Very interesting piece of disinformation. Dot 5 is silicone in the United
States. The advantage of Dot 5 is it's permanence. To install into an
existing system you must strip and thoroughly remove any vestige of Dot3/4.
Once done it will not deteriorate under normal conditions. You can pour on
your hood and all it does is to shine the paint. It does not attack or swell
seals including the rubber ones in old English cars and bikes from the pre
sixties. I find Dot 5 performance quite acceptable but then I am not racing
down Pikes peak which is the example nay sayers like to use."Altitude
change" if there are air bubbles in system gives soft pedal. The fluid
knocks the hell out of master cylinder, wheel cylinder, brake hose and fluid
sales. Now you know why it's unpopular. Regards, Gary
