Upgrade your trailer's braking system with this integral disc brake conversion kit for one wheel end. It includes the major braking and hub components needed for installation, including bearings, hardware, lug nuts, and a threaded cap.
If your trailer's current brakes are no longer delivering the stopping performance you want, this kit provides the major mechanical components needed to convert one trailer wheel end to hydraulic disc brakes. It includes an integral MAXX-coated hub and rotor, stainless steel caliper, mounting bracket, bearings, grease seal, threaded cap, lug nuts, and installation hardware, giving you a matched wheel-end assembly instead of sourcing the components individually. Complete the conversion with a compatible hydraulic brake actuator, brake lines, and other required hydraulic brake components (sold separately).
Building a hydraulic disc brake system one component at a time can lead to unnecessary parts matching and compatibility questions. This kit brings together the major mechanical components for one wheel end, with the hub, rotor, caliper, bearings, seal, cap, and installation hardware already matched to work together. It's a practical approach that simplifies the mechanical side of the conversion once your trailer's specifications have been confirmed.
Brake components spend their lives exposed beneath your trailer, making corrosion a constant concern after a brake upgrade. The integral hub and rotor use MAXX coating while the caliper is constructed from stainless steel, helping protect the major brake components from weather and road exposure. Your trailer stays equipped with corrosion-resistant brake components that are ready for the next tow.

Hi, everybody, Andy here with etrailer. Let's take a quick look at the zMax Max Coat Stainless Steel Disc Brake. Now this hydraulic disc brake conversion kit is gonna upgrade one wheel on your 3,500 pound trailer axle and give you stronger, more responsive braking, and all of the parts are needed for an easier installation. Now on your screen I am showing you that you can get this as a set of one as I have here. Maybe you just need to replace one wheel, one side of that trailer axle or maybe you need a set of two. So whichever one's going to work best for you, just take the appropriate part number that you see there on your screen, pop it in the search field of our website and that will take you through that quantity and you can add that to your order.
So compared to traditional drum brakes, disc brakes give you shorter stopping distances, smoother braking and better control, helping you tow with more confidence. Now this is built for long term durability, especially if your trailer is exposed to rain, road salt, or occasional salt water. The stainless steel calipers and max coated hub and rotor assembly is gonna resist corrosion far better than your standard finishes. With a 1,000 hour salt spray rating, that's more than three times the protection of Dacromet coatings. Drainage holes in the rotors also help water escape quickly so moisture doesn't sit inside and cause rust.
And then the vented one piece hub and rotor design is gonna run cooler than traditional brake setups helping to reduce heat build up for more consistent braking and longer component life. Maintenance is also going to be straightforward as well thanks to the laser etched brake bleeding instructions on each caliper. I think you can see that there. That's going to make servicing quicker and more accurate. See the brake pads here I've got an isolator in there to keep those brake pads in the caliper there.
But everything that you need to convert one wheel is included here, and you're going to get all of the bearings here and the bearing information is listed on this page, this product page, along with the seal information. Of course you're going to get the mounting bracket as well. And if you think you might need some help with installation on this product page, we have a link that's typically found underneath the photo section that will take you to our installer locator. Click that link and answer the questions that it has for you and that locator will find an installer in your area that etrailer has partnered with to help you with the install. Well again, my name's Andy.
Thank you for joining me.
Ratings & Reviews
I purchased this to replace what the OEM had on my trailer. Easy install, but had a probem with it after install. etrailer could not help determine how to fix the issue, but gave me the number to the manufacturer. After several calls to DeeMaxx with no reponse I figured it out.
They had answers to my questions. Shipping and delivery was quick.
Great company to buy from. Fast shippin g.
Product was as expected, good quality braking system, installed easily in about 1-2 hours per wheel. Shipping and ordering was quick and easy. Time will tell more after installing on my fresh water boat trailer.
