[W126 Coupe] Mineral Oil as a substitute for Brake Fluid

[stevetsg]

I bought special brake fluid years ago for my boat trailer because of the threat of water damage.  I'm not at home right now so I can't go to the garage to look at the label on the can but I'm sure that if you google it you will find what it is that I bought or you can call a boat shop.  What I really want to communicate though is that water in convential brake fluid is a serious matter and the damage that it can cause is costly.  The water proof brake fluid is a little more expensive but cheap in comparison to the risk that you take if your brake fluid is subject to water exposure.

I recommend all who are interested in the subject go to  http://en.wikipedia.org/wiki/Hydropneumatic_suspension  It talks about the care and use of the system and evolution of the fluids as time and problems affected the system.

The reason is that normal brake fluid is hygoscopic, i.e., attracts moisture, and must be changed every year to keep the brakes operating without incident.  This was the reason the manufacturer switched to a mineral based fluid for the hydropneumatic suspension, failure in the systems caused by moisture and dust.  Anyone made the switch or know who has?   Audi uses the Petosin mineral based fluids.  What about the modern MB or Audi cars?
