DeeMaxx Trailer Brakes - DE46AR

Highlights

  • Upgrade to Stronger Stopping: Electric-over-hydraulic actuator gives faster, smoother braking than surge types.
  • Resists Rust and Corrosion: Maxx coat finish on rotors, calipers, and brackets lasts over 1,000 salt-spray hours.
  • Fits Right On: Slip-on rotors mount over standard idler hubs—no need to replace hub-and-rotor assemblies.
  • Runs Cooler for Longer Life: Vented rotors with drainage holes shed heat and moisture to prevent brake fade.
  • Simpler Maintenance: External calipers and slip-on rotors make pad or rotor changes quick and clean.
  • Ready for Heavy Loads: Rated for tandem 7,000-lb axles with 13-1/8" rotors and 8 on 6-1/2" bolt pattern.

Features to know about

Upgrade Old or Weak Brakes: 13" Slip-On Rotors with Electric-Over-Hydraulic Control

If your trailer’s old brakes are dragging or not stopping like they should, this DeeMaxx kit gives you a major upgrade. The 13-1/8" slip-on rotors fit right over standard idler hubs and are held in place by your existing wheel bolts—no need to replace the whole hub-and-rotor assembly. The included Alpha G1600 actuator delivers up to 1,600 psi of hydraulic pressure from your in-cab brake controller for fast, smooth braking with no lag or surge. It’s a solid way to get automotive-grade control on a tandem-axle setup rated for 7,000 lbs per axle.

Handles Fresh and Brackish Water Use: Maxx-Coated Components Resist Corrosion

Towing or launching in salty or wet conditions can destroy unprotected parts fast. This kit’s Maxx coating on the rotors, calipers, and brackets has a salt-spray rating of over 1,000 hours—far beyond zinc or Dacromet coatings. Drainage holes in the rotor hat section help water escape and further cut down on rust. That means you spend more time towing and less time fighting corrosion.

Keeps Cool Under Heavy Loads: Vented Rotors and Kevlar Pads for Consistent Braking

Hauling weight or driving long grades builds heat that can fade brakes quickly. DeeMaxx vented rotors move air through the core to shed heat faster while Kevlar pads resist wear and dissipate heat evenly. The stainless steel piston delivers responsive braking even when hot, helping you maintain control during heavy stops or downhill runs.

Simplifies Install and Service: Complete Kit with Laser-Etched Bleed Instructions

DIYers will appreciate how straightforward this system is to set up. The slip-on rotors and bolt-on brackets make mounting easy, and the included rubber hydraulic lines meet DOT and SAE standards while being simpler to route than rigid steel lines. When it’s time for maintenance, laser-etched bleeding instructions on the back of each caliper mean you always have guidance on hand without needing to dig for a manual.

Built Tough for the Long Haul: Tested Performance and Long Warranty Coverage

DeeMaxx brakes are the only trailer brakes to pass the SAE J2681 automotive brake test for friction performance. The patented caliper bolt design keeps sleeves secure and reduces wear, while high-grade materials extend service life. The kit carries a 7-year warranty on the brakes and a 2-year warranty on the actuator—proof it’s built for dependable stopping season after season.

by:

All I can say is I wish I would have done this upgrade much sooner
Adding the disc break system really takes a lot of stress out of pulling a 14k camper
Much more confident in breaking



by:

I think this is a great upgrade to my 2006 5th wheel. They look good. They don't need constant adjustment and give a me more confidence in the brake system.

  • Recommended Disc Brake Conversion Kit for a 2019 Grand Design Solitude 373FB
    Hey David! The DeeMaxx Disc Brake Kit w/ Actuator for Tandem Axle Trailers item # DE46AR will work so long as you have idler hubs with a 8 on 6-1/2 lug nut pattern like item # DE46VR. These are slip on rotors so you're definitely going to need some idler hubs too. They are sold individually. It looks like your 2019 Grand Design Solitude 373FB has 7k axles with inner bearing item # 25580 and outer bearing item # 14125A. The DeeMaxx Trailer Idler Hub for 7,000-lb Axles - 8 on 6-1/2 item...

