<VV> Re: DUAL MASTER CYL

Good point to remember for the future. I'm going to rebuild the wheel cylinders, use a new MC and replace the flex hoses anyway, so the rubber components were not of concern. 
Thanks for the input.

  Acetone not only has a similar moisture problem, it's deadly to the rubber parts. 
  Dry DOT 3/4/5.1 is supposed to be miscible with DOT 5. So, DOT 5 will chase the other stuff out of the system. Perhaps flush with fresh DOT 3 and then DOT 5...

    How about using acetone (a drying agent) instead of alcohol?  If that's not good, does flushing the DOT3 out with DOT5 result in some kind of residue problem? Does the DOT3 interact with the DOT5 and leave nasty stuff in the system?

    Thanks

      Given that denatured alcohol residue is a BYOTCH to remove without drying out the system with heat, a vacuum pump, etc. (do NOT blow air through it, as that will just add moisture!), I'd suggest NOT doing this. Flush with brake fluid.
