Re: Switching to DOT 5 (silicone) - order of events?

From what I understand, switching to DOT 5 is what requires all the flushing, etc. because of the incompatibility between glycol fluids (DOT 3, 4, and 5.1) and the silicone-based DOT 5.

In any case, the message as I understand it was the result of a study by Kanter itself

Kanter Study

The main reason to switch to DOT 5, from what I understand, is that the systems in these cars are vented to the atmosphere, not sealed with little bladders/diaphragms like in modern cars, so they absorb more water than present day vehicles, especially in areas with significant humidity, and DOT 5 does not absorb water, unlike the glycol-based DOT 3/4/5.1. I guess until/unless I do the change I'll just flush the brake system regularly.
