Re: [MV] Enlarged brake drum (potential) problem

I would not use DOT 5 (Silicone) brake fluid in a system that has some
new and some older rubber parts. In fact, when I had my master cylinder
re-sleeved and rebuilt by a nationally known antique restorer, the
lifetime warranty is void if DOT 5 fluid is used. Why? In the past,
they have completely replaced the entire brake system on an antique car,
filled it with silicone brake fluid, only to discover a gooey mess
later. Result? Completey replace the entire brake system AGAIN. After
this happened several times, they swore off of the silicone fluid even
though they had a case or two of the stuff around (and it ain't cheap!).

I decided to go with Valvoline's new SYNPOWER synthetic brake fluid
which is a glycol, non-silicone based fluid. So far so good. Anyone
else had any experience with this synthetic (non-silicone) fluid?

Just my two dollars worth (2 cents, adjusted for inflation).
