Hello.
Bleeding is allowing fluid out of the caliper under pressure, to remove trapped air bubbles.
Flushing is the complete exchange of old fluid to new fluid.
When flushing, I remove the MAJORITY of fluid from the master cylinder with a syringe. I then refill to top and again remove the majority of the diluted fluid again with the syringe.
I then refill again, and then proceed to flush out the brakes by applying lever pressure, and opening the bleed screw at the caliper. (Having a 2nd person helps immensely here).
I will flush out 2 master cylinders full of fluid to ensure clean fresh fluid throughout the brake lines. As I stated, I use a rather long piece of clear hose attached to the bleed nipple so I can visually see both fluid condition and air bubbles.
