I have an ES and not a Legacy, but the tip would be the same, I think.

I had good luck using a pressurized garden sprayer, rigging up tubing to the spray tube after discarding the spray tip itself,  and bleeding from the brake caliper fitting up and out the reservoir until air bubbles were gone.  Probably did it 3 times until I was happy with the result.  One man job too.

Hey,

Any tips / tricks on the best way to fill the brake system for the first time on a legacy ? (it does have a park brake value and stock brake reservoir with copilot brakes)

Thanks in advance
