Product Description
The Hydrastar HBA16 1600 PSI Electric Over Hydraulic (EOH) Brake Actuator is a premium trailer braking solution engineered for trailers fitted with compatible hydraulic disc brake systems. Designed to deliver rapid, proportional braking response, the MHBA16 converts the signal from a compatible in-car proportional brake controller into powerful hydraulic braking pressure, providing smooth, confident stopping performance.
With a maximum hydraulic output of 1600 PSI, the MHBA16 is the recommended Hydrastar actuator for most hydraulic disc brake applications. Its sealed aluminium housing protects the internal electronics from moisture, dust and corrosion, making it an excellent choice for demanding Australian towing conditions, including marine environments.
This listing is for the Hydrastar HBA16 actuator only. Breakaway battery kits, switches, mounting hardware, hydraulic brake lines and other installation components are sold separately.
