Dexter Axle Brake Actuators

Dexter Axle Brake Actuators: Electric-Over-Hydraulic Braking You Can Trust

When it comes to trailer braking technology, few names carry more weight than Dexter Axle. With over 60 years of engineering expertise serving utility, RV, marine, agricultural, and specialty trailer markets, Dexter has built a reputation as the go-to source for precision brake actuation. Their lineup of brake actuators represents the cutting edge of electric-over-hydraulic (E/H) trailer braking — a category where Dexter has invested heavily in design, materials, and safety innovation.

The DX Series Electric/Hydraulic Actuator

The cornerstone of Dexter's brake actuator lineup is the DX Series E/H Actuator, available in two pressure configurations to match your braking setup. The drum brake variant delivers up to 1,000 psi of hydraulic output, while the disc brake version ramps that up to 1,600 psi — both capable of handling single, tandem, and triple axle configurations without risk of starving the brakes for fluid. Brake fluid pressure is proportional to the electronic brake controller signal, meaning you get smooth, progressive stops that mirror exactly how much braking force you ask for.

The DX Series is built tough from the ground up. A lightweight, corrosion-resistant anodized aluminum housing features fins and venting to shed heat and moisture, while Goretite seals protect the internal electronics from the elements. Inside, solid-state electronics eliminate mechanical relays — improving durability and guarding against damage if wiring connections are made incorrectly. A self-priming pump reduces brake-bleeding time and prevents fluid from draining back into the reservoir when the unit is idle, keeping the system ready to perform on demand.

BrakeRite E/H Actuators: Flexibility for Every Application

For those seeking an even more installation-friendly option, Dexter offers the BRAKERITE® Electric/Hydraulic Actuator line. BrakeRite comes in two models designed to match either disc or drum brake setups. The standout option is the BrakeRite Plug & Play model, which simplifies field installation through a plug-in wiring harness — reducing setup time and minimizing wiring errors. A hard-wire standard BrakeRite EHB model is also available for those who prefer a direct-wired configuration. For heavy commercial applications, the BrakeRite Severe Duty variant is engineered for demanding use with weather-sealed, plug-in external control modules.

Why Electric-Over-Hydraulic Beats Traditional Surge Actuators

Unlike conventional surge brake actuators, Dexter's E/H actuators deliver proportional braking pressure that corresponds directly with the voltage output from your in-cab brake controller. This eliminates common surge brake problems: no brake drag going downhill, no "pushed by the trailer" sensation that can contribute to jackknife situations, and — critically — full braking capability when reversing the trailer. Drivers retain complete manual override capability from inside the tow vehicle, adding an important layer of active safety control.

All Dexter E/H actuators are backed by an industry-leading 2-year warranty and are compatible with most aftermarket and OEM-integrated electric brake controllers, reflecting Dexter's commitment to broad system interoperability across trailer types and tow vehicles.
