Features to know about

Upgrade to Confident, Controlled Stopping: Electric-Over-Hydraulic Power

Say goodbye to delayed or uneven braking. This DeeMaxx disc brake kit uses an electric-over-hydraulic actuator rated for 1,600 psi, giving instant response when your in-cab brake controller sends the signal. With a 12V DC motor drawing 18–24 amps at full pressure, it provides solid, consistent braking feel instead of the push-pull sensation of surge systems. The actuator even lets you brake while reversing down an incline for better control when maneuvering.

Built for Harsh Conditions: Maxx Coating and Drainage Design

Salt, water, and road grime can destroy unprotected brakes fast. The Maxx coating on the rotors, calipers, and brackets holds up through more than 1,000 hours of salt spray testing—outlasting typical zinc or Dacromet finishes. Each rotor also has drainage holes in the hat section so water clears out quickly after launch or rain. Together, they help keep the system free of corrosion and running smoothly year after year.

Keeps Cool Under Load: Vented Rotors and Kevlar Pads

Long grades and heavy loads won’t overheat these brakes. The vented one-piece hub-and-rotor assemblies move air through the core to shed heat fast, while Kevlar pads resist wear and dissipate heat evenly. The stainless steel piston stays responsive under pressure for smooth, fade-free stops every time. It’s durable, automotive-grade construction made to deliver consistent braking under tough towing conditions.

DIY Upgrade Made Simple: Complete Bolt-On Kit with Built-In Guidance

Everything needed for a full triple-axle conversion is in one box—six integral hub-rotors with pre-installed bearings, races, seals, caps, calipers, brackets, necessary hydraulic lines and fittings, plus a DOT/SAE-compliant rubber hose kit. Each caliper has laser-etched bleeding instructions right on the back so you don’t have to dig for a manual when it’s time for maintenance. With direct bolt fitment and clear labeling, installation and upkeep stay straightforward.

Engineered for Strength and Longevity: Heavy-Duty 7K Axle Rating

Each assembly is built for 7,000 lb axles with an 8 on 6-1/2" bolt pattern and 1/2" wheel bolts, fitting wheel sizes from 15" to 17-1/2". The sealed hub design keeps out moisture and debris while maintaining smooth rotation. Backed by a 7-year warranty on the brakes and a 2-year warranty on the actuator, this DeeMaxx kit delivers reliable stopping power and long service life across seasons of towing.

Video Transcript for DeeMaxx Disc Brakes | Expert Insights from the Manufacturer

Hello, neighbors, it's Brad here from etrailer. And today I'm at NATM. And this convention brings a lot of the vendors that we have at etrailer to a convention where we have their booths and their products set up. I had a chance to catch up with quite a few of them. So, let's take a look at their products a little bit up close and ask some of the questions to those vendors about their products. I'm here with Brandon from DeeMaxx and DeeMaxx offers a whole line of brake products, and we're gonna break these down.

Yeah. So, what is DeeMaxx as a company DeeMaxx, we are a light to medium-duty trailer disc brake manufacturer. We kind of have the whole assembly of the process now from the brake lines and fittings up to our actual brake parts themselves. Like, you see this rotor hub here, and the calipers all the way down to the actuators as well. So, here we have a disc brake assembly, caliper and rotor.

Let's break this down. What makes you guys stand out, you know, not only from a drum brake, but from a disc brake standpoint Yeah, absolutely. So, only thing we don't have on the table here that we do have on our backdrop and elsewhere in the booth, we've got the mounting brackets as well. So, we've got our slip-over rotor here. One of the big things that we, you know, that we we inchesre able to do at the start when DeeMaxx was created was Chuck wanted to put an emphasis on advantages over other disc brake manufacturers, not just having advantages over the drum brakes.

And one of the ways we did that in our rotor design is the holes in the hat. It's gonna promote the, like I said earlier, the better dissipation of heat, better draining and then more even plating on a coating. So, you've got a rotor that doesn't have the holes in the hat and you go to do the coating on it, you're gonna get that pocket of air in there, and you've got that pocket of air, you're gonna have to go back and redid that area or recoat that area. And it's not gonna be an easy coat. As far as calipers, you know, we carry everything for our brakes from 3.5K up to 16K axles.

