Silicone fluid voids warranty? No push to floor?

Got a master cylinder in for the TR and the sticker says, "Using silicone fluid voids warranty." :confuse:

??????????

Instructions say, " Don't push pedal to floor when bleeding or damage will occur to cylinder."


Huh?!?!?!?! On a new master cylinder ?!?!?!?!

I can see on an old one, but brand new ?!?!?!?

"Must hold mouth right, use of tongue may cause damage."

"Floss between bleedings."
 
Those warnings stickers are placed there by the distributor, not the manufacturer. No one has ever been able to figure out why, but I assume it's something to do with the fact that too many people don't know how to properly change from Glycol to Silicon fluid so they're covering their butts.

As far as not pushing down all the way, never heard of that one!
 
Safe to use silicone then? That stuff aint cheap and even though I'm going to sell this one eventually, I'd like to swap over to it.

Where's Tony when you need him. :frown:

But HEY! :angel:

The whole warning label thing has gone too far IMO. My favorite one was when I was getting some laser work done on my retinas. The label on the laser housing said "Do not shine in eyes."

I have heard from a couple sources that silicone will be phased out. Maybe switching now would be bad because you'll need to switch it back to a glycol based fluid. Check around before you take my word as gold though.

Interesting! Even more so to me as I've met Bob Adler, who is practically a neighbor. (Ok, he's about 8-10 miles away.) Quite the character...an extremely smart and well-educated man who suddenly decided he preferred playing with old Chevys to academia! He's got quite the (junk?)yard full of stuff as well as some very, very nice late 1940s and early 1950s Chevy cars and trucks that he drives regularly. ISTR he also has a Suburban from the mid- to late 1930s as well.
 
Yes, it's safe. Military vehicles use it, road vehicles use it, lots of things use it. DOT approved and it's been around for decades. I have it in three cars, no problems. I also still use Glycol in others, for different reasons.

For every guy who swears Silicon is the only good fluid to use, there's a guy saying exactly the opposite.
 
Wilwood saying not to makes me nervous. Might use dot3 simply cause it's cheaper, I have it here and this car isn't a keeper.
 
If it makes you feel better, an employee of Wilwood was in my garage last week working on an MG (not his) with silicon fluid in the system. Worked fine.
