Brake Fluid Tester

["Steve D'Gerolamo" <steved3@xxxxxxx>]

I saw a brake fluid tester in the recent Griot's Garage parts catalog for 
$40. Apparantly this device uses a pair of electrodes to test your brake 
fluid for moisture content. I have always had my local mechanic change my 
brake fluid the month before every driving school, as required by BMWCCA. I 
have not bothered to change or check the brake fluid prior to autocrosses or 
after the last school of the season. My question is whether any or you have 
used this type of device and can vouch for its accuracy, or if I am better 
off just following the regimen I've already
established.
========================================================
I tried a Phoenix fluid tester a year ago with great expectations.  The
device was expensive (around $300) and the repeatability was very poor.  A
caveat when using any of these testers....make sure you sample the fluid in
the caliper and not that in the reservoir.  SD
