Bleeding Brake Lines During Installation of HydraStar Electric Over Hydraulic Actuator HBA16

Question:

I’m installing new calipers on my trailer and I don’t have a truck to use to bleed the brakes, can I use a hand vacuum pump instead? Also what type of brake fluid do I need? Thanks!

You can use a hand pump to bleed your trailer's brake lines or you can use 12V power input to the actuator from a charged 12V battery to power the actuator so you can clear the system of air. The HydraStar Electric Over Hydraulic Actuator # HBA16 uses either DOT 3 or DOT 4 brake fluid; you will need at least a quart to fill the actuator.

The written instructions for this item are linked for your reference along with both review and installation videos for the # HBA16.
