With the Hydrastar line of hydraulic trailer brake actuators you get the fastest response time for shorter stopping distance. In emergency situations, and in your day to day towing, you can control those precious fractions of a second that matter when it comes to stopping your trailer. Hydrastar hydraulic fluid compatible trailer brake actuators utilize the same hydraulic fluid commonly found in agriculture equipment and implements.

  • The vented model allows the release of moisture, pressure, and heat from inside the housing unit, thus further protecting the internal components.
  • The Expanded Reservoir model allows for additional fluid capacity for large trailer and brake configurations.