The 7K and up, we're gonna have Kevlar pads in. That's kind of a new thing for us. From the end of 2023 beginning 2024 is the Kevlar pads. We really wanted to see our pads be able to grip a little bit more. For certain applications where the Kevlar may not be best, maybe going more with the stainless if you're in a marine industry. But the over-the-road guys, those utility guys, even the RVers that don't frequent the salt water communities, those guys, that the Kevlar pouch are just perfect for it. But best part about DeeMaxx is our seven-year warranty. We're not gonna discriminate based on the coating or type of product you've got. Whether you've got the Maxx, the stainless, everything's covered for seven years. So, we stand by our product in that, you know, the coating or the material shouldn't really waiver in the company's support for your product. Absolutely. And I've been able to install these on trailers and do the whole conversion. And I did my own break test, it's night and day. I think the guy that was towing it too, he was blown away. I mean, turning the game down by nearly 80% and getting this way better breaking even at that, it was really an eye-opener to me. Brandon Yeah. And you know, drum brakes, like you said, it's kind of an old technology and I love old hot rods, but if you have standard brakes on those, they're terrible for stopping. So, why would you do the same to your trailer We've come long way in technology. Yeah. Might as well keep yourself safe. Now, going back to pads, you mentioned Kevlar, is that gonna be for more long, like, longer lifespan, better bite What does Kevlar offer over a traditional pad So, the origination behind us going after wanting something that's gonna have that more bite to it, more resilience behind the material. We are very supportive of our military. We work hand in hand with every branch of the U.S. military all the way up to the guys out in outer space. And those guys we inchesre the ones that really came to us and said, "Hey, man, we're gonna need something that's gonna be beefier, it's gonna be able to stop, it's gonna meet these certain tests that the military has to meet, but these end users can't." And it's like, "Hey, you know, we've developed this Kevlar brake pad product and it's the U.S. military is using it." If it's good enough for them, I promise you it's good enough for the end user like you and me. Yeah. You know, it's interesting too as far as maintenance goes because many people with drum brakes, if you ask them, "Hey, are years in good condition" They're gonna go, "I don't know." Because most people aren't taking that off to take a look. And that's something with disc brakes, you can look at the pad and see where- Brandon Yup. You're at, and if you do need to change it. Yeah, you can. A lot of the drum brake guys as some of 'em say they've got the self adjusting ones. And it's like, if you're not getting in there and looking, are you willing to bet your family's safety, your work You know, these hot shot guys, are you willing to bet that that it's actually adjusting Probably not. So, you're gonna want to go in there and look at it yourself, check the adjustments. And that's when it goes down to the more and more maintenance on the drum break user versus the disc brake guy. They can take a peek in there, take a feel in there and be like, "All right, it's time to replace my pads." Now, if someone did wanna make the switch to disc brakes on their trailer camp or whatever it may be, what else would they need to get in order for that system to work We don't sell any, you know, full kits. We sell the actuators by itself. We sell the brake line kit by itself and our retail brake kit. You, guys, do a full thing, where y'all actually bundle those together and sell them as a complete system. So, if you knew what break kits you needed, what break line kits you needed, and say you know what actuator you needed, y'all have a kit for that, more than likely. Y'all have several kits of bundles, those all pieced together, which is super awesome for the neighbors. Oh, a huge thing to Brandon from DeeMaxx, taking the time to- Yeah. You know, really explain why disc brakes might be a great option. And I mean, these are this high-performance standard. These are awesome. So, thank you for your time. Yeah, absolutely, for your time. And appreciate you being here. Thank you guys for all your support. Thank you. Awesome.

Good product with straight forward installation. Only issues were that the kit included the wrong dust caps and several mismatched lock nuts for the backing plate mounting bolts. The proper parts were easily source from my local hardware store.

See what our Experts say about this DeeMaxx Trailer Brakes

  • What Kind of Brake Fluid is Recommended for DeeMaxx Disc Brakes?
    Hello Gene, For your DeeMaxx disc brakes # DE86AR, you'll want to use DOT 4 brake fluid. It’s the recommended type because it handles heat really well, which is important for trailer and heavy-duty braking systems like DeeMaxx. You’ll want to steer clear of DOT 3 and especially DOT 5! DOT 5 is silicone-based and just isn’t compatible with the components in your system. Are you making the swap over to disc brakes? What kind of trailer is this on?

  • Gap At Back Of Spindle And Shoulder After DeeMaxx Disc Brake Kit Installation
    Hey Caylan! Are you referring to the DeeMaxx Disc Brake Kit # DE86AR? Yes, this can be acceptable, but that gap would only be visible before the grease seal is installed. Once the hub is fully assembled, the grease seal covers the inner bearing so you wouldn’t be able to see any gap behind it. If you’re noticing this during a test fit, a small visible gap can be normal as long as the bearing is fully seated as far back as it will go. Since your bearing part numbers match the originals,...
