Tandem-axle trailers put a lot of demand on your brakes, especially when you're towing heavy machinery at highway speeds. This DeeMaxx kit replaces drum brakes with hydraulic disc brakes for more consistent stopping power during long tows.
This version of the kit is built around 7,000 lb axles with larger 13-1/8" integral hub-and-rotor assemblies. The vented rotor design and built-in drainage help manage heat and shed moisture, while ceramic pads and a stainless steel piston provide smooth, consistent braking. If you are towing heavier equipment or larger trailers, the added rotor mass and axle rating give you more braking confidence.
The Maxx coating on the hub-rotor, caliper, and bracket is rated for over 1,000 hours in salt spray testing. Combined with rotor drainage holes and a 1-piece hub-and-rotor design, this helps reduce rust, contamination, and uneven wear, especially for boat trailers or winter towing.
The DeeMaxx Alpha G1600 actuator converts your in-cab brake controller signal into hydraulic pressure up to 1,600 psi. It reaches 1,000 psi in just 3/16 of a second for quick response. The extruded aluminum housing helps manage heat, and the sealed reservoir reduces contamination risk. A 360-degree brake line fitting allows flexible mounting.
The included tandem-axle hydraulic brake line kit features DOT- and SAE-compliant rubber hoses that are easier to route than rigid steel lines. Brass tee and cross fittings, clamps, and mounting hardware are included to secure the system cleanly to your trailer frame.
Disc brakes eliminate many of the springs and internal parts found in drum systems. The 1-piece hub-and-rotor design reduces the risk of trapped moisture causing uneven wear, and laser-etched bleeding instructions on the caliper make future service more straightforward.

Hi, everyone. Steve here with etrailer. Today we're taking a look at the DMAX Disc Display Kit with the Actuator for Tandem Axle Trailers. This is gonna feature a 13 inch hub and rotor assembly with an eight on six and a half inch lug pattern. And these are gonna be rated or 7,000 pound capacity axle. Folks, you're obviously gonna get a lot more what you see here on the table.
You're gonna get the four hub rotor assemblies with all the brackets that you need, brake line hoses, the actuator, all the inter races, outer races, bearings, et cetera, grease caps. Everything you need is gonna come in the kit. So looking at the rotor hub assembly together, it's gonna be great for water and winter towing. You've got slots all the way around here to help water drain. And also more importantly, to help it cool down as it's getting hot, you know, as it's breaking and whatnot, doing its job.
And of course you get the calipers with the brake pads and then that bracket here for the caliper, along with your bearings in and outer and grease seal, and of course the all important dust cap. We do include the rubber plug here. You can pop out way. If you have easily loop spindles, you can reach them easily with the grease zirk to do the maintenance. And of course, you're gonna get the powerful electrical over hydraulic actuator.
This is gonna give you fast response, giving you confident braking. And all the brake lines here are flexible. They are DOT rated and approved, making that installation a lot easier, smoother, and again, that flexible hose gives you an easier flexible time as far as the install. Now that being said, you don't wanna tackle the install yourself, no problem. We're affiliated with lots of different dealers and installers across the country.
You can reach out to us or use our dealer locator tool at etrailer.com by simply entering your zip code, and we can help find someone local to you to do that install as well. Again, an eight on six and a half inch bolt pattern. Again, common 7,000 pound axle setups is what that's rated for. Rotors again, 13 and technically 13 and one eighth inch wide. That's our quick look together at this DMAX Disc Brake Kit with Actuator for Tandem Axle Trailers. I'm Steven, thanks for watching.

That doesn't looks good at all, Bob. If you run into any issues before or after install, please let me know and I can help.

The best upgrade that I could’ve made to my fifth wheel was to get rid of those drum brakes and converted over to electric over hydraulic

Glad to hear they are working better than your previous brakes, Jerry! Disc is definitely the way to go. ^___^ I will let Ashley know they are much better as well! What's the next trip you have planned to really test them out?
