Curious if anyone in here does this :
You can get a pretty good ballpark of the "moisture content" of the brake fluid in an automobile using a multimeter.
.
Open the hood, unscrew the brake fluid fill cap, set the multimeter to DC Volts (12 is fine).
Place the red probe in the fluid, and place the black probe to the master cylinder body - unpainted portion.
.
Let the multimeter settle down a few seconds .... if the readout is 0.3V or higher, it's time to flush-n-fill !!!
.
Anyone do this with a bike ?
