Well, it isn't "designed" to -- it's designed to do the various things it's supposed to do and oh by the way it absorbs water. > Of course, no >one really ever does this except the anal retentive and racers. True, I'm afraid. >However, the cost of brake fluid changes every couple of years I'm sure >offsets the cost of having to replace even one seized brake caliper due >to internal rust. The other (and primary) issue is that brake fluid gets *hot* and its boiling point is drastically lowered by moisture. If it boils, i.e. some of it vaporizes in the system, strange things could happen such as the brakes having a mushy pedal and/or not releasing when you let off the pedal. > I changed the tranny fluid in my 86 last weekend (and put >Redline in).

Non-synthetic gear oil has a disgusting odor right out of the can...not to say that it's not a good idea to change the stuff. david David Beierl - Providence, RI http://pws.prserv.net/synergy/Vanagon/ '84 Westy "Dutiful Passage" '85 GL "Poor Relation"
