  • Low Maintenance: Fewer moving parts than drum brakes mean less upkeep and quick pad changes when needed.

Features to know about

Upgrade Old or Failing Brakes: Stainless Steel Disc Kit for Smooth, Confident Stopping

If your trailer’s braking is sluggish or uneven, this DeeMaxx disc brake kit with 13-1/8" slip-on rotors is a solid upgrade. It replaces worn or idler setups with stainless steel rotors, calipers, and brackets that deliver strong, consistent braking. Ceramic pads and a 2-1/2" stainless steel piston give fast, responsive power with a smooth feel every time you stop.

Built for Harsh Environments: Stainless Steel Construction Resists Corrosion

Saltwater launches, snow, and road salt can destroy standard brakes. These components are fully stainless steel—rotors, calipers, and brackets—so they’re rustproof and tough enough for coastal or winter use. Drainage holes in the hat section let water escape quickly and help prevent corrosion inside the rotor. The result is dependable performance season after season without the worry of rusted parts.

Keeps Cool Under Heavy Loads: Vented Rotors Prevent Fade and Pad Wear

Hauling heavy or driving long downhill grades can overheat brakes fast, but the vented rotor design here helps shed heat quickly. DeeMaxx adds drainage holes that boost ventilation even more, reducing brake fade and extending pad life. These rotors passed the rigorous SAE J2681 automotive brake test for friction performance—proof of how well they handle real-world stress.

DIY-Friendly Setup: Slip-On Rotors and Laser-Etched Bleeding Instructions

You don’t need special tools or a full teardown to install this kit. The slip-on rotors fit over standard idler hubs and use your existing wheel bolts, so there’s no need to replace the entire hub-and-rotor assembly. Each caliper has laser-etched instructions right on it for easy bleeding when it’s time for maintenance. The kit includes two slip-on rotors, calipers, and brackets to upgrade one axle.

Durable Design with Long Warranty: Built for 8,000 lb Axles

This kit is engineered for strength with an 8,000 lb axle capacity, 8 on 6-1/2" bolt pattern, 5/8" wheel bolts, and a 4-bolt brake flange configuration. High-quality automotive-grade materials ensure long service life, backed by a 7-year warranty for peace of mind every time you tow.

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.

Wow, the calipers, rotors and brackets are awesome.
Great price!

I'm sure the quality of these is good but I'm annoyed that there is no mounting hardware included. The enclosed instructions make multiple references to the "provided hardware" but there is none. So I spent $[XX] each on two brake kits and now I have to drive to town for hardware
