I used a turkey baster and sucked most of the fluid out of the
hydraulic reservoir, then removed the screen, sprayed it with brake

The light now goes off almost immediately.
In retrospect, I should have removed and cleaned the banjo bolt
screen on the high pressure hose to the bomb and cleaned that too...
