DeeMaxx Electric-Over-Hydraulic Actuator vs. Standard Surge Brake Actuators

With the DeeMaxx electric-over-hydraulic actuator, you'll get all the benefits of towing with an electric brake controller while using hydraulic brakes. Because this actuator will activate according to the settings you have chosen for your brake controller (sold separately), you will have more control over when and how the trailer brakes engage. Depending on the features of your brake controller, you may be able to control both the rate and intensity with which the trailer's brakes activate. You can also use the manual override on your brake controller, which allows you to engage the trailer brakes without having to apply the brakes in your vehicle. And perhaps most impressive, if you have a proportional brake controller, the brakes will be activated with an intensity that matches the braking speed and power of your rig.


This pump-and-motor-based system increases response time compared with surge-type actuators because the trailer brakes are triggered when you apply the brakes in the tow vehicle, as opposed to when the trailer pushes against the hitch ball. This not only gives you faster, more efficient braking, but it also eliminates the pushing sensation that occurs in setups that use standard surge brake actuators.


Electric-over-hydraulic actuators also allow you to activate the brakes when reversing down an incline, such as a boat ramp. Having the ability to brake in reverse gives you more control and prevents wear on your tow vehicle.


The DeeMaxx Difference

When brakes retain heat, they are more likely to experience brake fade, or loss of braking power. DeeMaxx addresses this problem by incorporating drainage holes in the hat section of each vented rotor to provide even more ventilation than other brands. Combining these holes with the conventional venting allows DeeMaxx brakes to disperse heat faster. They're also able to shed moisture better, leading to less internal corrosion. The result is cooler-running, longer-lasting brakes that offer consistent performance.


DeeMaxx brakes are the only trailer brakes to satisfactorily pass the high standards of the SAE J2681 brake test. This test is designed to evaluate the friction performance of automotive brakes, so DeeMaxx's passing grade should tell you just how well made these products are.

The patented design of the caliper mounting bolt and sleeve makes installation easier while ensuring that the sleeves stay in place within the caliper. In addition, the side-support design of the caliper mounting bracket puts all of the weight on the bracket instead of on the bolts. This reduces premature wear and extends the life of the bolts, further ensuring optimal performance.


DeeMaxx brakes perform well even in the most demanding environments, which is one of the many reasons why they are preferred by law enforcement agencies like the Texas State Patrol, U.S. Border Patrol, and U.S. Coast Guard.


Great for Campers and Boat Trailers

If you own a trailer, you know that rust and corrosion will eventually creep up no matter where you tow, especially if your equipment doesn't have any kind of protective coating or plating. But if you tow your camper or trailer in the Midwest during the winter, or if you ever launch your boat in brackish water, you'll need even more protection because of the salt you'll likely encounter.

The Maxx coating on the rotors, calipers, and brackets in this kit helps to ensure that DeeMaxx brakes don't end up looking like the one pictured above. It offers great corrosion protection, even with occasional use in freshwater and saltwater. Rust-resistant coatings are graded according to a salt spray rating. Basically, this rating shows the amount of time it takes for a material to show signs of corrosion when exposed to pure, continuous salt spray. Zinc plating typically begins to deteriorate after about 100 hours. Dacromet usually lasts for around 300 to 400 hours. DeeMaxx's Maxx coating lasts for more than 1,000 hours in the salt spray test.


The environment this test creates is much harsher than anything you'll ever experience in your journeys, but it provides a testament to how well DeeMaxx brakes resist rust and corrosion.


If you're living the salt life full-time or you live right on the coast, you'll probably want to invest in something that offers even more protection, like DeeMaxx kits that include stainless steel components for the ultimate in corrosion resistance.


Get a Safer, More Comfortable Ride

Say goodbye to the days of your truck being pushed and pulled by your trailer. Disc brakes provide a safer, more comfortable ride than drum brakes. They offer shorter stopping distances and deliver consistent braking - even at highway speeds. So, you won't have to worry about things crashing around in your trailer or camper next time you reach unexpected traffic on the highway or debate if you can actually stop before that yellow light turns red.


Save Time and Money

More and more people are switching their trailers over to disc brakes. Not only do disc brakes provide more controlled braking than drum brakes, but they also save you money by having fewer parts to maintain.

Unlike drum brakes, which have springs, magnets, and shoes that may need to be continually adjusted or replaced, disc brakes are virtually maintenance-free. There are no springs, cables, or other little components that you'll need to worry about failing.

The brake pads will naturally wear down, so eventually you'll have to replace them. But these pads are also way easier to replace than drum brake shoes. And the caliper - where the pads are housed - is located on the outside of the brake assembly. This means you just have to remove that one part to replace the brake pads rather than having to remove the entire assembly like you would with drum brakes.
instructions on how to bleed brakes laser etched into the back of a DeeMaxx disc brake caliper

DeeMaxx also has simple instructions for bleeding the brakes laser-etched on the back of the calipers. This convenient time saver means you'll always have the guidance you need on hand when the time comes for maintenance.


All-in-one Brake Replacement

DeeMaxx's integral brake kits combine the brake hub and rotor into a single cast iron piece. Unlike a slip-on assembly, the 1-piece setup makes installation easier because the hub and the rotor are combined . However, this can lead to some extra costs when replacing parts. If either the hub or the rotor needs to be replaced further down the road, the entire piece will be replaced.


Generally, we recommend replacing the brake pads and the rotors at the same time. When you mix and match new parts with used ones, you may save money in the short term, but this has been known to cause problems in the long term, such as uneven stopping power, brake bedding and hot spots. Always confirm that your rotors are in good condition with no rust, corrosion, or grooves before deciding to replace only the brake pad or only the rotor. And always replace parts on both sides of the same axle for balanced braking power.

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.

  • 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?
