This Hydrastar actuator gives you the feel of hydraulic disc brakes with the control of an electric system. It responds instantly to commands from your in-cab electric brake controller (sold separately), sending hydraulic pressure right when you press the pedal. The result is smooth, proportional braking that eliminates the jerky on-off feeling of a surge setup. With a maximum output of 1,600 psi, it delivers strong, consistent stopping power for single- or tandem-axle trailers rated up to 14,000 lbs.
If you’ve ever had your brakes drag going downhill or lock up when backing into a tight spot, this setup fixes that completely. The electric-over-hydraulic design applies braking pressure only when you command it, so there’s no interference while reversing or driving down grades. You can also use the manual override feature on your brake controller to engage trailer brakes without touching the tow vehicle brakes, adding extra safety when loading or controlling sway.
The actuator housing is made from extruded aluminum that stands up to weather and corrosion without rusting or pitting. A built-in bleeder lets you quickly flush air from your lines for easier maintenance. It’s compact at 11-3/4" long x 3" wide x 7-3/8" tall, so it fits neatly on the trailer frame and connects directly into the wiring and hydraulic brake lines. The actuator carries a 2-year warranty, while the included brake components are covered for 1 year.
Everything needed to connect your disc brakes comes in the kit: one 15' brake line, one 6' line, two 4-1/4' lines, four 18" male/male flex lines, brass fittings, flare nuts, hose clamps, and self-tapping screws. A standard breakaway kit is also included for runaway protection. For triple-axle trailers, simply add line kit 9579-01 (sold separately). Once installed, you get dependable hydraulic braking that’s fully adjustable from inside your cab—no more getting out of the vehicle to lock out brakes or fight with a surge coupler.
