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.


Close-up image of DeeMaxx disc brake installation of brackets

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.


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.


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.


diagram showing how to measure even bolt pattern

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.

Best upgrade to our 5th wheel. I will do this to every trailer I ever own. The install was straight forward if you have some mechanical knowledge and experience.



by:

Excellent customer service. All of my questions were answered. All of parts arrived the very next day. Parts appear to be of high quality.



by:

Really surprised how quickly parts came. One box looked pretty rough, but all parts appear to be there. Will know more after install and put a few miles on the trailer.

That doesn't looks good at all, Bob. If you run into any issues before or after install, please let me know and I can help.

We had a rough start getting the right brakes for our Brinkley Z3100. However after ETrailer realized they made an error on the order they were right on top of it, doing everything they could do to make it right. Their people are great, kind, well informed in their products, and communicate very promptly. E Trailer will be my go to supplier for RV, and Trailer needs.
You will not be disapointed with their customer care!



by:

Just traveled 800 miles after installing the disc brakes. Stopping distance is half of what it was. So pleased!



by:

The first order I made was incorrect due to my mistake, but Amy took care of it had the correct items sent out with the wrong items returned. Everything was very smooth.

  • Disc Brake Conversion Kit for 2019 Keystone Montana 5th Wheel
    I can get the parts from that video but what I don't know 100% is the bolt size on that brake kit. Based on our own installation video I believe it is the 1/2".

  • Identifying Rubber Washer Piece That Came With DeeMaxx Disc Brake Kit DE68YR
    Hello Bob, thanks for getting in touch. I am looking at the DeeMaxx Disc Brake Kit # DE68YR right now and I am not seeing anything included with this kit I would describe as a black rubber washer. Could it be one if the rubber rings fell out of the caliper somehow? Without looking at the piece it is hard to say. If you want to email me a picture of this rubber washer I am happy to take a look and I should be able to shed more light. My email is [email protected].

  • Parts Needed To Convert To Electric-Over-Hydraulic Disc Brakes On A 2024 Brinkley Z3100
    Hi Ray, To switch from electric to electric-over-hydraulic disc brakes you'll need to check a few things first. The first thing to check is the axle tube for the ID tag that lists its capacity. Next you'll need to remove a hub and either check the bearings and grease seal for their part numbers or measure the spindle at points B, C, and D with a caliper # PTW80157. We'll also need to know the wheel bolt pattern so that we can make sure everything fits back into place so you aren't buying...

  • DeeMaxx Disc Brake Kit Recommendation for 7k Tandem Axles 9/16" Wheel Studs
    Hey James, we can help but we don't have the complete kit you are looking for as a single part number. For the slip on rotor brake kit you'd want the part # DE49YR. You'd need two of these since you have a tandem axle trailer. Then for the actuator you would need the part # DE77SR and then for the brake line kit part # DE57SR and you'd be set. If instead you were wanting hub/rotors that were integrated you'd want the part # DE68YR instead of the # DE49YR.
