1. it goes dirty due to degradation, the more moisture it absorbs causes it to effectively look rusty !
2. action of cylinder being used will allow some fluid to exit/re-enter reservoir but only moving through transfer ports in the cylinder--not the whole system
3. if different grades of fluid, or even mixing synthetic they may not mix....better to replace wheel cylinder/caliper so that you can carry out a full change properly by doing all 4 corners.
