When I rebuilt my '40 Buick in winter of '00, I installed all new brakes front and rear, new lines, and new Master Power Brake booster, master clyinder, and prop. valve. It was my intentions to change over to Dot 5 fluid at this point since all was new, until I read the warranty on the MPB parts. It was VOID if I used silcone fluid. Naturally, I regressed to the old standby, Dot 4 and have lived happily ever after.I have never really had a problem with it,or Dot 3, except one time some 25 or so years ago on a brand new 1976 Harley Electroglide. The Dot 3 fluid would "boil away" from the rear calipers and you would have NO brake...fixed it by going to DOT 5 fluid, after a 2500 mi trip to Florida and back with no rear brake. I was younger and braver back then(read stupid).
