Same Color Brake Fluid Change

[OscarAH1W]

All,

 

Since the Feds have determined (in their infinite wisdom) that blue brake fluid makes it too hard to ensure one doesn't put Washer Fluid in the Brake Reservoir or vice-versa, what is a good way to ensure brake fluid is fully replaced when it is the same color?  Can you go by volume of fluid pushed out of the caliper?  Is there a way to dye the gold fluid without messing up the boiling point?

 

Thanks for the help; I have blue in the car now and one can of blue left so I have 2 changes worth, but my friends who I help regularly are stuck...

Actually, all you need is some clean clear plastic tubing and a small, but very bright flashlight.  The old amber fluid will have a slight discoloration to it from use; when the fresh fluid appears in the tubing back lit by a bright light, you will see it change.  We do it this way every day.
