RE: FW: Re: [Chrysler300] Dot 4 mixed with Dot 5 Silicone

["Albert Vannice" <mavche@xxxxxxxxxxxx>]

     The question of distinguishing between DOT 3&4 glycol-based brake
fluid and DOT 5 silicone-based fluid is addressed in the Letters section
of the most recent issue of Auto Restorer.  Among the answers, perhaps
the most useful test is to remove some of the brake fluid and add a
little water.  Water is miscible with the glycol fluid and will mix
homogeneously, whereas it is immiscible and incompatible with the
silicone fluid and will sink to the bottom as small drops.

This is a good question.  Is there a way to tell the difference between
the two by putting some fluid on a towel and noting color or smell or
???
I have some cars with and some without, and now I am worried.
Thanks
