Switching from drum to disc brakes makes a huge difference in stopping power and control. This DeeMaxx 12" disc brake kit replaces your old hubs with a one-piece hub-and-rotor assembly rated for 6,000-lb axles and a 6 on 5-1/2" bolt pattern. The ceramic brake pads and stainless steel piston deliver fast, smooth, and reliable braking. With fewer moving parts than drums, maintenance is minimal and pad changes are quick.
If rust has been eating away at your old brakes, the Maxx coating on this kit solves that problem. The rotors, calipers, and brackets all carry a protective Maxx coat finish that withstands more than 1,000 hours of salt spray—three times longer than Dacromet or zinc. Drain holes in the hat section let water escape easily to keep internal parts dry. It’s a solid choice for trailers that see fresh or brackish water or winter road salt.
Long grades and heavy loads can build heat fast, but these vented rotors shed it quickly. The combination of conventional venting and DeeMaxx’s unique drainage holes moves air through the rotor to prevent fade and premature pad wear. Cooler operation means steady braking performance when you need it most.
Everything you need comes in the box—hub-rotor assemblies pre-loaded with bearings, races, seals, caps, wheel bolts, and lug nuts—so installation is straightforward. The calipers have laser-etched bleeding instructions right on the housing to make setup and maintenance simple. All you’ll need to complete the system is a hydraulic brake actuator rated at 1,500 psi or above (sold separately).
Each kit includes two Maxx coat cast iron hub-rotor assemblies built with automotive-grade materials for long service life. With precision components—inner bearing 25580, outer bearing 15123, races 25520/15245, grease seal GS-2125DL—and a 7-year warranty, these brakes are made to deliver dependable performance mile after mile.

item looks to be excellent quality.!
Great products from great people with great prices
Product seems high quality, well built and customer service was also excellent.
WOrks very good. Fit on a 15" rim were not good. The site said any 15, 16 or larger. The calibers drag on the inside of rims. I had to choose to go larger size rims but did not want to go larger because the hight I was at lauching boat now. Called tech support, they worked wirh manufacture and was told to grind dowm edge or caliber. It has extra metal from mold at factory. I did about 1/4 inch end to end and all is good with about 1/8 clearaance now.
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.
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.
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.
Still have not road tested them, but the ease of installation was great. All 4 wheels swapped out in one day.
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:-)
