ABS system valves are VERY good, so unless you have initiated ABS, the brake fluid
in the ABS module is still isolated from the DOT5
Silicone brake fluid is NOT tolerant of moisture and will leave it to
pool at low spots. That then will have a high potential of corrosion 'there'
Silicone brake fluid will also aerate easily and will then be held
in suspension if jostled in any way. Why most DOT5 bottles will say to
leave the bottle to sit for an hour or so before pouring into your
vehicle brake system
It used to be a DOT4 vs DOT5 discussion, but now that DOT5 comes in
glycol, it now a glycol versus silicone discussion. There is also a
DOT5.1 (glycol and for ABS systems having mechanically cycling
proportion valves)
Glycol based brake fluids are some of the best paint removers known
and silicone is safe on 'most' painted surfaces
So Don, check the bottle and if no longer have them, the brand and
spec of the DOT5 you used. Am hoping it is glycol DOT5
