Used DOT 4

["John Speiser" <jspeiser@erols.com>]

Graet article, Bob, on driving safety in the current British Marque news . .
. good suggestion about changing the DOT 4 brake fluid every 2 or 3 years .
. . I hope listers know to never toss it in with their used oil for
recycling - it renders the entire batch worthless!  I don't know the right
way to dispose of the stuff . . . may we have some suggestions?
TIA!
