Water in brake system

I am now being told it is contaminated with something silicone based because it ate up the master cylinder diaphram I installed yesterday.
$100 to bled and flush. But Isuzu, nor just brakes will do that because they both say it is totally contaminated and needs everything replaced. Just my luck.

Power steering fluid would be my guess. This often happens by mistake.

Power steering fluid on the VX calls for Dexron III but I could see someone grabbing a silicone based fluid for the steering and then putting it in the brake reservoir - bummer.

I too recommend doing it yourself - and get this great product called SpeedBleeders that makes it MUCH easier - order four bleeders (sometimes sold in sets of 2 but did not see on their site although the p/n that follows is off a 2pc package) p/n SB7100 @

I flushed Lisa's brakes this Sunday in about 15 minutes and used a quart of Castrol SynPower Dot 3/4. Be surer to capture and properly dispose do the flushed fluid.

I am claiming this on Insurance and will let them fix it.
I'd try it myself, but am convinced it is shot.
The master Cylinder diaphram was so distorted within less than 24 hours after I replaced it, that this convinced me every other rubber part was probably affected. The 2 places I went would not even flush it because they said the contamination was so bad. I have concluded one of 2 things happened. the person I bought it from put the wrong fluid in it before I purchased it. But if that was the case I don't think it would run fine for 2 months and then just fail. My only other conclusion, and the one I am giving to insurance, is vandalism. I have no other explaination.
