc brakes. If you want to run a disc brake setup, you need to use the # DM62VR actuator instead. They operate at a different PSI. That said, I see you already ordered the # DM72VR drum brake actuator, so if you intend to use that we should definitely have a drum brake kit for you, but I'll need a bit more information in order to be sure you are getting the right thing....

  • Can DeeMaxx Disc Brake Kit # DE42FR Fit Spindle with Bearing Numbers LM67048 and LM11949
    Hey Doug, your bearing numbers don't match up with current 3,500 lb trailer axle bearing configurations so I don't believe we'd have a set of hubs for your axle that would work. With that said if you somehow did get idler hubs that ift and the bolt pattern was 5 on 4-1/2 inch the # DE66YR could in theory fit but you'd need to have brake mounting flanges on the spindle currently. I attached a picture of a spindle that has a brake mounting flange for you to compare to what you have on your...

  • Can DeeMax 3,500 lb Axle Hub/Rotors Fit on 4,400 lb Trailer Axles
    Hey Gary, this is a great question but it comes down to what brand axle you have. The Dexter 4,400 lb axles use the same bearings as the 3,500 lb axles so your current DeeMax rotors # DE66YR would work but if instead your axle is a Lippert or AL KO brand axle they would not transfer as they use a different bearing set. If you can find out your axle brand and let me know I'll be able to help further if needed.

  • Does The DeeMaxx Disc Brake Kit DE66YR Use The Single Disc Brake Assembly DE89YR?
    That is an extremely good question, Jim. The DeeMaxx Disc Brake Kit - 10" Hub/Rotor - 5 on 4-1/2 - Maxx Coating - 3,500 lbs # DE66YR is indeed two of the # DE89YR put together to make ordering for one axle easier. That said, I have no idea why we have the pricing the way it is and I will be bringing this up to our pricing team. We are always told that it's some kind of computery algorithm thingamajig (which I am too much of a caveman to understand) that causes this to happen, but this...

    We do have some options for replacing the Knott calipers and rotors on your Coyote Boat Trailer. We really do not have any info or specs on the Knott brand brakes, but since it is all for a 3,500 lb axle the sizing should be standard. Standard meaning the axle uses the standard 4-bolt brake flange (holes 2-7/8" apart on center), and the hub uses the # L68149 (1.378" inner diameter) inner bearing, and the # L44649 (1.063" inner diameter) outer bearing.

  • Is there an Interchangeable Hub for Mine that Had DB-42 Stamped on it? 3,500 Pound Axle.
    Hello Mike, Disc brakes are brand specific when it comes to parts, if you try to mix the parts the will NOT line up. What I am showing is that the DB-42 is an older UFP set-up that uses the standard 3,500 pound axle bearings Inner bearing: L68149 and Outer bearing: L44649. Since there is no longer a hub/rotor for the DB-42 you will need to get a whole new system.

    Hi Brian, If you have a boat trailer with a 7,000 lb single axle you wouldn't have 10 inch brakes, they would be larger as 10 inch brakes are for 3,500 lb axles. Since I'm not 100% sure what you have I can't directly answer your question, but I can tell you how to find the correct replacement. You will need to take apart your current 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...
