Voodoo brake fluid check

[Popcorn Man]

Got new calipers and was asked about having a fluid flush. I declined. Using a voltmeter I checked my fluid and it registered .17 with .30 being the the "Get a flush today" reading. After the new calipers were put in the reading was .00 This controversial measurement method indicates the moisture content of the brake fluid only. I put the negative probe on the negative chassie battery terminal and the positive probe into the master cylinder being careful not to touch any part of the cylinder (only the fluid). This method is still being tested by SAE but I think its a starting point. A little voodoo science keeps life interesting now that long awaited and talked tooo death caliper recall is underway.

Hey, I love that Voodoo that you do, unless it turns out to be doo doo.

Seriously, that actually makes sense. More water content = more conductivity. Hmmm - what scale on you VOM were you using?

I want to know too. This is the first I've heard of such a test.

Use search engine "Check brake fluild with DMM' It's from search-autoparts.com I use DCV on meter set at 20 This method checks moisture content only not contaminents.