Unfortunately, it did not clear my 15” wheels properly, as indicated in the product description. I found by adding a 1/4” wheel spacer, that was just enough to get the clearance needed to prevent the calipers from rubbing on my 15” rims. (I have also seen others say that they used a grinder to take about 1/4” off the caliper body to get them to clear). This is the only reason for 4/5 stars.
Emma was great at helping me purchase these parts. They arrived two days earlier than expected as well. Your videos are also very well done and full of great information. I have some painting and rust removal to do before reassembly but will send pix when complete. Thx again
Madison was a great help and knew exactly what I needed for my application. Parts came quick and were easy to install.
Have not installed yet but the kit appears well made. Hoping the pads hold up well.
Braking is 1000x better than the OEM drum brakes. I've had to turn the brake controller way down because I was locking up the tires on a 14,000 lb RV. Will plan on putting on other trailers that I plan on keeping for a long time.
Absolutely 100 percent positive!!!
ETRAILER.COM is the fastest customer service i have ever seen !
Great Job!!!!
They definitely made a huge difference for stopping no question about it
Parts look good. One problem is the caliper plate sticks out 3/16 inches farther which means you have to change the plate . Drilling out the old plate is a nightmare.
Fast Delivery, great tracking and all parts fixed perfectly.
Good product. Great service. Some damage occurred during shipping, but replacement parts were shipped free of charge.
Still have not road tested them, but the ease of installation was great. All 4 wheels swapped out in one day.
Just got them, but haven't installed yet. They look of very high quality. So far happy with the purchase I will do another review once installed and working.
Has been reliable for 1 year
Braking effect is much more pronounced that my previous disc brakes. Parts delivered quickly. Installed to replace Knott calipers which had been locking up frequently- these calipers and rotors show no signs of corrosion or loss of brake effect after a couple of uses in saltwater. I would highly recommend purchasing mounting hardware as these do not come with any- also note if you have tandem axels you need to have “T” line splitters as the brake line inlet is standard 3/16 (or 1/8 NPT if you remove the included 90° fitting)- the Y splitter that my previous calipers used through the lower bleed fitting were too big. Very satisfied so far; just need to see how they hold up over time.
Well Designed and build. I took some time to remove old set - it was rusted in place reel good. But install of the new set was very easy.
The improvement in braking is very significant i am controlling brakes with electric/hydraulic actuator and the system works just like brakes on the car - very precise and sensitive.
I have not had much time on the road with these but from day 1 it was obvious I made the right choice. The items came in packaging that I would rate at 4 stars as there were some concerns but nothing drastic. The install was straight forward and everything went together as intended. I like the better braking control with the new system that works much better than the old set. My trailer is 2019 and the rotors were badly rotted, the calipers worked but were hanging up but these are a total game changer. Brakes work great!
Awesome people to work with. Finding the right trailer parts isn't easy. Amy J has helped me out quite a few times. This is where I will get all of my parts.
Easy to install, Fit perfect, and Wow, stops you so much better than drum brakes!
Only thing that I could suggest is a better product description of exactly what’s in the box. I thought the bearings would be greased. (Nope) and the rotor and hub were 2 parts. (1 part). Other than that it was a great experience:-)
Fit perfectly on my EZ Loader Tandem Axle Trailer from 2008
The rotors are of average quality. Beware!!! The wheel studs are too short if you have aluminum alloy wheels. I had to change all 36. Installation is still in progress.
I bet they are nice, if shipped and re-sold by a competent company. Unfortunately, we're dealing with Etrailer here. Well... on this one, the last order I ever make with them. Crappy packaging means the rotors were free to make minced meat out of everything else inside the boxes. Due to life, it was a year before I was able to install them on the trailer. On top of it all, they decided it would be a great idea reward the hard-earned money I spent with them by spamming me, sending me unwanted unsolicited email until I threatened them with a lawsuit (CAN SPAM act).
I ended up visiting the local Tool store popular in the Northern and getting the parts to repair what Etrailer's incompetence in packing wrought.
