I have been using Dot5 brake fluid since before 1992. When I replaced all my wheel cylinders and had PB unit rebuilt I flushed the system with alcohol and filled up with Dot5. I have had PB unit rebuilt since then (Ross Miller) because of one unusual occurrence - original rubber deteriorated and got down into vacuum chamber prohibiting vacuum piston from returning fully. Replaced with modern rubber.
