Swapping out old drum brakes for this DeeMaxx 13" disc setup gives you consistent, confident stopping. The one-piece hub-and-rotor assemblies reduce uneven wear and keep water and debris out. Ceramic pads and a stainless steel piston deliver fast, responsive braking, while the 2-1/2" piston diameter and 7,000-lb axle rating give plenty of control under load.
If you tow or launch in wet or salty conditions, rust is the enemy. This kit’s Maxx coating on the rotors, calipers, and brackets resists corrosion for over 1,000 hours in salt spray testing—far longer than zinc or Dacromet finishes. Drainage holes in the hat section let water escape quickly and keep internal surfaces clean, so your brakes stay protected season after season.
When braking on hills or hauling heavy loads, heat can kill performance. These vented rotors move air through the core to shed heat faster and prevent brake fade. The extra drainage holes also help moisture and heat move out efficiently, keeping braking smooth and predictable mile after mile.
Designed with the do-it-yourselfer in mind, this kit includes everything needed for one axle—two Maxx-coated hub-rotor assemblies with bearings, races, seals, caps, bolts, and lug nuts. The calipers feature laser-etched bleeding instructions right on the housing, so maintenance is straightforward without hunting for manuals. Bolt pattern is 8 on 6-1/2", wheel bolt diameter is 9/16", and it’s ready to use with a hydraulic actuator rated at 1,500 psi or higher (sold separately).
Every component here is designed for durability—cast iron hub-rotors, side-support mounting brackets that reduce bolt wear, and long-life ceramic pads. Rigorous SAE J2681 testing proved the same level of friction performance expected from automotive brakes. Backed by a 7-year warranty, this setup delivers dependable braking power trip after trip.

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?
