Tandem-axle trailers put a lot of demand on your brakes, especially when you're towing heavy loads at highway speeds. This DeeMaxx kit replaces drum brakes with hydraulic disc brakes for more consistent stopping power during long tows.
Drum brakes can fade under heat and require regular adjustment. This kit replaces them with DeeMaxx 1-piece hub-and-rotor assemblies designed for 3,500 lb axles. The vented rotor and drainage holes help shed heat and moisture, while ceramic pads and a stainless steel piston provide smooth, consistent stopping power. The result is more controlled braking and shorter stopping distances, especially when towing at highway speeds.
Launching in fresh water, or towing through winter road salt, exposes your brakes to corrosion. The Maxx coating on the hub-rotor, caliper, and bracket is rated for over 1,000 hours in salt spray testing. Combined with built-in rotor drainage, this helps reduce rust and extend component life compared to standard plated assemblies.
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 fluid reservoir reduces contamination risk. A 360-degree brake line fitting allows flexible mounting on the trailer frame or inside a compartment.
The included 20-foot hydraulic brake line kit is designed for tandem-axle trailers with disc brakes. DOT- and SAE-compliant rubber hoses are easier to route than rigid steel lines and work well with torsion axles or foldaway tongues. Brass tee and cross fittings, loom clamps, and mounting hardware help you secure the system cleanly to your trailer frame.
Disc brakes eliminate many of the springs and internal components found in drum systems. The 1-piece hub-and-rotor design reduces the risk of uneven wear from trapped moisture, and laser-etched bleeding instructions on the caliper make future service straightforward. Fewer wearable parts means less adjustment and more time towing.

Hi, everyone. Steve here with etrailer. Today we're taking a look at the DeeMaxx disc brake kit with included actuator for a tandem axle trailer. So folks, this is gonna be a complete disc brake upgrade kit. You can convert your tandem three and a half thousand pound axles from drum to disc hydraulic brakes. So obviously what I got here on the table is not enough to do that full kit.
I do wanna throw an image up on the screen of what you're gonna get. You're gonna get all four assemblies of those disc brake with the included rotors, the calipers, caliper brackets, and of course, the hydraulic actuator, with all your rubber brake lines and all your fittings included. So again, I just have one set here on the table as far as the rotor and hub and everything. And again, this features an inner 68149 bearing and an outer 44649 bearing. So the wheel bolts are half inch, and the lug pattern is a five on four and a half inch bolt pattern.
Make sure you're measuring your bolt pattern. There are a couple of options out there. You wanna make sure this matches up to what you are doing. And this rotor is gonna measure 10 and 3/16 inches overall in diameter. Now, another great thing about this kit is it's gonna be corrosion-resistant.
It has what's called their Maxx coating. It has a salt spray rating of over 1000 hours, making these perfect for marine and winter towing. The actuator, it features a 1600 PSI electric over hydraulic actuator. So you're gonna get super fast pressure response, giving you confident braking. And of course all your brake line hoses and everything are flexible.
They have some rubber caps on them right now just for protecting them for shipping and whatnot and packaging, I left them on there. But these are gonna do great. They're flexible so you don't have to worry about things breaking on you. You have more flexibility to route them. And of course the grease cap here, it's gonna be great for those EZ-Lube spindles that have that grease zerk on them. You can simply remove the rubber plug and grease up your spindles, the bearings, and everything internally with ease. And of course, again, all the hardware to mount it, the nuts, bolts, the brake line attachments, and all the anchors and whatnot for hanging them in line. Well folks, I think that's gonna wrap up our quick look together at this DeeMaxx disc brake kit, again, with included actuator for tandem axle trailers. I'm Steve with etrailer.

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?
