The DeeMaxx Difference

Close-up image of DeeMaxx disc brake installation

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 rotor to provide even more ventilation than other brands. Combining these holes with the conventional venting design 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.


disc brake with signs of heavy rust and corrosion

The Maxx coating on the rotors, calipers, and brackets in this brake 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 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.


side-by-side comparison of an electric drum brake and a hydraulic disc brake

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.


close-up image of DeeMaxx disc brake caliper parts

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.


This particular kit can save you time and money over other disc brakes on the market as well. A slip-on rotor may be easier to install initially, but water can find its way between the rotor and your existing hub, causing uneven rotor wear or runout. With a 1-piece hub-and-rotor assembly, water and debris can't get in to cause any corrosion or contamination.

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.


Determining the Bolt Pattern

If you want to remount your existing wheels after installing these brakes, you'll need a kit that offers the same bolt pattern. To determine the bolt pattern, count the number of bolt holes (or lug nuts) on your trailer's wheel. This will give you the first number in the pattern. To find the second number, just measure the distance between a bolt hole and the bolt hole across from it.

For example, on wheels with an even number of bolt holes: 6 on 5-1/2" means 6 bolt holes with 5-1/2" from the center of 1 hole to the center of the hole across from it.


diagram showing how to measure odd bolt pattern

And with an odd number of bolt holes: 5 on 4-1/2" means 5 bolt holes with 4-1/2" from the center of 1 hole to the farthest edge of one of the 2 farthest bolt holes.

Video Transcript for Review of DeeMaxx Trailer Brakes - Hub and Rotor Disc Brake Kit - DE63AR

Hello, everybody. This is Jeff at etrailer.com. Today we're gonna take a look at the DeeMaxx 13 inch Hub and Rotor Assembly Kit with the eight on six and a half inch bolt pattern, the nine 16th inch studs for 8,000 pound axles, and it has a Max coating finish on this. Now this kit will let you upgrade your trailer from drum to disk brakes for superior performance. It will include everything laid out here on the table. It'll include the two Max coat cast iron hub rotor assemblies, and it even has the pre-installed bearing races in them.

Comes with the two inner bearings, the two outer bearings, the two grease seals, the two EZ lube grease caps. The lug nuts are included, you can see, a total of 16 nine 16ths by 18 lug nuts. And then the calipers are included. They are a Max coated caliper with brake pads and installation bolts. And over here are the Max coated caliper mounting brackets.

Now this kit will require a hydraulic brake actuator that's rated at 1500 PSI or above, and brake lines to activate your brakes. Those items we do sell separately on our website. Now the hub and rotor assembly we talked about, it's a one piece hub and rotor assembly. This will reduce the chance of uneven rotor wear. If you look on the side here, it's a vented design.

They have the vents that go all the way around. This will dissipate heat faster to prevent premature brake pad wear. And also, if you look on the hat section right here of the hub and rotor assembly, they have the drainage holes in here. And this will allow water to drain easily, further minimizing any corrosion. Now this is great for towing and launching your boat in either fresh or brackish type water.

The corrosion resistant Max coating that's on the hub and rotors, the calipers, and the caliber brackets will have a salt spray rating of over a thousand hours. This will offer dramatically shorter stopping distances and a lot smoother controlled braking. Now I did want to show you in the calipers, they do come with the ceramic brake pads to increase the stopping power. And the piston in here, on the inside, is a stainless steel two and a quarter inch diameter piston, which will provide fast, responsive braking. And the other nice thing about it, it requires minimal maintenance, saving time and money. And one of the nice features on this, if you look at the outside of the caliper, they actually laser etch instructions on the caliper to take any guesswork out of installing and bleeding the brakes. Now this is designed to fit the AL-KO 8,000 pound axles with the number 42 spindle. The wheel size that'll fit on these is 16 inches and larger. We mentioned the bolt pattern is eight on six and a half inches. Wheel bolt diameter of nine 16ths inch. Rotor diameter is 13 inches. And I wanted to show you on the caliper brackets, you can see they have the four holes in them, so they are designed to fit a four bolt brake flange configuration your axle. But that should do it for a look at the DeeMaxx 13 inch Hub and Rotor Assembly Kit with the eight on six and a half inch bolt pattern, the nine 16ths inch studs for 8,000 pound axles.

  • Replacement Trailer Disc Brakes for an Alliance RV with 8K Axles
    Hey Wade, thanks for reaching out! To upgrade your 8K Dexter Axle to disc brakes, I recommend picking up the DeeMaxx Disc Brakes which comes with either 9/16" Studs # DE63AR or 5/8" Studs # DE93AR depending on what you're needing. I really like the DeeMaxx kits because they use a better coating than most other brake companies out there; they boast an impressive over 1,000 hours salt spray rating that I have yet to see another brand come close to matching. What do you think about these kits?

  • Can 2019 Grand Design Momentum 381M be Upgraded to 8K Suspension Parts in Stages
    Hey Kyle, good to hear from you again! You can definitely upgrade the suspension components on your 2019 Grand Design Momentum 381M in increments because the 7K and 8K brakes match enough that it can work out that way, you just need to make sure the bearings for your current brakes will match up with the 8K axles when you purchase them. We unfortunately don't carry any axles rated higher than 7K so you'll have to take the bearings numbers you currently have with you to your local RV dealership...

  • Disc Brakes for 2022 Vanleigh Beacon 41FLB
    Hey Dewayne! Since your 2022 Vanleigh Beacon 41FLB has 8k axles I recommend the DeeMaxx Disc Brakes # DE63AR. Are you converting from electric brakes? If so, you will also need a brake line kit # HS496-252, a breakaway kit # 3802308 (if you don't already have one), and an electric over hydraulic actuator # HS381-8067.
