If your current brakes are dragging or worn, the DeeMaxx Disc Brake Kit (DE42FR) gives a big boost in control and safety. The slip-on rotors fit right over standard idler hubs and use your existing wheel bolts, so there’s no need to change the hub-and-rotor assembly. Ceramic pads and a stainless steel piston deliver strong, responsive braking that feels smooth and consistent every time.
Braking systems take a beating in wet or salty environments. DeeMaxx’s Maxx coating on the rotors, calipers, and brackets holds up for more than 1,000 hours in salt spray tests—outlasting zinc and Dacromet finishes. Drainage holes in the rotor hat let water escape quickly, preventing trapped moisture and internal corrosion. This protection keeps your brakes performing their best in both fresh and brackish water.
Heat buildup causes brake fade and faster pad wear. DeeMaxx vented rotors move air through the rotor to shed heat fast, keeping braking performance consistent when towing heavy or on long grades. The extra drainage holes also help disperse both heat and moisture for cooler, longer-lasting operation.
This kit is built for easy upgrades. The rotors slip on over your existing hubs, the brackets bolt right up, and laser-etched instructions on the caliper make bleeding straightforward. Each kit includes everything needed to add disc brakes to one axle—two slip-on rotors, calipers, and mounting brackets—and requires a hydraulic actuator rated at 1,500 psi or higher (sold separately).
Designed for everyday dependability, this automotive-grade system fits 3,500-lb axles with a 5 on 4-1/2" bolt pattern and 1/2" wheel bolts. With its corrosion-resistant Maxx coating, durable construction, and a 7-year warranty, it’s made to deliver safe, smooth braking season after season.

Heavy duty mounting brackets and calipers. Very high quality.
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
An excellent job and taking care of a problem that I had on my original shipment very impressed. Well done.
DeeMaxx Disc Brake Kit - 10" Rotor - 5 on 4-1/2 - Maxx Coating - 3,500 lbs came fast and well packed. Thank you
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

As far as I can tell they are working fine. When you back up don’t forget to put in the manual lockout as the brakes kick in and you’ll be going nowhere. No problem installing and they still look great.
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..?

Hey Isaiah! Would you be able to send me a picture of what you're talking about via email?
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.
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.
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
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.
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
