Features to know about

Upgrade Old Drum Brakes for Real Stopping Power: 13" Disc Kit Rated for 8,000-lb Axles

If your older drum brakes are worn or weak, this DeeMaxx kit delivers a big upgrade in control and confidence. The 13" 1-piece hub-and-rotor assemblies provide shorter, smoother stopping with consistent braking pressure. Each assembly includes inner (25580) and outer (02475) bearings, races, grease seals, caps, and 9/16" wheel bolts and stainless steel lug nuts. It’s a complete setup built to replace both brakes on a single axle rated at 8,000 lbs.

Built to Resist Rust and Corrosion: Maxx Coat Plus Stainless Steel Calipers

Saltwater and road salt can ruin ordinary brakes fast. The Maxx coat finish on these hub-rotors and brackets is corrosion-resistant and tested for over 1,000 hours of salt spray—far beyond zinc or Dacromet coatings. The stainless steel calipers won’t rust, and drainage holes in the hat section let water escape quickly to keep parts dry. It’s a marine-grade setup ideal for occasional saltwater use or harsh winter environments.

Runs Cooler and Lasts Longer: Vented Hub-Rotors Fight Brake Fade

When brakes retain heat, they lose performance. DeeMaxx vented rotors move air through the core and use extra drainage holes to shed heat faster than standard designs. That means less brake fade on long downhill stretches and more even pad wear over time. The result is cooler operation and dependable braking mile after mile.

Simplifies Maintenance: Laser-Etched Instructions and Minimal Upkeep

Disc brakes already save time compared to drums by eliminating springs, magnets, and constant adjustments. DeeMaxx goes further with laser-etched bleeding instructions right on each caliper—no manual required when it’s time for service. The stainless steel pistons respond quickly, ceramic pads deliver strong bite, and the overall design needs minimal maintenance while keeping performance consistent.

Built for Strength and Backed by Warranty: Complete Bolt-On Assemblies

Each cast-iron hub-rotor assembly is automotive-grade with a 4-bolt brake flange configuration and 8 on 6-1/2" bolt pattern for 16" and larger wheels. The caliper mounting bracket design supports weight on the bracket instead of the bolts to reduce wear. This complete kit comes ready to mount with all hardware included and carries a 7-year warranty for long-term reliability.

Video Transcript for Review of DeeMaxx Trailer Brakes - Hub and Rotor Disc Brake Kit - DE55AR

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at the DeeMaxx 13 inch hub and rotor assembly kit with the eight on six and a half inch bolt pattern, a 9/16 inch wheel studs for 8,000 pound axles. And this kit has a max coating and a stainless steel coating on the calipers. Now this will let you upgrade your trailer from drum to disc brakes for superior performance. It will include everything laid out here on the table, and we're gonna go through all the pieces here. And I'll start with the hub and rotor assemblies.

This will offer two max coated cast iron hub and rotor assemblies. They come with the bearing races already pre-installed in them. Comes with the two inner bearings, the two outer bearings, the two grease seals, the two easy low, easy lube grease caps that'll tap into the end of the hub right there. And if you notice the lug nuts are included. There's total of 16 9/6 by 18 size lug nuts.

And we mentioned the calipers will be a stainless steel caliper. Comes with the brake pads installed, the installation bolts included, and then the max coated caliper mounting brackets that the calipers will attach to two of those. Now this kit will require a hydraulic brake actuator that's rated at 1,500 psi or above and brake lines to activate your brakes. Those items we do sell separately. Now the hub and rotor assembly, they are a one piece design that will reduce the chance of uneven rotor wear.

The vented design, if you can see the vents all the way around the edge here, this vented design will dissipate heat faster to prevent premature brake pad wear. And also, if you notice in the hat section of this hub and rotor, you'll see these holes also. These are drainage holes that allow water to drain easily to help further minimize corrosion. Now this is excellent for occasional use in salt water area or areas with lots of snow slush and road salt. We mentioned the corrosion resistant max coat finishes on the hub and rotors on the caliper mounting brackets.

And on the calipers, they're stainless steel finish. Now the max coating that's on the rotors and the brackets, they do have a salt spray rating of over 1,000 hours. Now this will offer dramatically shorter stopping distances and smooth control braking. Now I also wanted to try to show you the brake pads, which are included on the calipers. You can see them installed there. They are ceramic brake pads to increase your stopping power. And then the piston is a stainless steel piston that is on the inside that activates those pads. It's a two and a quarter inch diameter stainless steel piston that'll provide fast responsive braking. Now this kit does require minimal maintenance, saving you time and money. And what's even nice about this, if you look on the outside of the caliper, you'll see some laser etching. Those are laser etched instructions that'll give take the guesswork out of installing the calipers and bleeding the brakes. Now this kit does fit the Alko 8,000 pound axles with the number 42 spindle. The wheel size that'll fit on these is 16 inches and larger. A bolt pattern is eight on six and a half inches, wheel stud diameter of 9/16 of an inch. Now the rotor diameter is 13 inches. And last thing I wanna show you is on your brake caliper mounting brackets, you'll notice has the four holes. So when you go to install this on your axle, this will bolt to a four bolt brake flange configuration on your axle. But that should do it for our look at the DeeMaxx 13 inch hub and rotor assembly kit, eight on six and a half inch bolt pattern with the 9/16 inch wheel studs for 8,000 pound axles.
