Upgrade your trailer to hydraulic disc brakes with this slip-over disc brake kit for one axle. It includes a MAXX-coated rotor, caliper, and mounting bracket to begin a hydraulic disc brake upgrade or replace worn brake components.
If your trailer's current drum brakes are no longer meeting your expectations, this kit gives you the primary components needed to begin upgrading one trailer axle to hydraulic disc brakes. It includes a slip-over rotor, MAXX-coated caliper, and MAXX-coated mounting bracket, helping move your trailer toward a hydraulic disc brake setup while supporting consistent braking performance. You can complete the upgrade with a compatible hydraulic brake actuator, brake lines, and other required hydraulic brake components (sold separately).
Replacing major brake components can turn into a much larger project when hub assemblies have to come apart. The slip-over rotor installs over a compatible existing hub, reducing the amount of work involved during installation while making future rotor service more straightforward. It's a practical design that helps keep your trailer easier to maintain as brake service comes due.
Trailers spend plenty of time exposed to weather, making corrosion a common concern after a brake upgrade. This kit uses MAXX coating on the rotor, caliper, and mounting bracket to help resist corrosion while keeping the primary brake components protected during long-term trailer service. Your trailer stays equipped with corrosion-protected brake components that are ready for the next tow.

Hi, everyone. Steven here with etrailer. Let's take a look at our DeeMaxx disc brake kit. Folks, this is gonna feature two 10-7/8 inch diameter rotors and it's gonna be made for a 5 on 4-1/2 inch lug pattern. Now folks, this is rated for a 3,500 pound axle. This is a slip over disc brake kit.
It's gonna be the main components needed to equip one, one trailer axle with hydraulic disc brakes. So obviously, you need to have the coupler on your trailer that's set up for hydraulic brakes, but then you can do this kit to give you hydraulic disc brakes. Now, everything as far as the calipers, these are a MAXX coated rotor. They do feature stainless steel pads on the inside there. So that's gonna give you long lasting and great stopping power.
And you can see the front face of that caliper. The piston diameter in here is a 2-1/4 inch diameter piston. So lots of stopping power. And everything else as far as your mounting brackets, these are what's called a MAXX coating as well from DeeMaxx. So you won't have to worry about rust, corrosion, or anything like that anytime soon.
And then, of course, both rotors, again, 10-7/8 inch rotor diameter. And they do have the slots in them as well. That's gonna help dissipate heat and it's also gonna help drain out water and stuff as well if you're going into water and those kind of applications. So very great product here. This is a slip over rotor design that's gonna make the installation simple.
And remember, all this is compatible with your setup. Again, this is a 5 on 4-1/2 half inch lug pattern. The brake flange mount is a four lug brake flange configuration, and the wheel belt diameter on these holes is for a half inch stud. So typically, this again is on a 3,500 pound axle. It's about a 14 inch or larger wheel as well. Folks, that's gonna wrap up our quick look together. I'm Steven. Thanks for watching.
Ratings & Reviews
Heavy duty mounting brackets and calipers. Very high quality.
The package fit my boat trailer perfectly. Installation was fairly easy and I am ver pleased with the product. thanks
Great product great service
Direct bolt on for factory trailer. The zinc coating looks like it will hold up to salt water
The cap to the brake fluid broke in shipping wondering if u can send a new one
DeeMaxx Disc Brake Kit - 10" Rotor - 5 on 4-1/2 - Maxx Coating - 3,500 lbs came fast and well packed. Thank you
An excellent job and taking care of a problem that I had on my original shipment very impressed. Well done.
Ordering process went great!! Shipment arrived on schedule. Good experience overall
Owned the system for over a year and no rust so far. I can tell the difference in the braking power.
Now just need to install
Great brake system, starting to rust now but I dunk my trailer in saltwater 4 times a week. Thank you George J and team for quick shipping and maintaining contact even a full year after initial sale. Will be using etrailer for future purchases!
They do not come with the mounting bolts to mount the idlers to the rotors is not included, the cost is about $10 per pair. Surprised they are not included, you would think it would be turn key with all of the parts and not have to go shopping for additional mounting bolts.
They have a good quality appearance. I couldn’t figure out what the 1” rubber grommet is for..?
Fast Shipping, the brake kit is super easy to install and is working great.
I have used these brakes on a boat trailer that is used in saltwater and so far it has been working with a small amount of corrosion. I think they will be good for another couple of years but will replace with stainless steel next time.
Great jod, well done.
The parts themselves are great, but the packaging was AWFUL. A big box with two rotors in it, with loose calipers and pads banging around inside with no additional packaging material to cushion these parts. Disappointed in the etrailer customer service team, who passed the blame to the shippers. I'm sorry, but the shippers didn't package these...etrailer did.
I wasn’t sure what parts would fit my trailer so I called for information. Ashley L directed me to the correct disk brake kit which turned out to be the exact fit. A relatively easy install and now I’m back on the road again.
I did not receive the 7/16 bolts that mount the caliper bracket to the axle I would not think I would have to use the old bolts there are six or seven years old to remount the bracket which I think would be absolutely absurd. That would be like put in a rocket into space and then when it comes back not rebuild the engine and send it back up why would you do that just saying. I feel that if I bought all of that Hardware meaning the brakes and whatnot but the bolts would be included
Works great, easy to install. One improvement would be to include the hardware (bolts, nuts, washers) I had to make two trips to the hardware store. I gladly would’ve paid to have the hardware shipped with the brake set.
Very nice, wish it came with coated mounting bolts also
Having electric brakes compared to Electric over Hydraulic disk brakes is no comparison at all. I’m so pleased with our DeeMaxx brakes that I can’t believe regular brakes are still allowed. They surely are not safer and they are not cost effective. I may need brake pads soon, but that’s a good thing all I have to change are the pads, not the total braking mechanism like you have to do with the conventional systems. Anyone thinking of converting, it’s worth every penny. I’m now considering independent suspension.
The other part of that purchase is etrailer, its expert support personnel and experience is second to none. Ms. Bay helped me make sure I got everything I needed. She is an outstanding representative of the larger company, also outstanding, etrailer. It will always be my first stop because of Ms Bay. Happy New Years to you all.
The calipers and brackets were original from 2018. Couldn’t get any more time out of them due to corrosion. I have coded the new ones with Cora seal and a few coats of zinc and rust oleum hoping I will be able to get a few more years out of them only time will tell.
Installed these on 2 customer trailers and they are nice kits but... the caliper bolts back out as the factory installed Loctite doesn't hold. Contacted DeeMaxx and they refused warranty even though they admit they have had numerous problems. Have not had issues since cleaning the blue Loctite off and installing red. (and replacing all the damaged components)
