Hydrastar Hydraulic Electric Brake Gen 7 Actuator

The Hydrastar hydraulic electric brake actuator suits tandem boat trailers up to 4500kg.

Tekonsha iPrimus, P2, P3 and the latest Redarc brake controllers are suitable to control this actuator.

An electric over-hydraulic actuator requires an electric brake controller to send a signal to work a hydraulic pump actuator. Hydraulic brakes are used on boat trailers over 2000kg.

After purchase, the Hydrastar brake actuator manual and wiring diagram will be provided in a download link.
