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.
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.
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.
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.
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. 
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.
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.
Kit is great, easy to install and fits good. I have 2 complaints though. Only one of the four disc kits came with the proper hardware to attach the caliper mount to the axle so I ended up just buying all Grade 8 hardware. My second complaint is the brake line that attaches the 4 way to the 3 way coupler. It's only 36" which is about 10" too short to span from one axle to the other. So I'm having a longer one made tomorrow. I feel like etrailer struggles a lot with packing and ironically the one box that was damaged and open was the one that actually had all the hardware. I can update about the performance when I get the new brake line made and the install finished.
Ordering process was a breeze, (thank you Paula). I provided the information, and she had the kit that I needed ready and shipped that evening. I was told it may take a week to get the kits, I received them in three days.
I had one question during installation about a piece that was in with the caliper and pads. After I called Paula, she did some checking (watched install video and talked to installers), they said the piece was something used for shipping. One side completed in less than two hours.
Installation was easy
It was just what my customer wanted to make his cross county trip
Great customer e
