Thanks for the info on silicone fluid issues. I was unaware of this
swelling problem. I was speaking of the
problem. I deal with that by using Castrol LMA. I have never considered
using silicone fluid myself, so I withdraw any implied endorsement.

>3. It is well nigh impossible to completely clean out a used brake system.
>Any contaminants (such as water) in the system can congeal into gelatinous
>corrosive globs that can destroy a brake master cylinder.
>4. Silicone brake fluid seems to hold up really well to long term storage.
>Much better than regular brake fluid.
>5. Silicone brake fluid holds up so well to storage, that one can forget

>7. Following long term storage, silicone brake fluid makes an excellent
