When your trailer is equipped with Dexter's DX Series™ Electrically Controlled Hydraulic Brake Actuation Device, you can be assured that years of engineering expertise, precision design work and every tap and jolt of the brake pedal. It's braking you can depend on.


DEXTER Electro/Hydraulic brake actuator is compatible with all vehicle electric connectors and works with most in-cab controllers. Electro/Hydraulic brake actuator provides 1000-1600 psi of pressure for 1-3 axles equipped with drum/disc brakes. Brake fluid pressure is proportional to the electronic brake controller signal.


Electric-hydraulic brake actuator works with your brake controller (sold separately) to activate your trailer's drum brakes. Vented housing releases heat and moisture. Enhanced wiring protection safeguards internal electronics. Sealed, anodized aluminum housing provides a weather tight seal.


When it comes to your trailer's braking system, demand better. Demand Dexter.