  • Idler Hubs and DeeMax Slip On Disc Brake Kit for 2019 Big Country 3360ss
    Hey Darrel, since you like the DeeMax 7k slip on kit the part number you'd need is the # DE46AR which comes with the slip on rotors and the needed actuator and lines. So for an idler hub what you'd want is the part # 8-231-50UC1 and you'd be set.

  • Disc Brakes for Sundowner Toy Hauler With Lippert Drum 2420801
    Hi James; Lippert wasn't able to identify the hub off of that number so I'm not 100% sure what bearing combination you have. It does look like it is an 8k hub with a 12" x 2" drum which isn't common. Another customer reported # 25580 inner and # 02475 outer bearings with some uncertainty but that would line up with your standard 8k bearing combination. Assuming that is correct, you can use the # KOD82FR if you're looking for a hub/rotor. If you want to use slip-on rotors you will need...

  • Disc Brake Kit for a 2017 Jayco Northpoint 387RDFS
    Awesome question, Jeff! Kit part # DE46AR would be a great kit for you 2017 Jayco Northpoint 387RDFS. It comes with everything you are needing if you didn't have any sort of disc brakes before and getting them added to your Jayco. I'm guessing your trailer currently has drum brakes right now?

  • Disc Brake Kit Fitment for a 2016 Forest River Salem 32ft RV
    Hey Shawn, thanks for reaching out! What is the weight capacity of the axles on your Forest River? If it isn't listed on a sticker near the tongue, you can find it on a sticker in the middle of the axle itself.

  • Disc Brake Kit that Fits 2022 Alliance Paradigm 310RL
    Hey Bill, yes the DeeMaxx Disc Brake Kit w/ Actuator for Tandem Axle Trailers # DE46AR is correct for your 2022 Alliance Paradigm 310RL that has 7k axles and comes with everything but idler hubs that the included rotors slip over. Do you have idler hubs already? If not, we have what you need for that with the part # AKIHUB-865-7-1-EZ-K which you'd need to order 4 of.

  • DeeMax Disc Brake Kit that Fits 2020 Keystone Montana 3791RD
    Hey Jeffrey, the DeeMaxx Disc Brake Kit w/ Actuator for Tandem Axle Trailers # DE46AR will work on your 2020 Montana 3791RD that currently has 12 inch brake assemblies but since this is a slip on kit without idler hubs you would need to get those as well like with the part # AKIHUB-865-7-1-EZ-K. You'd need a quantity of 4 of these hubs. How did you like the braking performance of the drum brakes you have currently?

    Hey, Robert! Happy to help you out.

If you don't need the actuator you can get kit part # DE53YR. This is a per axle...

  • Do DeeMax Slip On Disc Brake Kits Work as Well as Hub/Rotor Kits
    Hey Darrel, yes the DeeMaxx slip on disc brake kits like the part # DE46AR perform just as well as the kits that have the hubs integrated with the rotor. The difference is just a preference. Some prefer slip on as it allows you to more easily replace a damaged rotor in the future whereas others prefer a kit that doesn't require sourcing an idler hub as well. For what it's worth cars have slip on rotors basically in all applications and they work great there.

  • Does the DeeMaxx Disc Brake Actuator Work w/ the Factory Brake Controller on a 2022 GMC Sierra?
    Yes, it will Charles! The actuator included with the DeeMaxx Disc Brake Kit w/ Actuator for Tandem Axle Trailers item # DE46AR is indeed compatible with the factory brake controller included in the 2022 GMC Sierra 2500. You'll just want to make sure you have it on the EOH setting. If you have any additional questions, go ahead and click on the box where it says Reply to Jerred H and I'll be happy to answer them.

  • Parts Needed For Disc Brake Conversion On 2016 Forest River Surveyor 245BHS
    Hello Keith, thanks for reaching out. I can definitely help you with a disc brake conversion. You should be able to stick with the 6 on 5-1/2" wheels. This is the standard 6 lug pattern so it is very common. I can recommend parts for you, but first I will need a bit more info on your trailer. Specifically I will need to know your axle weight capacity, and bearing sizes. The best way to find this out will be to pull a hub and remove the bearings. Each bearing will have a number stamped...
