Welcome back Tony. I hope the new venture is going well. I’m looking forward to many more of your build postings. Also, you make an excellent point about avoiding plastic master cylinders and going with all metal construction. I’m starting to feel better about this.
Roy, one of the features listed in the DOT 5 silicone specification from the link you gave indicates the fluid is non-flammable. It also has a few mil and SAE specs which is somewhat of a reassurance.
Tanks, Roy and Tony for the reply and help.
