  I was going to make the change from DOT 3 to DOT 5 in my '53 but was advised against doing so. In changing over to DOT 5 fluid, it is important that the entire system is thoroughly cleaned and all remnants of the previous fluid is completely removed. It is also highly recommended that all the rubber components in the system are replaced concurrently with the fluid. If the components in the master and slave cylinders are sufficiently worn, they surely will leak unless they are replaced. However, many times people have gotten away with just purging the system thoroughly with mineral spirits and then pumping a couple of pints of DOT 5 fluid through the system to ensure the old stuff is completely removed. I didn't want to go through this hassle. I would make the change if I rebuilt the break system in it's entirety including the lines....

  I use Dot 5, but only when I have put in a complete new system( MC, wheel cylinders, lines, etc.).

  I put it in a a 1940 Ford Pickup in 1984. Still works fine, no brake problems yet. The whole system was new and still acts that way

1934 Ford's since 1972
