Re: Mopar master cylinders - preference?

[Herb <zephyr9900@xxxxxxxxxxx>]

Several times!   We had about a 25% fail rate right away, on all the
vehicles we did.  Finally we just left well enough alone and stopped
converting to DOT 5 and the brake problems went away as they were purged
from the fleet

Years ago I used silicone brake fliud in my street rod ('23 t-bucket with
340, 727) drum rear and discs up front. I had a bad experience with it. I
started out with dot 3 fliud then I changed to silicone brake fliud because
it wouldn't eat paint. I drove it a short distance, less than 25 mi., and
the front calipers started dragging severely.  By the time I got it back
home I could roll up to a stop sign and stop without applying the brakes! It
seems that the silicone fliud expands as it gets warmer. The front pads
gently "float" on the rotors but it developed enough heat to expand the
fluid and the calipers and push the pads out against the rotors. I drained
the system and went back to dot 3 and never had anymore trouble. About a
month or two later an article came out in one of the street rod mags and it
warned of the same thing about silicone. A brake componet manufacturer
mentioned in the article said that silicone brake fluid did not belong in
automotive brake systems. (It is sometimes used in commerical applications
such as fork lifts.) Now having said that, that was several years ago so
maybe they have changed or improved the silicone fluid to avoid this problem
 Anyone else ever have that problem? Bill
