Features to know about

Upgrade From Drum to Disc: 13" Hub-and-Rotor Kit Delivers Reliable Braking

If your drum brakes are fading or uneven, this 13" DeeMaxx disc brake kit gives you stronger, smoother stopping. The 1-piece hub-and-rotor assemblies eliminate the gap where rust and runout can start, while ceramic brake pads keep braking consistent. The kit fits 8,000-lb axles with #42 spindles, uses 9/16" wheel bolts, and includes all bearings, races, seals, E-Z Lube caps, and stainless lug nuts for one axle.

Built for Salt and Water: Maxx Coating Resists Corrosion

Water and salted, winter roads can ruin unprotected brakes fast. The Maxx coating on these rotors, calipers, and brackets lasts more than 1,000 hours in salt spray testing—far beyond zinc or Dacromet finishes. It keeps moisture and rust from taking hold even after repeated launches or coastal towing, giving you long-term reliability in harsh environments.

Keeps Cool Under Load: Vented Rotors Prevent Fade and Wear

Steep grades and heavy loads push brakes hard. DeeMaxx vented hub-and-rotor assemblies move air through the core to dissipate heat quickly. Drainage holes in the hat section also help shed water and reduce internal corrosion. The result is cooler running brakes that hold performance over time and resist brake fade on long descents.

Simple Maintenance and Service: Smart Details Save Time

Disc pads are easy to swap because the calipers mount outside the hub—no springs or magnets to fuss with. Each caliper has laser-etched bleeding instructions right on the back, so you always have a guide when it’s time for maintenance. With fewer moving parts than drum brakes, this setup takes less upkeep to stay in top shape.

Long-Term Strength You Can Count On: Proven Design and Warranty

Automotive-grade materials and a side-support caliper bracket design put the load on the bracket instead of the bolts—reducing wear and keeping everything tight. These brakes passed the SAE J2681 automotive brake test for friction performance and come backed by a 7-year warranty for dependable service mile after mile.

See what our Experts say about this DeeMaxx Trailer Brakes

  • Replacement Trailer Disc Brakes for an Alliance RV with 8K Axles
    Hey Wade, thanks for reaching out! To upgrade your 8K Dexter Axle to disc brakes, I recommend picking up the DeeMaxx Disc Brakes which comes with either 9/16" Studs # DE63AR or 5/8" Studs # DE93AR depending on what you're needing. I really like the DeeMaxx kits because they use a better coating than most other brake companies out there; they boast an impressive over 1,000 hours salt spray rating that I have yet to see another brand come close to matching. What do you think about these kits?

  • Disc Brakes for 16k Texas Pride Lowboy Trailer With 8k In House Axles
    Hi Cw; sorry for the delay on this. If you can tell me what kind of spindle you have on those axles, or just tell me the bearing and grease seal part numbers, I can find the right disc brakes for the trailer.

  • Recommended DeeMaxx Disc Brake Conversion Parts for a Trailer w/ 8,000 lbs Axles
    Welcome back Randy! There's no 8,000 lbs kits but I have all the parts you'll need to convert your trailer's 8,000 lbs axles to disc brakes. I have listed them below: DeeMaxx Disc Brakes - 13" Hub/Rotor - 8 on 6-1/2 item # DE93AR if you have 5/8" lug studs or item # DE63AR if you have 9/16" lug studs. These are sold as a pair of left and right assemblies so you'll need two sets for a tandem axle trailer. They work with 16" and larger wheels. DeeMaxx Alpha G1600 Electric Over Hydraulic...

  • Difference Between DeeMaxx Disc Brakes DE53AR and DE63AR
    Hey Vinh! The difference is in the axles they're designed for. The DeeMaxx Disc Brakes # DE53AR are designed for your standard 8k axle. The # DE63AR is specifically designed for the old ALKO 8k axles. Unless you have an ALKO axle on your trailer, you will want the # DE53AR. What kind of trailer do you have?

  • Can 2019 Grand Design Momentum 381M be Upgraded to 8K Suspension Parts in Stages
    Hey Kyle, good to hear from you again! You can definitely upgrade the suspension components on your 2019 Grand Design Momentum 381M in increments because the 7K and 8K brakes match enough that it can work out that way, you just need to make sure the bearings for your current brakes will match up with the 8K axles when you purchase them. We unfortunately don't carry any axles rated higher than 7K so you'll have to take the bearings numbers you currently have with you to your local RV dealership...

  • Disc Brakes for 2022 Vanleigh Beacon 41FLB
    Hey Dewayne! Since your 2022 Vanleigh Beacon 41FLB has 8k axles I recommend the DeeMaxx Disc Brakes # DE63AR. Are you converting from electric brakes? If so, you will also need a brake line kit # HS496-252, a breakaway kit # 3802308 (if you don't already have one), and an electric over hydraulic actuator # HS381-8067.
