A final note:
The use of a product such as the Castrol LMA greatly reduces moisture.
The BIG point is that this extends the length of time between brake fluid
change. Any non-silicon must be periodically replaced, although many
folks never change theirs for the entire time they own the cars. As to
silicon, it does not absorb ANY moisture, so you do not have any in the
system, either in a puddle at the brakes or anywhere else. Moisture ONLY
gets into the system via absorption into the master cylinder reservoir.
This is of course, assuming you don't leave the hood open with the
reservoir lid off during a rain storm!!!!
This is NOT in any way intended to slam Castrol or any other brake fluid,
or anyone's choices in this arena! Just a central point of reference for
personal decisions.
Cheers!
