<<... I seem to recall it stating that, although
silicone fluid doesn't absorb moisture as readily as the glycol-based
fluids (DOT 3 & 4), it will permit moisture within the system (my memory
on this point is a bit foggy). Bottom line was, however, that whatever
brake fluid you end up using, it is a good idea to replace it every two
to three years (depending on atmospheric conditions where vehicle is
operated/stored), to reduce risk of moisture contamination.>>
Correct on both points!!
In the cas of 5, it has not been un-common to find water pooled in rear
cyls. on Caminos/Chevelles & Mid '65 thru Mid '75 Cads & also has been noted
in Professional Cars (Hearses & Ambulances).
