Features to know about

Shorter Stops and Smoother Braking: 13" Disc Setup with Stainless Calipers

If your trailer’s braking feels uneven or sluggish, this DeeMaxx 13" disc kit is a major upgrade. The one-piece hub-and-rotor assemblies deliver short stopping distances and consistent braking, while the stainless steel calipers and ceramic pads provide strong, responsive performance with minimal maintenance. Built for 8,000-lb axles and #42 spindles, it’s a dependable system that keeps braking smooth and controlled.

Built to Beat Corrosion: Maxx Coat and Stainless Components

Saltwater, snow, and road salt take a toll on standard brakes fast. The Maxx coating on these hub-rotors and brackets has a salt spray rating over 1,000 hours—far outlasting zinc or Dacromet finishes. Add in stainless steel calipers and drainage holes in the hat section, and you get a setup that sheds water, resists rust, and holds up to harsh conditions.

Runs Cooler for Longer Life: Vented Hub-and-Rotor Design

Heavy loads generate heat that can cause brake fade or early wear. DeeMaxx’s vented rotors move air through the core to disperse heat quickly and maintain even performance. The integrated hub-and-rotor design eliminates gaps where water or debris could collect, reducing runout and uneven wear over time.

Easy DIY Upgrade: Complete Bolt-On Kit with Laser-Etched Instructions

Each part arrives ready to mount for straightforward installation. The patented caliper bolt-and-sleeve design keeps everything aligned, while the laser-etched bleeding instructions on the calipers save time during setup or maintenance. The kit includes assemblies for one axle—two hub-rotors with bearings, races, oil seals, caps, wheel bolts, and stainless lug nuts—so you have what you need right out of the box.

Proven Performance You Can Rely On: Tested to SAE J2681 Standards

DeeMaxx brakes aren’t just built tough—they’ve passed the demanding SAE J2681 automotive brake test for friction performance. Combined with automotive-grade construction and a 7-year warranty, this system delivers the confident braking power trusted by professionals who depend on it every day.

Video Transcript for Review of DeeMaxx Trailer Brakes - Hub and Rotor Disc Brake Kit - DE48AR

Hello, everybody. This is Jeff at etrailer.com. Today we're gonna take a look at the D-Max 13-inch threaded hub and rotor assembly kit with the 8 on 6.5 inch bolt pattern, the 9/16 inch diameter studs for 8,000 pound axles. And these have a Max coating and a stainless finish. Now, this kit here will let you upgrade your trailer from drum to disc brakes for superior performance. We mentioned the threaded hubs on it.

They're mostly used in oil bath axles, and this part. or this kit will include everything laid out here on the table. We'll start with the hub and rotors. It's two Max-coated cast iron threaded hub and rotor assemblies, and on the inside, they have the bearing races already pre-installed. Comes with the two inner bearings, the two outer bearings, the two oil seals, the two threaded oil caps that would thread into the outside of the hub right there.

And the lug nuts are included. You can see a total of 16 9/16 by 18 lug nuts, two stainless steel calipers with brake pads and bolts, and over here are two Max-coated caliper mounting brackets. Now, this kit does 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 separate on our website. Now, the hub and rotors, these are a one-piece hub and rotor assemblies, so they do reduce the chance of uneven rotor wear.

If I turn this here, you'll be able to see on the sides, has a vented design to it. That's to dissipate heat faster, prevent premature brake pad wear. And also on the hat section of the hub and rotor assembly, you'll see the holes. These are drainage holes in the hat section that allow the water to drain easily, further minimize any corrosion. Now, this kit is good for...

it's excellent for occasional use in salt water areas with a lot of snow slush or road salt. We mentioned the Max coat finish that's on the hub and rotors. It's also on the caliper mounting brackets. They have a salt spray rating of over a thousand hours. We mentioned the calipers themselves. They're stainless steel, they are rust-proof. This does offer dramatically shorter stopping distances and smooth controlled braking. Now, I did want to show you the brake pads. They're in the calipers already. Flip it over, you can see there are ceramic brake pads to increase the stopping power. And the piston that's on the inside that applies those brake pads, it's a stainless steel piston that's a 2.25 inch diameter. This will provide fast responsive braking. And this kit requires minimal maintenance, saving you time and money. Actually, if you even look on the outside of the caliper, they do laser-etched instructions on the caliper to take the guesswork out of installing the brakes and bleeding the brakes. Now, this kit does fit the Dexter 8,000 pound axles with the number 42 spindle. The wheel size that'll fit on this is 16 inches and larger. We mentioned the bolt pattern is 8 on 6.5 inches. Stud diameter is 9/16 of an inch. The rotor diameter itself is 13 inches. And if you look at the caliper mounting brackets right here, you'll notice the four holes in it. It is designed to fit a four-bolt brake flange configuration that's on your axle. But that should do it for a look at the D-Max 13 inch threaded hub and rotor assembly kit with the 8 on 6.5 inch bolt pattern, the 9/16 inch studs for 8,000 pound axles.
