If your old drum or surge brakes feel sluggish or uneven, this DeeMaxx kit makes a big difference. The electric-over-hydraulic actuator delivers instant response with no lag or push from the trailer. It activates the brakes through your in-cab controller, allowing full control over when and how much braking you get. With 1,600 psi maximum output pressure and Kevlar brake pads, you’ll feel smoother stops and more confident braking even under heavy loads.
Saltwater and road grime can destroy lesser brake assemblies fast. The Maxx coating on the rotors, calipers, and brackets lasts for more than 1,000 hours in salt spray testing—far beyond zinc or Dacromet finishes. Drainage holes in the hat section help water escape quickly and reduce internal corrosion. Whether you tow in fresh or brackish water, this coating helps keep your brakes looking and performing like new.
Steep grades and heavy trailers generate serious heat. DeeMaxx’s vented one-piece hub-and-rotor design moves air through the rotor to shed heat fast and cut down on fade and pad wear. The 13-1/8" rotors with stainless steel pistons keep braking consistent on long downhill runs. The integrated hub-and-rotor assembly also reduces uneven wear and makes installation straightforward.
Everything needed to convert one axle comes right in the box—hub-rotors with bearings, races, grease seals, grease caps, wheel bolts, lug nuts, fittings, clamps, and lines. The calipers even have laser-etched bleeding instructions so you can handle maintenance without digging for a manual. Most DIYers can tackle the full swap in a day using standard tools.
Each assembly is rated for 7,000-lb axles with 8 on 6-1/2" bolt pattern and 9/16" studs. Precision machining and automotive-grade materials deliver long-lasting strength you can rely on. The brakes carry a 7-year warranty, while the actuator is backed for 2 years—solid protection for a serious upgrade that’s built to last.

I installed this DeeMaxx disc brake setup on my Grand Design Momentum 397TH and man, what a difference!! Awesome quality parts and was straight forward to install. Any trailer going forward with have this setup on it! The whole experience with etrailer is second to none!
Works better than expected. Easy to install. Worked perfectly with stock 2022 brake controller. Solved all the trailer brake issues I was having.
